The Alge PR1a Photocell is a battery powered device which is used to provide a start, split or finish pulse from a moving object as it passes through the infrared beam. The opposite reflector can be positioned up to 25m away from the photocell.
The PR1a can be used in a two different configurations depending on your requirements:
• Photocell with a Reflector (up to 25m between)
• Photocell with Photocell (up to 150m between)
All Alge PR1A Photocells can be universally with a reflector or as sender and receiver photocell. The photocell is also available with integrated WTN wireless radio module (2.4 GHz), which includes up to 15 different radio channels and 5 varying impulse channels. If the WTN module is selected it allows the photocell to wirelessly connect to other WTN devices within the vicinity, such as a TIMY 3 timer.
With its rugged, weatherproof casing and extendable cover the photocell is ideal for both indoor and outdoor use.
