The unshrouded, push-pull fastening makes it a direct mate for standard IDC sockets or crimp receptacles with a 0.100" pitch. No keying or polarization — orientation is set by the pin layout alone.
The per-contact current is conservative for the 0.100" pitch; the real limit is the temperature rise across the full 20-position load, so derate if all pins carry current simultaneously in a warm enclosure.
Within the same BERGSTIK series, the 77313-124-64LF is a 64-position version with identical pitch, plating, and ratings.
