Board-to-Wire Header for 3.96mm Pitch Harnesses
The 2-647123-3: This is a 3-position, single-row, shrouded header from the MTA-156 series, designed for board-to-wire applications. The 0.156" (3.96mm) pitch matches the MTA-156 receptacle housing and crimp terminal family, giving a direct solder-to-board interface for a 3-circuit harness.
Termination is through-hole solder, with a contact length of 0.125" (3.18mm) on the post side. The overall contact length is 0.550" (13.97mm), and the mating pin length is 0.300" (7.62mm) — enough to engage the receptacle contact fully. Both the mating and post contact finishes are tin, with a thickness of 150.0µin (3.81µm) on each side.
Temperature, Flammability, and Voltage Rating
The header is rated for 600VAC and operates from -55°C to 105°C, covering most indoor industrial and general-purpose applications.
