Product details

Through-Hole Mount, Unshrouded, Push-Pull Retention

Unshrouded with push-pull fastening — no latch, so it relies on the mating housing's friction or a secondary locking feature for vibration resistance. The square pin (phosphor bronze contact material) mates with standard 0.025" square-post receptacles — common across the BERGSTIK® ecosystem and many IDC socket lines.

Sourced through independent distribution channels.
