The 63828-0675 is a locator component designed for use with Molex hand crimp tools that incorporate the 63828-0670 Modular Crimp Head. Its primary function is to precisely position EconoLatch male and female terminals (series 150180 and 150181) within the tool's crimping nest, ensuring proper alignment before the crimp is made. The locator is pivoted to allow terminal insertion and then returned to its home position to secure the contact. This part is essential for achieving reliable, IPC/WHMA-A620 Class 2 compliant crimps on 16-18 AWG wires in low-volume or field repair applications.
