Rectangular Connectors - Headers, Male Pins

Rectangular connectors, which are also known as “headers” or “male pins”, are used in a variety of applications and have a range of different working principles. A 91687-404LF connector, for example, is a popular rectangular connector that is used in many industrial and telecommunications applications. This article will discuss the application fields and working principles for 91687-404LF connectors.

Application Fields of 91687-404LF Connectors

91687-404LF rectangular connectors are recommended for use in numerous industrial applications such as broadcast, audio, security, control, robotics, and measurement systems. Their design makes them well-suited for applications where space is limited and high contact density is essential.In the telecoms industry, 91687-404LF connectors are widely used in base stations, mobile phones, routers, switches, telecommunication boards, and wireless access points. They are designed to connect two or more electronic devices to one another in a miniaturized form factor.The compact size of 91687-404LF connectors makes them ideal for use in networking applications such as cable assemblies, Ethernet networks, optical communication networks, and patch panels. They are also used in automotive and aerospace industries, as well as in medical device manufacturing.

Working Principle of 91687-404LF Connectors

91687-404LF connectors are designed to provide secure connections between two or more electronic devices. They work on the principle of friction locking, which involves a column of rounded pins that are held in place by a press-fit interfacing material.The pins can range in size from 0.5mm to 2.0mm, and the total count can go up to 24 pins depending on the desired application. The pins have a low electrical resistance and are highly reliable, making them suitable for a wide variety of applications.The connector is equipped with a spring-loaded locking clip that latches the two devices together, making it easy to separate or reconnect as needed. The locking clip also protects the connection from extreme temperatures, vibrations, and other environmental influences that may affect the pins’ electrical resistance.The pins on 91687-404LF connectors also feature an extended service life, as they are able to withstand frequent insertion and removal without degrading. This is because the pins are made from gold-plated copper and have an oxide layer that resists corrosion and ensures durability.

Conclusion

91687-404LF rectangular connectors are a reliable and cost-effective way to securely connect electronic devices. Their small size and friction-locking pins make them suitable for a variety of industrial, telecommunications, networking, automotive, aerospace, and medical applications. They are also highly reliable due to their gold-plated copper pins and corrosion-resistant oxide layer, making them able to withstand repeated insertion and removal operations without degrading. All these features make 91687-404LF connectors an ideal choice for a wide range of applications.
