Precise – Robust – Reflectorless:
Measures distances with millimetre accuracy
Precisely defines positions
Detects movements
The KHU-LMC-J-0040-1-CC82 is an opto-electronic
distance measuring module for industrial applications. The
module operates on basis of non-contact comparative
phase measurement with amplitude modulation. The
Laser diode (cw operation) has a divergence of 0.6 mrad
for measurement with pinpoint accuracy. The measured
result is available on the RS 232 / RS 422 data interface.
A digital switching output, an analogue 4..20mA output
and optional a Profibus output is also available. The
sensor alignment can be easily achieved with the help of
the red pilot laser. The Measuring range is on any
natural surface between 0,2 to 30m, for 30 to 100m
depends it on the surface reflectivity coefficient (f.e.
concrete 30%, white paper 90%) and for more than 100
% we can deliver special plastic reflectors with a very
high reflectivity coefficient of 2000%.
Features:
Laser class 2 for eye safe operation
