Principle
The ALGE photocell RLS1c is made with the most advanced electronics. You can use the reflective photocell RLS1c for a distance from 1 to 25 Metres. If you want a longer distance then 25 Metres you have to use the type RLS1cd,which works as a through beam consisting of seperate transmitter and reciever.
The photocell can either be powered from an ALGE timing device or internal C type batteries .
