Frequently Asked Questions - OW5007 IFM

What is the switching temperature of the OW5007 sensor?

The OW5007 sensor is available in two versions: 350°C or 750°C. Check the exact type on the device label.

How to mount the IFM OW5007 infrared sensor?

Orient the detector towards the object to be detected and fix it firmly. A mounting base (ref. E20426) is available as an accessory.

What output types are available on the OW5007?

The sensor offers three output types: DC PNP, DC NPN, and AC/DC. Follow the corresponding wiring diagram.

How to electrically connect the sensor?

De-energize the installation. Connect the wires: brown (BN) = power supply, blue (BU) = 0V, black (BK) = output, green/yellow (GN/YE) = ground if present. Insert a fuse if specified.

What to do if the sensor does not detect correctly?

Check that the object temperature is at least equal to the switching temperature. Ensure the object is within the detection cone (opening angle). Eliminate parasitic radiation (ovens, etc.) and use a protective sleeve (E20427) in case of dust or steam.

What is the maximum detection distance?

For ranges greater than 5 meters, radiation losses in the air appear. The object temperature must then be significantly higher than the switching temperature.

How to clean the sensor optics?

Use the protective sleeve (ref. E20427) and inject compressed air inside to clean the optics. Avoid any direct contact with the lens.

What accessories are available for the OW5007?

The main accessories are the mounting base (ref. E20426) and the protective sleeve (ref. E20427) for harsh environments.

How to calculate the detection diameter?

Use the formula: d = 2 × I × tan(α/2) + Ø, where d = detection diameter, I = detection distance, α = opening angle, Ø = optics diameter. The diagram in the manual gives typical values.

What to do in case of short-circuit?

The AC/DC output is not protected against short-circuits. A short-circuit can destroy the device immediately. After any short-circuit, check the proper functioning of the sensor and replace it if necessary.

USER MANUAL OW5007 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

$$ \begin{array}{l} d = 2 \times I \times \tan \frac {\alpha}{2} + \varnothing \ I = 0. 5 \times \frac {d - \varnothing}{\tan \frac {\alpha}{2}} \ \end{array} $$

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

$$ \begin{array}{l} \alpha = \text {a n g l e o f a p e r t u r e} \ \mathsf {l} = \text {s e n s i n g d i s t a n c e} \ d = d i a m e t e r o f v i s i b l e a r e a \ \varnothing = \text {l e n s d i a m e t e r} \ \end{array} $$

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.
