Product information

The miniature optical sensors are the first

devices of their kind to offer an end-to- end

solution in a small single standard design —

from thru-beam sensor through to a distance

measurement device. As a result of this

design, the sensors are able to perform

practically all standard automation tasks.

The DuraBeam laser sensors are durable

and can be used in the same way as a

standard sensor.

The use of Multi Pixel Technology gives the

standard sensors a high level of flexibility and

enables them to adapt more effectively to

their operating environment.
