According to EEC Directives, the output of NC plug exit models will be changing to pin 2 (NO will remain on pin 4). A plug cable to match these NC sensors MUST be a 4-wire type as 3-wire cables are connected to pins 1, 3 and 4 – contact IMO to check stock types. 4 3 1 2 (+) (Out) (OUT NC) See note below Please see – Full specification page 321 Mounting brackets page 330 Connector leads page 332 Dimensions (mm) SW36 SW36 4 12 12 LED ø13 M12x1 5 3 3 3 1 2 7 13 21 59 13 21 100 59 92 1 – in line cable exit with tang 2 – M12 plug-in exit 3 – Red, output state LED 4 – Unthreaded section on unshielded models 5 – Cable 3 x 0.34mm2 ø5mm x 2m long PVC 4
