(page 98) SERIES RN - Right-angle Hi-D Jax permits space-saving mounting on PC boards. Available in 2- and 3-conductor types with or without shunt circuits, which can mate with .25" diameter COMMERCIAL or TELEPHONE/MIL plug fingers. Right-angle jack permits tip of mating plug to be inserted parallel with PC board. Can be mounted on PC boards or combined PC board and panel/chassis. Mounted through .375" diameter holes (locknut and washer supplied) in panels and chassis up to .141" thick. Minimum mounting centers are .625". If insulated mount is desired, mounting with flat, non-conductive washer (not supplied) is recommended. PC terminals mount on boards up to .125" thick, and hand dip or wave soldering, is recommended. Three separate standoffs fit through board to provide stable mounting. Threaded bushing permits optional fastening to panel or chassis. SERIES RN110 - 2- and 3-conductor right-angle types mount in PC boards or panel/chassis. Bushing is .278" long.
