Self-contained Photoelectric SensorsPZ2 Series

Greatly improved serviceabilityMounting the sensor body and routing the cable can be performed independently, reducing time and labour.If replacing the sensor body with a new one because of damage, or if replacing the sensor body with a different model due to changes in specifi cations, you need only to replace the sensor body.

IP67 rated, waterproof constructionPZ2 sensors use a detachable cable and IP67 rated construction for peace-of-mind in sites where equipment may get wet.

P.R.O.* function provides stable detection of mirrored surfaces (PZ2-61)

* Polarised Refl ection Optics

In the case of mirrored surfaces, the horizontal light is not received because it is refl ected in the same state when it hits the detected object.

The polarisation of the horizontal light emitted by the transmitter is interrupted by the refl ector, and it returns to the receiver as scattered light.

Refl ectorTransmitted light waves are horizontal.

When light hits the refl ector, its polarisation is interrupted and it is refl ected in all directions.

Refl ectorTransmitted light waves are horizontal.

Polarisation remains unchanged for mirrored surfaces.
