Different Types of Security Seals and Their Advantages
Cable seals. Cable seals are durable seals that are used to seal valves, locked doors, and other items that have a small opening through which a cable wire can be inserted. Some cable seals meet ISO 17712 ratings for high security, so can be used for high-security situations like international cargo shipping. Different size jobs require different cable lengths, although excess cable length can be easily trimmed. They also come in different cable diameters, typically ranging from 1.5mm to 5mm.
Bolt seals. Bolt seals are another high-security seal option that are designed with a complex locking mechanism yet are self-locking so do not require tools and are easy to put in place. They have a steel bolt and a tamper-evident body part that are manually attached to form a seal. They are customizable by color, print, and barcoding for additional security layers. These seals are ideal for containers, trailer door latches, and cross border shipments. These heavy duty seals require a bolt cutter to be removed.
Fixed-length plastic seals. Fixed-length plastic seals are among the strongest type of plastic seal, with breaking strengths ranging from 80-135lbs. These seals work exceptionally well for securing cargo for truck shipments. Fixed-length seals are inexpensive, so they are a good option when cost is a concern.
Plastic pull-tight seals. Pull-tight seals are similar to fixed-length plastic seals, except that they come in a wider variety of breaking strengths and are adjustable to match specific needs. For example, pull-tight seals can be used for sealing hazardous waste, fire extinguishers, cash bags, vehicle doors, and more. Adjustable plastic seals are a good option when you have various needs as they are versatile.
Wire seals. Wire seals also have multiple varieties similar to plastic pull-tight seals, but their metal wires make are less likely due to break. These are ideal for when the seals need to fit through small openings.
Metal strap seals. Metal strap seals are similar to fixed-length plastic seals, except for the material. Their material makes them more durable than plastic strap seals. You can increase the security level of metal strap seals with custom numbering, printing, and barcoding. Like the plastic option, metal strap seals are a good choice for trucking cargo.
Padlock seals. Padlock seals are relatively small seals and are extremely easy to use. They typically are used to prevent doors from being opened. Wire padlock seals are ideal for securing meters and drums, while plastic padlock seals are ideal for securing food and beverage carts, first aid kits, and zipper bags.
The crimp wire seal is one of the most commonly used seals for measuring and metering. These seals are composed of lead, aluminum, or aluminum alloys. A seal press or pliers can be used to squeeze the wire into the holes and seal it in place. When a seal press uses a hardened die, the seal may be matched to the press by the marks pressed into it. These might be simple patterns, or they could be numerals or characters.
Self-locking wire seals, such as barcoded seals, are preferably used nowadays. This is because when using self-locking wire seals, you don't need a crimping tool to secure the seals anymore, unlike crimp wire seals. which features a stainless steel locking plunger. This seal may be color coded and customized to suit the needs of the recipient.
Snap seals, on the other hand, are simple steel wire seals that let you bend and lock the seal shut with your hands, securing the wire in place as you do so. This necessitates cutting the wire or severely bending the seal to open. All Snap Seals are available in basic or branded versions. They may be ordered in either unfinished metal or colored metal.
Furthermore, wire-wrapped cup seals are the best way to detect tampering. The saw-toothed bronze cross locking ring is housed in this two-piece disc that is combined and linked with the wire within. This makes the seal so robust and compact that only razor-sharp cutting instruments can get through. Moreover, cutting the wire is the only way to remove it. Hence, no matter the case, proof of tampering will always be shown. Tamper evidence is critical in applications involving high value and potential danger, such as those for which these devices are being employed.
Uses:
There are many more applications for measuring and metering than can be covered in this brief overview. Utility metering is one of the most prevalent uses of security seals for measuring. Examples of well-known uses include taxi meters, laboratory test equipment, and fuel meters. Wires are commonly used to seal metering and measuring instruments in production facilities for filling, weighing, etc., such as on liquid delivery trucks and transfer points; truck scales; postal weigh scales; traffic count devices; remote weather stations; and water level sensors. There are a lot of options in these specifications.
How Wires, Fuses, and Connectors Work
Connectors are critical to today's cars. Without them, it would be nearly impossible to build or service a car. Whenever a bundle of wires passes through or attaches to a component of the car that might have to be removed, there must be a connector there to allow for that removal. A single connector can have more than 100 wires.
In the past, unreliable connectors have been the source of many electrical problems. Connectors have to be waterproof (modern connectors have several seals to keep out moisture), corrosion proof and provide good electrical contact for the life of the vehicle.
To make this connection, there are a total of 23 separate parts. The main parts are:
The shell
The pins and sockets
The pin retainer
The seals
The Shell
The shell is an intricate piece that has a complicated shape. There is a locking clip on the outside that holds the two halves of the connector together. There are holes for the pins, and there are special barbs that lock the pins in place once they are inserted. There are numerous grooves to hold seals and make sure things fit together tightly. All of these features are molded into the piece when it is made.
The Pins and Sockets
The pins and sockets are responsible for conducting electricity from one half of the connector to the other. These are made very precisely so that the pins and sockets fit together with just enough force to ensure a good connection, but not enough force to make connecting and disconnecting too difficult.
The pins are crimped to the wires using a special crimping tool. Part of the pin wraps around the bare wire, while another part clamps onto the insulation. This makes it harder to pull the wire away from the pin.
The Pin/Socket Retainer
The pin/socket retainer is a piece of plastic that slides into the connector from the front. It wedges against all of the plastic locking barbs so they can't release. This piece makes it nearly impossible for the pins and sockets to work their way loose.
The Seals
The seals prevent water from entering the connection once the connectors are locked together. Each connector has a rubber seal through which all of the wires are fed. This seal fits firmly into the back of the connector. One side of each connector has a round seal that keeps water from entering the space between the connectors once they are locked together.
We previously explored the benefits of pull-up cable seals, highlighting their superior strength compared to wire seals. But their utility extends far beyond just raw muscle. The right cable seal can significantly enhance security in a wide range of applications. Let's explore some common scenarios where cable seals provide an extra layer of protection:
Securing Shipping Containers: Cable seals are a cornerstone of global trade, safeguarding valuable cargo in shipping containers. Their tamper-evident design deters unauthorized access and provides clear evidence of tampering during transport. Choosing a high-security cable seal with a strong cable and unique locking mechanism discourages theft attempts and ensures the integrity of your shipment.
Trucking Industry: Cable seals play a vital role in securing truck trailers and cargo doors. They prevent unauthorized access to sensitive materials and deter pilfering during transport. The adjustable nature of pull-up cable seals allows for a secure fit on various trailer types, while the robust cable construction offers superior resistance to cutting tools compared to plastic security seals.
Protecting Utilities: Cable seals safeguard critical utility infrastructure, such as meter boxes and control panels. This deters tampering with meters, which can lead to revenue loss for utility companies. Choosing a weatherproof cable seal ensures it can withstand harsh elements and maintain its integrity over time.
Fire Safety: Cable seals can be used to secure fire extinguisher cabinets, ensuring extinguishers are readily available in case of emergencies. This prevents unauthorized removal or tampering with these lifesaving tools. Using a brightly colored cable seal also increases visibility, making it easier to locate extinguishers during critical moments.
Machinery and Equipment: Cable seals can be used to secure hatches and access points on valuable machinery and equipment. This discourages unauthorized access and protects sensitive internal components. Choosing a cable seal with a unique serial number allows for easy identification and tracking of equipment access.
Automotive plug wire seals, also known as automotive connector seals, are designed to protect electronic connectors in vehicles from moisture, dust, extreme temperatures, and harsh chemicals and fluids. These seals are often used in applications that require sealed power connectors, receptacles, and plugs.
Here are some things to consider when choosing automotive plug wire seals:
Material hardness: The material should be around 40-50 Shore A (ShA) durometer to provide the necessary tear resistance, compression, and durability.
Lubrication: Lubrication may be needed to help the wire pass through the seal during crimping and to reduce the risk of damage when the seal is inserted into the connector housing.
Environmental protection: Some connectors offer IP6k9k-rated environmental protection.
The durability and reliability of automotive components are becoming increasingly important. As a protective material, rubber parts are used in large numbers in automobiles. The importance of seals is self-evident. Especially for the protection of the wiring harnesses in the engine compartment and the lower chassis of the car. This is because these two areas usually have a high chance of being exposed to harsh environments.
There is a concept of a "wet zone" that needs to be known. Generally speaking, we call the engine compartment and the lower part of the car exposed to rain and water "wet zone".
Correspondingly, the cockpit and luggage compartment and other parts are basically not affected by rain, this part is called the "dry zone".
One of the biggest roles of the wire harness seal is to isolate the wet and dry areas, which is an application, common parts are assembled between the engine compartment and the cockpit to separate the dry and wet areas; there is also the left and right rear ABS harness where the need to assemble wire harness seals, specifically in the rear seat below (such as the Golf), where there is a wire harness seal to separate the internal and external parts, to ensure that the water at the bottom of the driving process will not leak into the cab.
Each qualified wiring harness will be tested for air wire harness sealing to ensure that the wire harness seal on the harness will work, generally, in the harness factory, we use vacuum test testing equipment to do the job. The equipment working principle is very simple, the wire harness seal is placed on the mold, the equipment provides a continuous increase in pressure value, the air inside out, within a certain time and pressure value, if the wire harness seal can withstand, is good, and vice versa, there are quality problems.
Connectors and other electronic components into the water in two main ways, the first is the external liquid penetration into its interior by the gravity of the earth's core, such as connectors without wire harness seals. The second way is water from the internal connection points of the harness (such as unprotected solder joints/crimp points/lap joints).
General electrical appliances in the work of a certain temperature, the internal air to form a certain pressure, when stopped working, the temperature drops, the internal pressure is also small, this will form a difference in air pressure, if the connector is poorly wire harness sealed, moisture will follow the gap between the multi-strand copper wire into the internal, resulting in functional failure. Therefore, the wet zone connectors are generally required to add wire harness seals.
