Board-to-wire header for 0.156" pitch harnesses
It mates with MTA-156 receptacle housings using the matching crimp terminals — the friction lock holds the pair engaged in moderate vibration environments, and the 0.156" (3.96 mm) pitch sets the PCB footprint and the wire-to-wire spacing in the harness.
Pitch, position count, and current ceiling
Current rating is not a fixed number; it varies by wire gauge per the MTA-156 application note. For 18 AWG wire, expect around 7 A per circuit; for 22 AWG, roughly 5 A. The tin-plated contact interface limits the continuous current below what the copper alloy pin can carry — derate for elevated ambient temperature above 85°C. Compared to the 10-position sibling 1-292164-1, this 12-position version adds two circuits in the same single-row footprint — the board space required is 1.56" (39.6 mm) vs 1.25" (31.8 mm) for the 10-position.
The header mates with MTA-156 receptacle housings (e.g., 3-640441-2 for 12 positions) using the appropriate crimp terminals. Through-hole solder termination with 0.125" (3.18 mm) post length suits standard 0.062" (1.6 mm) PCBs.
