MTA-156 IDC Receptacle for 18 AWG Harness Wiring
The 0.156" (3.96mm) pitch matches the standard MTA-156 header footprint, and the orange housing signals the 18 AWG wire gauge — part of the series' color-coding scheme that prevents wire-size mix-ups on the line.
What the 80.0 µin Tin Finish Means for the Harness
Feed-Through and Daisy-Chain Wiring
The feed-through feature means the IDC contacts pass the signal through the housing, allowing multiple receptacles to be daisy-chained on the same cable without cutting or splicing. This is common in MTA-156 bus wiring for power distribution or signal routing inside an enclosure — you run one cable and tap off at each receptacle position.
