Proxima PFA Anti-collision photocell, yellow

PROXIMA PFA ANTI-COLLISION PHOTOCELL (YELLOW)

The modern PFA photocell is one of the elements of gate automation. Her an undoubted advantage is its rotatable transmitter and receiver head (190 °), whose assembly can be both inside and outside the door. The receiver's LED blinks help determine where the range limits are. IN when the photocell is set at the border, the LED of the receiver starts quickly flash.

Anti-collision PFA photocell allows you to build a security system gates where, due to their location, the photocell receivers receive infrared radiation not only from your transmitter. Thanks four working channels, the photocell receiver analyzes infrared radiation coming only from a transmitter working on the same channel as the receiver, though that even three additional interfering signals coming from other transmitters working on other channels.

The three TRANSMITTER POWER make the photocell a universal device. Thanks power setting options, we can use it for gates of various widths, thus avoiding reflection problems.
PFA has a system that sets the receiver's input to a violated state AFTER A FAILURE Receiver MICROPROCESSOR.
