Working Principle

The 4-103739-0 series connectors feature a two-piece design, with a male pin and a header. The male pin has knurled pins on the outside, which fit into the header, and a contact area on the inside. The header features holes, in an alternating pattern, to accept the knurled pins.

To install the connector, the male pin is inserted into the header. The knurled pins on the male pin fit into the holes in the header, forming a secure connection. When the male pin is fully inserted, the contact area on the inside of the male pin comes into contact with the contact area on the inside of the header. This forms an electrical connection that ensures the circuit is connected correctly.

For added security, the male pin can be locked in place by inserting a locking pin into the header. The locking pin fits into the holes to secure the connector in place, ensuring the connection is not accidentally disconnected.

Conclusion

The 4-103739-0 Rectangular Connector is a reliable, secure connector with low insertion force and simple installation. It is suitable for a wide range of applications, including industrial automation and industrial computing. The two-piece design of the 4-103739-0 series features a male pin with knurled pins, and a header with holes to accept the knurled pins. The male pin is inserted into the header to form a secure connection. The male pin can also be locked in place with a locking pin for added security.
