The latch lock snaps over the header shroud for positive retention. The Terminal Position Lock (TPA) Notched feature means the housing has a slot for a secondary lock that secures each terminal after insertion — a nice detail for production environments where a partially seated contact is a field failure waiting to happen.","metaTitle":"Molex Ultra-Fit 1722561104, 4-Position Receptacle, Obsolete","metaDescription":"Molex 1722561104 Ultra-Fit receptacle, 4 circuits, 3.50mm pitch, single row, crimp termination, latch lock.
