Product details

3.50mm phone jack, through-hole right-angle

The STX-3150-3N-1 is a 3-conductor, 3-contact female phone jack from Kycon's STX-3150 series, accepting a standard 3.50mm (1/8") mini plug. It mounts through-hole right-angle, terminates by solder, and carries tin-plated brass and phosphor bronze contacts with a PBT housing rated -25°C to 85°C.

Same-series sibling: switch vs no-switch

The STX-3150-3N-1 and the STX-3150-3C-1 share the same 3-conductor, 3-contact layout, 3.50mm mating diameter, thread lock, and through-hole right-angle mounting — the difference is internal switching: the 3N-1 has no switch, while the 3C-1 carries two switches. The STX-3150-5C-1 adds two more contacts (5 total) and two switches, but keeps the same 3.50mm plug interface and thread lock.
