Frequently Asked Questions

What is the sensing range of the Leuze FT28.3/2N?

The FT28.3/2N offers a guaranteed operating range from 1 mm to 210 mm on a 90% white target, with an operating range limit of 250 mm. The integrated Teach function allows precise adjustment for different applications.

What is the advantage of background suppression?

Background suppression enables the sensor to ignore objects behind the taught sensing distance. This improves detection reliability on conveyors and in applications where machine parts or backgrounds are close to the target.

What is included with the sensor?

The package contains the FT28.3/2N sensor with an integrated 2 m PUR cable. No reflector is required because the sensor operates using the diffuse reflection principle with background suppression.
