Laser fork sensor Sensor Instruments

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.
Measuring principle: Partial covering of the laser beam leads to a voltage at the analog output that is proportional to the degree of covering.
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.
The non-contacting measurement of fast-moving objects by means of analog laser light barriers of the A-LAS series now is further supported by the new A-LAS-CON1 control unit. Up to two A-LAS sensors can be connected to this control unit. The included A-LAS-CON1-Scope software allows a selection from several evaluation algorithms. Furthermore, an external signal for triggering also can be selected with the operating software, or one of the two analog light barriers functions as a trigger device, while the other laser sensor is used for measurement. This also makes it possible to measure larger objects while they are moving and, among others, allows the performing of measuring tasks such as the width of plug contacts, *gap-size* measurement of stamping parts, etc.
