MTA-156 Shrouded Header, 4 Circuits, 3.96mm Pitch
The 2-647123-4 is a TE Connectivity MTA-156 series single-row shrouded header with 4 positions on a 0.156" (3.96mm) pitch, designed for board-to-cable/wire applications. The shrouded 4-wall design and friction lock provide a secure, vibration-resistant mate with the corresponding MTA-156 receptacle housing. Through-hole solder termination with tin-plated posts (150.0µin thickness) suits wave-solder assembly, while the tin mating finish is rated for standard industrial environments at up to 600VAC.
At 4 circuits and 3.96mm pitch, this header is a compact power/signal interconnect for low-circuit-count harnesses — mates with TE MTA-156 receptacle housings (e.g., 640441-4) using standard 0.045" square pins. The 0.300" mating contact length and 0.125" post length provide a stable solder joint and reliable connection in through-hole layouts.
