Introduction
The ELS 300, is a through-beam safety light barrier
and is certified as an active opto-electronic
protective device (AOPD) Type 2, according to
IEC 61496-2. It consists of an emitter (Tx) and a
receiver (Rx) which has a built-in controller with PNP
or NPN output, light or dark switching. A "Snap-In"
mechanism allows fast mounting in a mounting hole
with a diameter of just 12.5 mm. A green LED on the
rear side of the Tx indicates if the power is on. A
green LED on the Rx rear side indicates the output
status. The device is sealed and completely
protected against moisture and dust, according to
protection class IP65. Reliable operation is not
affected even by direct sunlight up to 100,000 Lux.

Applications
The ELS 300 through beam sensor family consists
of different types of sensors for automatic sliding
doors,
elevator
entrance gates and similar applications. Please refer
to the relevant national standards for the specific
application.
The ELS 300 can also be used as a safety light
barrier in the machine industry. In such applications,
the combination of the ELS 300 with a supervising
control unit (e.g. a programmable logic control,
PLC), can reach safety category 2 Performance
Level C, according to EN 13849-1.
