Product details

The 1719740103: The UL94 V-0 liquid crystal polymer (LCP) housing ensures flame retardancy for equipment inside an enclosure. The brass contacts with tin plating on the post (78.7µin) and gold on the mating face provide reliable signal transfer and corrosion resistance in general-purpose environments.

This header mates with SL-series crimp receptacles that accept 0.100" (2.54mm) pitch housings. The polarizing key prevents mis-mating, and the latch holder secures the connection in high-vibration environments.
