Roger Technology R90/F4ES Photocells
R90/F4ES
Pair of external photocells synchronized 24V AC/DC (max. 4 pairs).
The external photocells R90/F4ES are presence detectors synchronized, with infra-red technology powered by 24V AC/DC, which allow obstacles to be detected which are present on the optical axis between the transmitter (TX) and receiver (RX), can be used for automatic inputs.
These sensors are intended for installations with mounting surfaces which are flat and parallel to each other, which permit a proper centring between the TX photocell and the RX photocell.
Moreover, they allow the synchronisation of a maximum number of 4 pairs of photocells.
