Under vibration, the ramp prevents the pair from backing out, which is critical in industrial and telecommunications equipment where the connector is inside a panel that sees fan or relay vibration. The square brass pins provide a reliable gas-tight interface with the receptacle terminal. The natural color aids visual inspection of pin alignment during assembly.","metaTitle":"Molex 0039299046 Mini-Fit Jr 5566 Header, 4 Pos, 4.2mm","metaDescription":"Active Molex 0039299046 — 4-position, 2-row, 4.20mm pitch vertical header with board lock.
