The LHT 81 M 400 laser sensor has a captivating robust metal design. Clearly visible LEDs ensure that the switching and operating statuses are displayed clearly, even from a distance. No tools are required to set the switching point, and users have no need to worry about damagingor overwinding a sensitive setting screw. The limit areas are protected by overwinding protection and are indicated by a noticeable click.The process for setting the sensing range is also different. The range in most sensors is limited to one single turn but this sensor offers six turns for very sensitive and precise adjustments. All the information needed for connecting and setting the sensor is provided on the sensor in the form of a permanent laser inscription. With a range of 50 to 400mm, this unit permits accurate and virtually colour/surface-neutral object detection regardless of the background.
