Reflex Sensors

Reflex Sensors

These sensors have the transmitter and receiver integrated into a single housing. The light beam emanated from the transmitter is reflected by the surface of the object to be recognized. A part of this light is detected by the receiver and it is transformed into a signal for switching by an evaluation unit integrated in the sensor.

Applications Checking

  • for the presence of objects
  • Object recognition
  • Object counting
  • Controlling of stacking heights
  • Controlling of passage ways
Reflex Sensors with Infrared light

Even though the light spot is invisible, the infrared light interfuses through dirt or objects in a better way.

HD03

Thanks to fine focusing optics, these sensors are especially well suited for the recognition of objects at short distances, and in front of backgrounds (e. g. in front of machine components, on conveyor belts etc.). They are preset at the factory to the specified detection range. The detection range can be adjusted with a potentiometer for the HD03PA.

Adjustment

Adjustments are performed with a potentiometer. With Teach-In versions, adjustments are made with the appropriate keys, externally or via the RS-232 interface respectively via the IO-Link interface.

Interface

Sensor functions can be activated and scanning results can be acquired via the RS-232 interface. A comfortable parametrization and a fast diagnosis is possible via the IO-Link interface and the original data is also available. Adjustment Adjustments are performed with a potentiometer. With Teach-In versions, adjustments are made with the appropriate keys, externally or via the RS-232 interface respectively via the IO-Link interface.
