Precise laser proximity with background suppression

The PS1 from ELTROTEC is a laser proximity that due to its adjustable optic allows for setting an either round or elliptical light spot in various sizes. Even in fast processes and short cycle times the sensor is not missing out on a single part: due to the switching frequency of 5 kHz the sensor can be used in assembly and supply systems running at high speed.

PS1 is mainly used for controlling assemblies and presence of small parts as well as electronic components on printed boards making high resolution an important feature and allowing detection of parts from 0.1 mm and up. Compact and easy to install these sensors are similarly suited for breakage control in machine tools and through the elliptical light spot adjustment reliably detect structured surfaces which otherwise might cause problems to small light spots. Easy adjustment and control as the red light shows a wave-length of 675 nm, meaning it is visible. The precise detection on point 0.1 mm will be done by mechanical potentiometer. Sensing range varies from 55 to 300 mm.

Because of its background suppression the PS1 will not be affected by either clear or changing surfaces. Detection of light or dark objects can be selected. Secure signal transmission to control is done via a switchable impulse extension reducing signal dropout by 40 ms.

Laser protection class of PS1 is DIN EN 60825-1 class 2, so no further protection activities will be required. Housing IP 65 can be used for all industrial purposes and reliably works even in vibrating equipment parts.
