New from Carlo Gavazzi is a diffuse photoelectric sensor that extends the company's background suppression technology to long-range operation.

The PD112 offers one-touch switching between door mode for entrance control applications and industrial mode for tasks such as packaging, wrapping and material handling and timber processing.

The sensor detects black objects at distances of up to 2m, and white or grey objects at up to 2.5m. Adjustment is fast and precise using the 28-turn potentiometer on the front panel.

In industrial mode, maximum operating frequency is 250Hz and detection is optimised for objects near to the background. A simple dip switch selection switches the PD112 to door mode, which automatically optimises performance of the sensor for detecting people and objects around automatic doors.
