Product details

RCA jack, 2-conductor mono, right-angle PCB mount

The RCJ-042 is the 2-conductor mono member of CUI Devices' RCJ phono jack series, accepting the standard 3.20mm ID / 9.00mm OD RCA plug. It mounts through-hole right-angle with solder termination; the nickel-plated brass contacts and brass body are housed in a PA66 insulator rated -20°C to 85°C.

Board lock and unshielded construction

A board lock secures the jack during reflow and against cable strain; the unshielded body and absence of internal switches suit simple mono audio paths where shielding is not required.
