Background suppression photosensor

New from Carlo Gavazzi is a diffuse photoelectric sensor extending the company’s background suppression technology out to long-range operation. The new PD112 offers one-touch switching between door mode for entrance control applications and industrial mode for standard applications like packaging, wrapping and material handling and timber processing.

Best-of-breed sensing distances are achieved through Carlo-Gavazzi’s advanced triangulation technology: the sensor can detect black objects at distances up to 2m away, and white or grey objects at up to 2.5m. Adjustment is fast and precise using the 28-turn potentiometer on the device’s front panel and users can fine-tune the sensor to detect targets at the desired distance, distinguishing them from reflective objects just a few millimetres beyond.

A truly innovative feature of the PD112 is the mode operation selection. Set to traditional industrial mode, the maximum operating frequency is 250Hz and detection is optimised for objects near to the background. This ensures optimal performance in general industry automation applications such as pallet wrapping machines, airport baggage conveyors, or wood handling and plank stacking machinery.
