The 640713-2 is an enclosed strain relief designed for 2-circuit, in-line Universal MATE-N-LOK plug or cap housings. Made from UL94V-0 rated nylon, this component provides robust cable management and protection. It is designed for applications that do not require a wire-sealing insert and accommodates a wire bundle diameter range of .200 to .350 inches (5.08 to 8.89 mm). This strain relief helps prevent stress on wire terminations within the connector housing, ensuring a reliable connection as part of the 600V-rated Universal MATE-N-LOK system.
