Product details

24-Way Single-Row Header for Wire-to-Board Power Distribution

The tin-plated male pin contacts (square shape) mate with standard MTA-156 crimp receptacles, making this a direct fit for existing harness tooling.

Pitch and Position Count — Footprint Fit Check

The 24-position single row is a specific fit — most competing single-row headers top out at 20 positions, so this part fills a niche for high-circuit-count wire-to-board in a single row. The 600VAC rating is substantially higher than the 125VAC on the 1-292164-1, making this header suitable for mains-voltage power distribution rather than just signal-level interconnects.

Mates with MTA-156 crimp receptacle housings (e.g., 640456 series) using standard 0.156" pitch contacts.
