Frequently Asked Questions

What is the pin count and body size of the SM04B-SRSS-TB connector?

The SM04B-SRSS-TB is a 4-pin, side-entry board connector measuring 0.236 inch long, 0.195 inch deep, and 0.114 inch wide, making it a compact option for board-to-wire interconnects in space-constrained layouts.

Contact plating on the SM04B-SRSS-TB uses which finish material?

This 4-pin connector features male contacts with a tin (Sn) finish on both mating and termination surfaces, and it is classified as non-Pb-free (Pbfree Code: No), using a leaded tin coating rather than a RoHS lead-free finish.

Design engineers selecting a compact wire-to-board interconnect often consider the SM04B-SRSS-TB for its side-entry mounting style.

The SM04B-SRSS-TB is a 4-pin, board-mount connector with a side-entry design and male contact gender, suited for wire-to-board connections in consumer electronics and industrial control wiring harnesses requiring compact 0.236 x 0.195 x 0.114 inch footprints.
