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.
