Function And Features - IFM Electronic efector 600 OWF Notice De Montage

Function and features

Infrared heat sensors absorb the heat radiation of objects and convert
it into a switching signal.
They are used for object detection or temperature monitoring.
Switching temperature 500°C/900°C (depending on the type of unit).
Installation
Mount the switching amplifier outside the hot area (ambient temper-
ature max. 60°C). A special mounting base is available as accessory
(order no. E20426) for simple mounting. Mount the fibre optics in the
hot area (max. 250°C) in the required sensing distance. Use a lens
attachment to extend the distance and to set the switch point more
accurately (available as accesssory).
The object must at least have the switching temperature of the sensor
and must cover the visible area which depends on the chosen angle of
aperture and sensing distance.
Notice! Do not bend the fibre optics sharply.
