Photoelectric Sensor from Carlo Gavazzi meets all the latest standards for industrial doors

The compact size of the outdoor sensor allows easy on-wall-mounting, eliminating the need to build sensors into the wall. It is stylish as well as easy-to-use and no sensitivity adjustments are necessary. A new spherical lens is superior to previous designs based on internal parabolic reflectors, since it eradicates problems caused by dust and corrosion.

With a ±5 degree optical sensing angle, the PD98 uses modulated infrared light in the 880nm band to provide operating range up to 20m. Safety is enhanced by providing the emitter unit with a built-in test input, which mutes the emitter allowing sensor function to be evaluated. Testing is activated by the door controller.

Also built in is a synchronisation feature, which eliminates crosstalk and enables high neighbour immunity to be achieved.

The sensor works with a 12-24V AC/DC power-supply, requiring less than 20mA in operation. Output is via a 1A load SPDT relay, with LED indication. It is housed in polycarbonate for maximum lifetime and outstanding impact strength, and the housing provides IP54 protection against water splashes.
