This wire harness integrates Molex’s Micro-Lock Plus 1.25mm pitch system, featuring a 4-circuit black receptacle housing (5055650401) and tin-plated female crimp terminals (5054311000). Factory-crimped and fully tested, it ensures consistent electrical and mechanical performance for mass production and prototyping. The 1.25mm pitch balances small size with robust connectivity, supporting both low-power signal and light current applications.
