Information

MTA-100 connectors accept discrete and ribbon cable wire sizes ranging from 22 – 28 AWG [0.4 – 0.08 mm2] with maximum insulation outside diameter of .060 [1.52] for terminating single wire and .050 [1.27] for mass termination of wires. Tin plated solid, fused stranded, or stranded (7 strands) wire with PVC insulation can be used on 22 – 28 AWG [0.4 – 0.9 mm2] MTA-100 connectors and 19 stranded wire on 22–24 AWG [0.4– 0.2 mm2] MTA-100 connectors. Only one wire to be terminated into an IDC contact slot.

The wire-to-post connector housing material is flame retardant thermoplastic, either UL94V-2 or UL94V-0 rated.

A full line of .100 [2.54] centerline headers completes the system. Headers are available with straight or right-angle posts, in flat, polarized or friction lock styles. Headers are available in 2 through 28 positions. Shrouded headers are available in 2 through 14 positions.
