Frequently Asked Questions - OW5010 IFM

How to install the OW5010 detector?

Point the detector at the object to be detected and mount it using the mounting base (ref. E20426). The object temperature must at least match the switching temperature.

What is the switching temperature of the OW5010?

The switching temperature is 350°C or 750°C depending on the device type. Check the nameplate for the exact value.

What is the maximum detection distance?

The detection distance can be up to 5 m. Beyond that, radiation losses in the air can affect detection, requiring a higher object temperature.

How to electrically connect the detector?

Disconnect power. Connect according to the diagram: for DC PNP, NPN or AC/DC. Use a miniature fuse if specified. Wire colors are BN (brown), BU (blue), BK (black), GN/YE (green/yellow).

Is the detector protected against short circuits?

The AC/DC output is not protected against short circuits. A short circuit can destroy the device immediately. For DC outputs, check the data sheet.

What accessories are available?

The mounting base (ref. E20426) is supplied. As an option, the protective sleeve (ref. E20427) protects against dust and steam and allows optical cleaning with compressed air.

How to clean the detector optics?

Use the protective sleeve (ref. E20427) to introduce compressed air and clean the optics without contact.

What to do in case of parasitic background radiation?

If the application produces parasitic thermal radiation (e.g. ovens), use a detector with a higher switching temperature to avoid false detections.

Can I use the detector in a dusty environment?

Yes, with the protective sleeve (ref. E20427) which protects the optics. In severe conditions, the sleeve is recommended.

How to calculate the detection diameter?

Use the formula: d = 2 × l × tan(α/2) + Ø, where l is the distance, α is the opening angle, and Ø is the object diameter. Diagrams are provided in the manual.

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

$$ \boxed {d = 2 \times I \times \tan \frac {\alpha}{2} + \varnothing} $$

$$ \boxed {I = 0. 5 \times \frac {d - \varnothing}{\tan \frac {\alpha}{2}}} $$

$$ \boxed {\alpha = 2 \times \tan^ {- 1} \left(\frac {d - \varnothing}{2 \times I}\right)} $$

$$ \alpha = \text {a n g l e o f a p e r t u r e} $$

$$ \mathsf {l} = \text {s e n s i n g d i s t a n c e} $$

$$ d = d i a m e t e r o f v i s i b l e a r e a $$

$$ \varnothing = \text {l e n s d i a m e t e r} $$

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.
