Rectangular Connectors are a type of electrical connectors consisting of plugs and receptacles which mate to establish an electrical connection. Among them, Headers, Receptacles, and Female Sockets are the most popular options. SFH31-NPPB-D11-SP-BK is one of the most frequently used rectangular connectors, and this article will focus on its application field and working principle.

Application Field

SFH31-NPPB-D11-SP-BK is a reliable solution for high current power applications. It offers a flexible solution that reaches up to 8.0A~20.8A. It is designed to meet the needs of many commercial and industrial applications such as automotive, computer, communications, medical, industrial controls, consumer electronics and more.

Its housing is designed with a ruggedness that has all the features of an industrial quality connector, including a tight positive locking for strain relief, reinforced terminals within the housing to improve resilience against potential pin breakage and large contact areas that reduce voltage drop. Its unique housing design also creates a quiet yet robust connection as it draws power from the connected device.

Working Principle

SFH31-NPPB-D11-SP-BK is designed to be used with or without a crimp die hole profiling tool, allowing it to be inserted into most common header housings. This reduces the cost of assembly and creates a quick connection. A sliding lock mechanism provides positive latching security and strain relief when used with zero profile latching headers. There is also a built-in keyway feature to ensure a secure connection.

The pins, which are screws with a head and a propellor-shaped head, are securely held in place by the pressure between a plastic insert and a rubber diaphragm. As a result, there is no need for soldering and provides an easy and fast connection. The contacts are permanently bonded so they won\'t loosen or short out during vibration or shock.

The contacts on the plug are also designed to minimize contact resistance and improve current flow, providing better power transfer. The contacts are enclosed in an epoxy housing, providing superior resistance to shock, dirt and moisture. The contacts are also non-reactive so they will not corrode with time.

Conclusion

SFH31-NPPB-D11-SP-BK is a valuable member of the rectangular connectors family, combining all the features mentioned above. It provides reliable and robust connections in a wide range of applications, offering high-end performance and low price. From automotive to consumer electronics, it delivers the performance needed for the most demanding applications.
