Product details

Board-to-Cable Header for 3.96mm Pitch Harnesses

Its 0.156" (3.96mm) pitch matches the MTA-156 receptacle family — a common choice for power and signal distribution in general-purpose and industrial equipment. The UL94 V-0 thermoplastic housing supports equipment inside enclosures requiring flame-rated materials.

Overall contact length is 0.700" (17.78mm), with a 0.450" (11.43mm) mating pin length that engages the receptacle contact fully.

ROHS3 compliant. The base product number is 644611; the full order code 3-644611-3 includes the natural insulation colour and tin plating.
