The 1.50 mm pitch keeps the connector narrow, suiting it for high-density harness assemblies where board space is at a premium. It terminates via crimp contacts (sold separately), meaning the wire is attached to a terminal first, then inserted into the housing — a standard process for automated or bench-top harness builds. The latch lock fastening type provides an audible and tactile click when mated, confirming full engagement without a secondary locking mechanism. ## Mating and Termination This plug mates with the corresponding CLIK-Mate 502578 receptacle housing (same series, same circuit count). The latch lock on the plug engages with a matching ramp on the receptacle — no tools needed for mating or unmating. Termination is crimp-style: the installer selects the correct Molex crimp terminal for the wire gauge, crimps it onto the stripped wire end, and inserts the terminated contact into the housing cavity until it locks. The housing does not include contacts; order the crimp terminals separately per the BOM.","metaTitle":"Molex CLIK-Mate 5025781401, 14-Position Plug, 1.50mm","metaDescription":"Molex 5025781401, 14-position plug from the CLIK-Mate 502578 series. 1.50mm pitch, crimp termination, latch lock.
