Phoenix Contact M8 & M12 Foil + Drain Cables are foil + drain cordsets that use aluminum shield to provide full coverage under the cable jacket. These cables come in two styles with either a drain connected to pin or with a drain not connected to the pin. The drain to pin connected style indicates drain wire loaded to a contact and are specified by FDP at the end of the product descriptions. These drain to pin cables allow noise to be carried through the connector via one of the contacts. The drain not connected style indicates drain wire does not connect to a contact or coupling nut and is exposed on open end of the cordset. These cables allow easy termination of drain at the open end of the cable and are specified by FDN at end of the product description. These foil + drain cables are ideally used in RFI protection.
