Product details

4-Position IDC Receptacle for 22 AWG Harness Assembly

Closed-End IDC for Assembly Reliability

The closed-end design blocks the last cavity, so an operator cannot push a wire past the final position — a common error on open-end IDC connectors that causes intermittent opens. The right-angle cable exit (free-hanging, in-line or right-angle mounting) lets the harness lie flat against the board, saving vertical space in shallow enclosures. The red housing colour is a visual aid for line-side sorting when multiple MTA-100 receptacles share a harness.
