The 0.138" (3.50mm) pitch and 0.130" (3.30mm) row spacing give it a compact but serviceable footprint — dense enough for multi-circuit power distribution, open enough for easy wire routing. The spring clamp termination on each female socket eliminates the need for a separate crimp tool: strip the wire, insert, and the clamp holds. This makes the 1-1871940-8 a natural fit for harness builds in industrial control panels, automation equipment, or test fixtures where wiring changes happen at the bench, not on a crimp press.
Spring Clamp Termination and Locking Ramp
The spring clamp termination accepts discrete wires — strip, insert, and the internal clamp engages the conductor. No crimp terminal to stock, no die set to change. In a free-hanging harness subject to vibration or cable pull, that ramp keeps the pair mated without relying on screw locks or secondary hardware. The gold-plated female sockets (11.8µin) handle moderate mating cycles — enough for periodic field service, but not a daily-connect duty cycle.
