PJ-320 TRRS Socket

3.5 mm / 1/8″ 4-pole AUX socket (TRRS)

As used on many split keyboards

Available in two main versions:

• PJ-320A – through-hole, as used on most split keyboard kits
• PJ-320D – SMD version – pins are bent to the sides at a 90° angle (to sit flat on the PCB). However, by simply bending the pins down 90°, these can be used as through-hole without problems. The pins will be flush with the PCB (they will not protrude through it), but they are very easy to solder.
