Laser Sensor LMC-J-0030-XLaser distance detector LMC-J-0030 of Kempf GmbH

Laser distance detector mit 3 relay outputs

For collision avoidance and warning

Laser sensor LMC-J-0030-x is an opto-electronic distance detection module for industrial applications. The device uses a contactless measuring technique based on comparative phase measurement and amplitude modulation. The sensor world with a cw-Laser diode. The transmitting power is ≤ 1 mW and therefore achieve Laser class 2. Laser divergence  conducts 0.6 mrd and allows a measurements in pinpoint accuracy.

The sensor is easy to programming und therefore offers three free selectable break points over the complete measuring range. The necessary „teach-in“ buttons are situated on the back panel of the sensors hidden under screw-fxed cover plate. Parametrizable are three relay switching outputs. An additional fourth relay in the sensor switches off during measurement, in case of a hardware failure, fall of potential or a measuring error.

There are three LEDs placed on the back panel of the sensor (3x yellow, 1x red), visualizing the three single conditions relating to the current switching value. The fourth red LED is for visualizing errors.


Features of the LMC-J-0030-X:

  • Non-contact distance detecting with the help of
    3 switching outputs, f.e. für collision avoidance
