Aid to identifying proximity sensors
RHOMBERG Electronics has incorporated an ingenious feature into its range of proximity sensors - colour coding to identify type:
· Colour of stripe in sensor cable tells whether the sensor is PNP, NPN, AC or Namur;
· LED colour indicates normally open (N/O) or normally closed (N/C);
· Colour of cap denotes inductive or capacitive.
Furthermore, Rhomberg dc sensors are rated higher than most brands around, with a standard 10-60V dc power supply range as well as the capability of switching up to 400mA directly, without an external relay.
Rhomberg offers most sensors in 40mm diameter barrels maximum to provide for extra sensing distance. Convergent Water Controls 02 9667 1944.
