ESQ-122-34-S-T application field and working principle

Introduction

The ESQ-122-34-S-T is a rectangular connector header with a bidirectional right-angle contact. It has the capacity to accommodate additional mating parts and components allowing for a much easier connection than the traditional alternatives. It is most often found in applications such as industrial automation, automotive, medical, andmilitary electronics.

Specifications

The ESQ-122-34-S-T is constructed using a 2 piece design and is compliant with the industry standard D-Sub series. The male and female pins have a diameter of 0.012 inches and a centerline distance of 0.100 inches. Each connection has up to 80 contact points and a rated current of 0.5A. The insulation resistance of each female connector exceeds 1MΩ and the breakdown voltage exceeds 200V. It has contacts plated with a tin-lead alloy for improved protection against corrosion and electrical shocks.

Application fields

The ESQ-122-34-S-T is designed for use in various electronic applications. It is often used in industrial automation, automotive, medical and military applications due to its compact size, high contact current and insulation resistance. It can also be used in data acquisition and signal transmission systems, control systems, machine control, and instrumentation. In addition, it can be used in harsh environments due to its corrosion resistance and high temperature rating.

Working principle

The ESQ-122-34-S-T consists of two separate parts, the male and female connectors. The male connector features contact pins that are inserted into the female connector. When the connectors are mated, the contact pins make an electrical connection that allows signals to be transmitted. The contact pins are plated with a tin-lead alloy which helps protect against corrosion and electrical shocks. The contact pins have a high-temperature rating, allowing them to be used in high-temperature applications such as automotive electronics.

Conclusion

The ESQ-122-34-S-T rectangular connector header offers a durable and reliable connection solution for applications where traditional methods may not be suitable. It has the capacity to accommodate additional mating parts and components allowing for a much easier connection than the traditional alternatives. It is most commonly used in industrial automation, automotive, medical, and military applications due to its compact size, high contact current, high insulation resistance, and high-temperature rating.
