USER MANUAL OW0003 IFM
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 350^ / 750^ (depending on the type of unit).
Installation
Align the sensor towards the object to be detected and mount it. A special mounting base is available as accessory (order no. E20426) for simple mounting.
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.
Calculation of diameter of visible area/sensing distance/angle of aperture
$$ \boxed {d = 2 \times I \times \tan \frac {\alpha}{2} + \varnothing} $$
$$ \boxed {I = 0. 5 \times \frac {d - \varnothing}{\tan \frac {\alpha}{2}}} $$
$$ \boxed {\alpha = 2 \times \tan^ {- 1} \left(\frac {d - \varnothing}{2 \times I}\right)} $$
$$ \alpha = \text {a n g l e o f a p e r t u r e} $$
$$ \mathsf {l} = \text {s e n s i n g d i s t a n c e} $$
$$ d = d i a m e t e r o f v i s i b l e a r e a $$
$$ \varnothing = \text {l e n s} $$
Sensing range diagram:
In the event of ranges of >5m radiation losses must be taken into account. The temperature of the object should therefore be much higher than the switching temperature of the sensor.
Electrical connection
Disconnect power, then connect the unit according to the wiring diagram.
DC PNP
DC NPN
AC/DC*
Note: insert a miniature fuse according to the technical data sheet, if specified.
Recommendation: check the unit for reliable function after a short cirucit.
Core colours of ifm sockets: BN = brown, BU = blue, BK = black,
GN/YE = green/yellow.
*Output not short-circuit protected.
Short circuit can lead to immediate destruction of the unit.
Operation
Check the safe functioning of the sensor.
If in the application wrong switching occurs due to background radiation (e.g. ovens), use units with higher switching temperatures.
For applications in difficult environments (e.g. dust, vapour) or in the event of heat reflections of the environment use infrared heat sensors with a protective tube (order no. E20427).
If necessary, keep the optics clean by means of passing compressed air into the connection piece of the protective tube.
