In these days, many equipments which employed IEC 20A (IEC60320C13) type inlets have come onto the global market of high-end audio. Weat Oyaide Electric who have aimed at responding the needs of users allthe time produced high capacitance IEC 20A connectors of P/C series.

Obviously, C-237/246/279 series inherited each soundcharacteristic of P/C series and are produced by applying high-qualitymaterials and plating techniques.
The contacts of C-237/246/279 are made from deoxidized phosphorbronze which had previously proved its superiority in the highperformance P/C series. It insures high conductivity, mechanicalcharacteristic and reduces vibration at the point of contact with noloss of signal transmission.
Inheriting P/C series, three kinds of plating variations expressthe difference of characteristics. The outer barrel is made frompolycarbonate which has superior mechanical strength compare to otherresinic materials.
