The closed end and polarizing key prevent reverse insertion and ensure correct orientation during assembly — a common source of rework in harness builds if omitted. ## Termination and Wiring — IDC for Speed, 22 AWG Only The IDC termination punches through the insulation in one stroke, eliminating individual crimp operations. This works with 22 AWG wire only — the slot geometry is sized for that gauge. The wire type can be discrete or ribbon cable, but the insulation diameter must be compatible with the IDC slot. ## Contact Finish and Duty Cycle","metaTitle":"TE MTA-156 4-643819-1 Receptacle, 11 Pos, IDC, 22 AWG","metaDescription":"TE MTA-156 4-643819-1 receptacle, 11 positions, 0.156\" pitch, IDC termination for 22 AWG discrete or ribbon cable.
