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.
