An external screw thread (M22 x 1.5) is provided to allow permanent installation using the PT2 or PT3 connector. Three standard types of connector are available for use with the SS1 standard sensor: Waterlogging sensor assembly is supplied complete with 1 m (3.28 ft) of high temperature three core cable for connection to an R1C automatic trap monitor. It can also be connected to an R16C automatic trap monitor using a special diode pack. A plug in connector for use with SS1 standard sensors. Supplied with Type 30 or Type 40 hand held indicators complete with 1 m (3.28 ft) of high temperature cable and male plug. A threaded in-line connector for use with SS1 standard sensors for permanent installations for use with the R1C or R16C automatic trap monitors (non waterlogging applications only). A right angled connector for use with SS1 standard sensors for permanent installations for use with R1C or R16C automatic trap monitors (non waterlogging applications only).
