Panel-mount phono-style jack uses through-hole PCB terminals and a three-hole mounting pattern. The mechanical drawing specifies a 12.5 mm body width, 12.0 mm body height, and 7.5 mm side depth. The front face includes an 8.3 mm diameter circular jack feature and a 10.7 mm reference outside dimension. The mounting pattern uses three 2.7 mm holes with 5.1 mm spacing shown in the drawing.
