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.","metaTitle":"TE 3-644038-4 MTA-100 Receptacle, 4 Pos, IDC, 22 AWG, Gold","metaDescription":"TE Connectivity MTA-100 4-position IDC receptacle, 0.100\" pitch, gold-plated contacts, 22 AWG, locking ramp.
