Product details

3.50 mm stereo jack, panel-mount right-angle

The SJ1-3543 is a 3-conductor, 3-contact female phone jack from CUI Devices' SJ1 series, accepting a standard 3.50 mm (1/8") mini plug for stereo audio signals. Rated 1 A at 12 VDC, it mounts through-hole right-angle to the panel with an M6 threaded bushing and includes mounting hardware and a nut. Contact plating is nickel and tin; the housing is brass with a PBT insulator, and the part is ROHS3 compliant.

Switch configuration across the SJ1 series

The SJ1-3543 carries no internal switch, unlike the SJ1-3544 (single switch, 4 contacts) and the SJ1-3545N (two switches, 5 contacts) — all three share the same 3.50 mm mating diameter, 1 A rating, and panel-mount right-angle footprint. For a no-switch requirement the SJ1-3543 and the solder-termination SJ1-3533 are functionally identical; the SJ1-3543 uses kinked pins while the SJ1-3533 uses solder terminals.

Frequently asked questions

What is the difference between the SJ1-3543 and the SJ1-3544?

The SJ1-3543 has no internal switch and 3 contacts; the SJ1-3544 has a single internal switch and 4 contacts. Both share the same 3.50 mm mating diameter, 1 A rating, and panel-mount right-angle configuration.
