Frequently Asked Questions - OW5002 IFM

What is the difference between OWF models with 2°, 7° and 68°?

These aperture angles determine the field of view and detection distance. The smaller the angle, the more precise and long-distance the detection.

How to calculate the detection diameter?

Use the formula: d = 2 × l × tan(α/2) + ∅, where l is the distance, α the aperture angle and ∅ the lens diameter.

What is the maximum temperature for the amplifier?

The amplifier must be installed outside the hot zone, ambient temperature max. 60 °C.

Can I use a longer fiber optic?

Respect the bending radii of the fibers. Use fiber optics suitable for the hot zone (max. 250 °C).

How to electrically connect the detector?

Disconnect the installation from power. Connect according to PNP or NPN diagram: BN (brown) to L+, BU (blue) to L-, BK (black) to output, GN/YE (green/yellow) to ground if necessary.

What to do in case of a short circuit?

A short circuit can destroy the device immediately. Insert a miniature fuse according to the data sheet.

How to replace the fiber optic?

Remove the nut and washer, carefully remove the rubber gasket, remove the defective fiber, insert the new fiber, replace the gasket and secure with the nut.

What to do if the background causes spurious triggering?

Use a device with a higher switching temperature to ignore the background radiation.

What is the maximum recommended range?

Beyond 5 m, radiation losses in the air are significant. Increase the object's temperature relative to the switching temperature.

Where can I find the complete data sheet?

Consult the user manual freely downloadable from notice-facile.com or the manufacturer IFM's website.

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 temperature 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 accessory).

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.

α d l

Calculation of diameter of visible area/sensing distance/angle of aperture

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

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

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

α = angle of aperture

l = sensing distance

d = diameter of visible area

∅ = lens diameter

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.

Disconnect power, then connect the unit according to the wiring diagram

*Output not short-circuit protected.

Short circuit can lead to immediate destruction of the unit.

Replacement of fibre optics

Remove the nut 1 and washer 2.

Carefully remove the rubber packing 3 from the connection piece.

Remove the faulty fibre optics 4.

Slide the supplied new nut 1, washer 2, packing 3 onto the replacement fibre optics.

Insert the replacement fibre optics until the end into the hole of the switching amplifier provided for this.

Press the packing 3 into the connection piece.

Secure the replacement fibre optics by tightening the nut 1.

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.
