Product details

2.5mm mono phone jack, panel-mount right-angle

The MJ-2508 is a 2.5mm mono phone jack from CUI Devices, a 2-conductor / 3-contact female connector with a single internal switch. Rated 1 A at 12 VDC, the unshielded jack uses tin-plated brass/copper alloy contacts and a PBT housing, terminating via solder eyelets for panel-mount through-hole right-angle installation.

Mating diameter and panel fit

The MJ-2508 accepts a 2.50mm (0.094", 3/32") plug — the sub-miniature headphone standard — and fits a 0.217" (5.51mm) panel hole, secured by an M4 thread lock and included nut. Within the CUI Devices phone jack family, the MJ-2508's 2.5mm mating diameter contrasts with the 3.5mm (1/8") mini-plug of the MJ-3536N and MJ-3502 — the MJ-2508 is the sub-miniature option for compact audio jacks.
