Working Principle

The 89891-331H connector uses a latching mechanism to ensure a secure connection. It consists of a pair of mating halves, each with a corresponding plastic latch that engages when the two halves are connected. The latch ensures that the connection remains in place even when exposed to vibration and other external stresses. The two halves also feature anti-misalignment brackets, which keep the contact pins in place and eliminate possibility of misalignment.The 89891-331H connector also features corrosion-resistant contact pins which are designed to provide a more direct signal path. This improves the connector\'s electrical performance, and ensures a reliable connection even after many years of use. Additionally, the contact pins are gold plated to provide additional corrosion resistance.
