Crimp the socket onto the stripped wire end with the appropriate Mini-Universal MATE-N-LOK hand or automatic tooling, then insert it into the matching receptacle housing until the locking lance seats. The tin finish on the contact mating surface mates with tin-plated header pins in the corresponding housing — no gold-to-tin galvanic concern in a dry, low-cycle application.","metaTitle":"TE Connectivity 770904-4 Mini-Universal MATE-N-LOK Socket","metaDescription":"TE Connectivity 770904-4 stamped socket for Mini-Universal MATE-N-LOK series.
