Board-to-wire header with a locking ramp
The 1-770968-1: This is a 4-position, 2-row header from the Mini-Universal MATE-N-LOK series, designed for board-to-cable/wire applications. The 4.14 mm pitch and matching row spacing define the PCB footprint that mates with the standard Mini-Universal receptacle. A locking ramp on the header engages the receptacle latch for vibration-resistant retention — no secondary locking hardware required.
Gold mating interface and board lock anchor
The male pins carry a gold mating finish at 30.0 µin thickness, which supports repeated mating cycles without oxidation — a practical choice for field-serviceable connections where the harness is disconnected more than a few times. A board lock feature holds the header in place during soldering and provides additional shear resistance against cable strain after assembly. The 4-wall shrouding protects the pins from accidental shorting and guides the receptacle into alignment during mating.
