NOTE: (pin connections): At present, all plug exit sensors
have the output on pin 4. 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.
