Photoelectric (Opto) Sensors
Rhomberg photoelectric sensors must be interfaced with the Rhomberg SC410 monitoring relay to operate. This enables the unit to be powered from 240VAC but to switch a potential-free 10A C/O relay contact when the infra-red beam is broken. They are available in combined transmitter/receiver or separate transmitter & receiver formats.

RO2 Photoelectric (Opto-electronic) Sensors.
For use with Rhomberg SC410 relays

  • Separate transmitters and receivers, or transmitter & receiver in one unit
  • Interface directly to optional Rhomberg monitoring relay SC410.
  • Target or space sensing
