Product details

Board Layout Fit for the 9-Position Header

The 0.400-inch (10.16mm) mating pin length engages the receptacle contact fully, and the 0.175-inch (4.45mm) solder tail gives enough through-hole length for a solid fillet on a standard 1.6mm PCB.

This header mates with MTA-156 receptacle housings that accept the corresponding crimp socket terminals. The 1-wall shroud guides the receptacle into alignment, and the friction lock engages the ramp on the receptacle housing. The 600VAC voltage rating covers most panel and industrial control circuits.
