3-Position Right-Angle Header with Friction Lock
The 3-641210-3 is a single-row, 3-position header from the TE MTA-156 series, designed for board-to-cable/wire applications. It uses a 0.156" (3.96mm) pitch and mounts through-hole with a right-angle orientation, keeping the wire exit parallel to the PCB. The friction lock provides positive retention against the mating housing, a practical feature for assemblies that see moderate vibration or cable strain. Mating contacts are gold-plated to 30.0µin (0.76µm), a thickness suited for repeated mating cycles and corrosive environments; the solder tails are tin-plated for reliable wave-solder wetting.
