Amphenol’s plugs and sockets range continually expand to meet the needs of our customers. The success of the M-Series phone plugs led to the RCA series being developed. The Miniature XLR range was a natural progression from our standard XLR series as the demand for smaller interconnects increased.

The latest addition to the range is a professional grade 3.5mm phone plug designed for applications that require a robust interconnect.
