Wire-to-Board Plug Housing for 1.50mm Pitch Harnesses
The Molex 5025781100 is an 11-circuit plug housing from the CLIK-Mate 502578 series, designed for wire-to-board interconnects at a 1.50 mm pitch. This single-row, free-hanging (in-line) housing accepts crimp terminals — the contacts are ordered separately, so the BOM needs the matching terminal part number alongside this housing. The latch lock fastening gives an audible click when fully mated, holding the pair together in applications where vibration could work a friction-fit connector loose. The 1.50 mm pitch keeps the board footprint compact — useful when routing multiple signal lines through a dense PCB layout.
Position Count and Pitch — What Drives the Fit
The 11 positions at 1.50 mm pitch define the board footprint and the mating receptacle it pairs with.
Termination and Mating
Crimp termination — the housing accepts non-gendered contacts that are crimped onto the wire before insertion. The latch lock engages with the matching CLIK-Mate receptacle housing.
