Model PSAFP1/PSAFP2 Proximity Sensor

Brand: Red Lion Controls

Inductive Proximity Sensors detect the presence of metal objects that come within range of their oscillating field and provide target detection to “zero speed”. 

Internally, an oscillator creates a high frequency electromagnetic field (RF) that is radiated from the coil and out from the sensor face. 

When a metal object enters this field, eddy currents are induced into the object. 

As the metal moves closer to the sensor, these eddy currents increase and result in an absorption of energy from the coil that dampens the oscillator amplitude until it finally stops.
