Photocell RLS1n

The ALGE photocell RLS1n is made with most advanced electronic. You can use the reflection photocell RLS1n for a distance from 1 to 25 Meter. If you need a longer distance than 25 Meters you have to use the type RLS1nd, which consist of a separate transmitter and receiver photocell.

Principal:

The transmitter of the photocell sends a modulated infrared beam. The receiver controls the infrared beam and makes an impulse for each interruption

If transmitter and receiver is built into one case we call it reflection photocell. The infrared beam is sent to a reflector. The function of the reflector is like a mirror, which reflexes the beam to the receiver.

The other type of photocell (RLS1nd) has on one side a transmitter and on the other the receiver. The infrared beam goes direct form the transmitter to the receiver.
 

Types of Photocells:

 

RLS1n	Infrared reflection photocell
RLS1nd	Infrared photocell with separate transmitter and receiver
RLS3c	Three-fold-photocell for athletic

Power Supply for the Photocell RLS1n:

The photocell is supplied by a 3-core cable from the timing device, or by the internal battery. As internal battery you can use a Alkaline Baby Battery or a NiCd Baby Rechargeable Battery. If you work with the internal battery you can use a 2-core cable between the timing device and the photocell (e.g. ALGE cable reel KT300 with 300 m fieldtelephoneline)
 

The internal battery supplies the RLS1n for:

• Alkaline Baby Battery: about 40 hours
• NiCd Baby Rechargeable Battery: about 18 hours
