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
EN 61496-2:2013. 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 doors, escalator, travelators,
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 ISO 13849-1:2015.
