Right-angle 5-position header for MTA-156 wire-to-board
The 3-644613-5 is a 5-position, single-row header from the MTA-156 series, designed for board-to-cable/wire applications. It mates with standard MTA-156 crimp-socket receptacles, completing a wire-to-board interconnect at a 0.156" (3.96 mm) pitch. The right-angle through-hole orientation routes the cable exit parallel to the PCB, saving vertical clearance in enclosures where a straight header would interfere with a cover or adjacent board.
Friction lock and shrouded wall for secure mating
A friction lock on the shroud engages the mating receptacle's latch ramp, providing positive retention against vibration and cable pull. The single-wall shrouding protects the male pins from accidental stubbing during handling. Contact finish is 150.0 µin tin on both the mating surface and the solder post — adequate for moderate mating cycles in a controlled environment, though not rated for repeated high-cycle field service.
Active production and sourcing posture
RoHS3 compliant and rated UL94 V-0 for the glass-filled thermoplastic housing, meeting standard flammability requirements for equipment inside an enclosure.
Mating half and harness assembly
The mating connector is a standard MTA-156 receptacle housing loaded with the appropriate crimp terminals. The friction lock on the header engages the receptacle's latch for a secure mated pair. Operating temperature range is -55°C to 105°C, covering most industrial and general-purpose environments without derating concerns at the low end.
