RJ11F/RJ11FTVX Harsh Environment Connectors

Amphenol Socapex RJ11F and RJ11FTVX Rugged Connection System allows the use of a standard phone RJ11 connection in harsh environments. With the patented RJStop® system a designer can use a standard RJ11 cordset with a metallic plug that will protect the cordset from shocks, dust, and fluids. No hazardous in-field cabling is required. Use the hand tool (RJ11FODE) for the insertion and removal of the receptacles and plugs.
