Product details

3.5 mm sealed jack for panel-mount audio

The SJ-3551B-MSMT-TR-67 is a female phone jack from CUI Devices' SJ series, accepting a standard 3.50 mm (1/8") mini plug for stereo (TRRS) audio signals. Rated 1 A at 12 VDC with gold-plated copper alloy and titanium contacts, it mounts board cutout, surface-mount right-angle with solder termination.

IP67 seal with included O-ring

IP67 rated — the connector ships with an O-ring that seals the panel cutout when mated, keeping washdown and outdoor moisture out of the enclosure. Operating temperature range is -30°C to 85°C, covering industrial and outdoor audio equipment.

Positioning within the SJ series

Within the SJ series, the SJ-3551B-MSMT-TR-67 carries a single internal switch and 6 contacts, while the SJ-3553A-SMT-TR-67 has no internal switch and 5 contacts — both share the same 3.50 mm mating diameter, 1 A rating, and IP67 seal. The SJ-3542AS-SMT-TR-67 adds a shielded shell for EMI-sensitive applications, also with 5 contacts and no switch.

Frequently asked questions

Will the SJ-3551B-MSMT-TR-67 drop into a panel specified for the SJ-3552B-MSMT-TR-67?

The SJ-3551B-MSMT-TR-67 and SJ-3552B-MSMT-TR-67 share the same 3.50 mm mating diameter, 0.551" (14.00 mm) mating depth, IP67 rating, and board cutout SMT right-angle mounting — the difference is signal lines: the SJ-3551B-MSMT-TR-67 is a 4-conductor (TRRS) jack, while the SJ-3552B-MSMT-TR-67 is a 5-conductor (TRRRS) jack.
