3.5mm TRRS jack, through-hole right-angle
The STX-35061-4T is a 4-conductor (TRRS) female phone jack from Kycon's STX-35061 series, accepting a standard 3.50mm mini plug with a mating depth of 0.551" (14.00mm).
Position count across the STX series
The STX-35061-4T's 4-conductor TRRS layout sits between the 3-conductor TRS of the STX-3501-3N and the 5-conductor TRRRS of the STX-353K7A-6N-KTTR — all share the 3.50mm industry mating diameter and through-hole right-angle orientation, so match the conductor count to the audio channel requirement.
