This single-row, free-hanging (in-line) housing accepts female socket contacts via crimp termination — the latch holder locks the pair together against vibration, making it a fit for automotive interior, industrial sensor, and consumer electronics harnesses where the connector sees field movement or thermal cycling. The nylon insulation handles -40°C to 105°C, so it lives comfortably in an engine bay or an outdoor cabinet. ## Contacts Not Included — Plan Your Terminal Order This housing ships as a bare shell — the note reads Contacts Not Included. You order the matching crimp terminals separately, which means the BOM line for this connector is two line items: the housing and the socket contacts. The 1.00 mm pitch and single-row layout keep the footprint small, but the real space savings come from the latch holder, which eliminates the need for a secondary lock on the harness side.","metaTitle":"Molex Pico-Clasp 5019390400, 4-Position Receptacle Housing","metaDescription":"Molex 5019390400 Pico-Clasp receptacle housing, 4 circuits, 1.00 mm pitch, crimp termination, latch holder, -40°C to 105°C, ROHS3.
