XC Series Electrical Connectors

This connectors is widely used in aviation, aerospace, marine, railway, field communication and various instruments

Brief Introduction

    This series is a low frequency electrical connector. It has 9 shell sizes, 4 contact sizes, 32 insert arrangements from 1 to 62 poles.  Bayonet coupling provides quick and easy operation, reliable connection, vibration and shock resistance. Hyperboloid socket contact leads to low insertion force, low contact resistance and high reliability. There are in total 5 receptacle models It is in compliance with Chinese military standard GJB2889.
