Product details

Wire-to-board header for basic power and signal routing

Rated 7.5A per contact at 250VAC, it suits general-purpose, industrial, and lighting applications where a simple, reliable power or signal interconnect is needed. The friction lock provides retention against moderate vibration without requiring a secondary locking mechanism.

Mates with a 3.96mm-pitch Economy Power receptacle housing (crimp terminals required, not included). Terminates via through-hole solder to the PCB; the 0.145" (3.68mm) post length fits standard board thicknesses. The 1-wall shrouding protects the mating interface and guides the receptacle during assembly.
