Sensor Target greater BEST... - Page 15 To minimise electromagnetic interference or ‘noise’, the sensor should be mounted away from motors, generators and such like. pOWer supply be sure to use a 24 V DC (100 mA) power supply. Mechanical insTallaTiOn All sensors come with a 1 m cable and a mounting nut as standard. Longer cables are available to order.
- Page 16 eLectRicaL inStaLLation WiRing (aLL MoDeLS) Check the distance between the sensing head and the electronics module, and between the electronics module and the instrumentation. If necessary, the sensor can be ordered with a longer cable between the sensing head and the electronics module. The output cable from the electronics module should have an outer diameter between 3.0 and 6.5 mm, with conductors of size 28 to 18 AWG.
