JST SM 2.5mm 4-Pin Wire-to-Wire Connector — 22AWG Pre-Crimped Terminal Wire

JST SM 2.5mm 4-Pin Wire-to-Wire Connector — 22AWG Pre-Crimped Terminal Wire

The JST SM 2.5mm series is the go-to wire-to-wire connector for LED strip connections, consumer electronics internal harnesses, and industrial enclosure wiring. Unlike wire-to-board connectors, the SM arm-lock mechanism provides positive retention between two cable assemblies — no PCB header required. This 4-pin configuration uses SSM-02T-P0.5 contacts pre-crimped onto 22AWG tinned copper wire, rated 3A / 250V AC/DC.

Why Choose This Connector?

• ✅ JST SM arm-lock mechanism — positive wire-to-wire retention, no PCB header required
• ✅ 4-pin configuration — ideal for LED strip, RGBW, and 4-wire sensor harnesses
• ✅ 22AWG pre-crimped terminal wire — ready to mate, no crimping tool required
• ✅ 3A / 250V AC/DC rated — suitable for LED power and signal wiring
• ✅ UL E60389 listed, RoHS compliant — suitable for commercial and industrial applications
• ✅ 2.5mm pitch — compact, space-efficient wire-to-wire connection
