The housing is black with a closed end, and the locking ramp holds the mated pair in place without a secondary latch. Tin contacts with 80.0µin (2.03µm) thickness handle low-cycle, cost-sensitive harness work — think appliance wiring, control panels, or internal power jumpers where the connector mates once and stays. ## Termination and Wire Prep IDC termination means no stripping, no crimping — the connector presses onto the cable in one stroke. The 24 AWG wire gauge is the target; the forks pierce the insulation and grip the conductor. For ribbon cable, watch pin-one every press — the closed end and keying ramp orient the connector so the first position aligns with the ribbon's edge. ## Mating and Compatibility This receptacle mates with the standard MTA-100 header family — unshrouded or shrouded, straight or right-angle, through-hole or surface-mount. The locking ramp clicks into the header's matching detent. No special tooling beyond the IDC press fixture; the connector is keyed to prevent reverse insertion.","metaTitle":"TE MTA-100 3-644312-3 Receptacle, 3 Pos, 0.100\" Pitch, IDC","metaDescription":"TE MTA-100 3-644312-3 receptacle, 3 positions, 0.100\" (2.54mm) pitch, IDC termination for 24 AWG discrete or ribbon cable.
