Laser analog light barriers
A-LAS Series
Laser analog light barriers and electronic control units
With the laser analog light barriers of A-LAS Series parallel laser light with homogeneous light distribution in round or rectangular cross-section is used for measuring, positioning, and detection of objects starting from a size of 0.01 mm.
With the laser analog light barriers of A-LAS Series parallel laser light with homogeneous light distribution in round or rectangular cross-section is used for measuring, positioning, and detection of objects starting from a size of 0.01 mm.
The A-LAS light barriers work according to the following measuring principle: The laser light beam that is emitted by a high-precision optical unit (aspherical surface made of glass) allows the detection of smallest objects (e.g. threads) even in case of a large transmitter/receiver distance (distances up to 100 m, depending on model and aperture).
The use of high-precision apertures in the transmitters ensures optimum adaptation to the respective application. The aperture guarantees a homogeneous light distribution on the beam and a sharp beam limitation.

Apart from a large variety of standard apertures special apertures can also be realised.
