VAL-U-LOK Connectors with Terminal Position Assurance (TPA)

TE Connectivity AMP's VAL-U-LOK product line has been expanded with models accommodating TPA devices to help prevent contact back-out. These additions to the 4.2 mm (0.165 in) centerline product family are double row devices. Rated up to 600 V_AC and up to 9 A per line, they offer up to 24 positions as panel- mount plugs, free-hanging plugs, and receptacles. The connectors with TPA are intermatable with existing VAL-U-LOK connectors and headers, supporting wire-to-panel, wire-to-wire, and wire-to-board applications. The crimp, pin-and-socket contacts for discrete 26-18 AWG wires are designed for the new housings and work with the TPA devices. Snapping the TPA devices into place helps to assure contacts are fully seated in the housing and provide secondary protection against a contact backing out of its cavity when subjected to vibration, shock, or pulling force.
