Terminal blocks, headers, plugs, and sockets are essential components for electrical wiring. They enable cables and wires to be connected to an electrical device securely and easily. The VM0455020000G terminal block is a product which can facilitate reliable electrical connections. This article describes the application field and working principle of the VM0455020000G terminal block.

Applications

The VM0455020000G terminal blocks are specially designed for use with all types of switches, relays, temperature sensors, solenoids and radios. They are suitable for environments that need EMC (electromagnetic compatibility) compliance, including medical and automotive, especially in cases where long-term reliability is a primary concern.

The VM0455020000G terminal blocks are suitable for applications where space is an issue, as they can be mounted onto a printed circuit board (PCB) and connected using more traditional methods such as ‘wire-wrap’. This feature minimises the physical size of the module as it requires fewer components for installation. Additionally, their low profile nature enables them to be used in applications requiring efficient thermal management.

The VM0455020000G terminal blocks are also suitable for areas, where shock and vibration is expected as part of its environment, such as in the process industries and off-road vehicles. They are tested according to specified vibration and shock levels, and offer superior performance in harsh environmental conditions.

Working Principle

The VM0455020000G terminal block transmits electrical signals between the contact points. Its electrical connection is made by a device such as a screw, spring, or hinge contact which presses against the contact points of the wire or cable. The device is typically made of metal and is designed to withstand both high voltage and current.

To ensure a high quality connection, the contact surfaces of the VM0455020000G terminal block must be clean, free from burrs and damaged insulation. To facilitate this, the contact surface is subjected to a dielectric ‘wipe-test’, where each pair of contact points is subjected to 100% coverage with a passed voltmeter test. The contact surface is also conductively coated to ensure low contact resistance, which helps protect the connections against arc faults and optimises operation.

The VM0455020000G terminal blocks are also designed to provide high performance when it comes to surge protection. The contact points are made from high-grade material, which provides superior protection against voltage spikes and is also self-cleaning. To further enhance the protection, it is also designed to provide thermal protection; to ensure it does not become damaged due to overheating.

Conclusion

The VM0455020000G terminal block is a reliable and robust solution for electrical wiring, especially in environments which require EMC compliance. It is suitable for use in industrial, automotive, and medical applications, such as switches, relays, temperature sensors, radios, and solenoids. It provides high performance in harsh environments, with its dielectric and conductive coating making it suitable for use in areas where shock and vibration is expected. Furthermore, its surge protection adds an extra layer of security to all electrical connections.
