 Carlo Gavazzi has introduced a long range diffuse photoelectric sensor with background suppression technology. The model PD112 will detect black objects at distances up to 2 m, and white and grey objects at up to 2.5 m. Using triangulation technology, the unit is said to be easily and precisely adjusted, with a 28 turn potentiometer.
The user can fine tune the sensor to detect the target at the desired distance, while ignoring reflective objects millimetres beyond.
Each model has both NPN and PNP output, which is automatically detected by the sensor when wired. Normally open or normally closed output can be selected via a DIP switch. Two adjustable timers (1 to 16 s) for ON and OFF delay are provided.
The sensor can be operated in a traditional industrial mode, which is suitable for applications such as material handling, packaging and wrapping, and wood processing. By making a DIP switch selection, the unit can also be operated in a door mode, which automatically optimizes the performance of the sensor for detecting people and objects around automatic doors. This mode allows the sensor to be remotely tested by a door controller, making the sensor compliant with door industry safety standards.
The PD112 is available with a cable or M12 plug.
