LRM 8112 Movement Detector
Technical data
• Sensitivity
level optimised for use in office (or industrial)
applications. Most arm/hand movements
will be detected within the sensitivity area
for radial movements.
pattern nearly circular,
8 m diameter for tangential
movements
6 m diameter for radial movements
• Output
voltage 0 Vdc for active detector (open collector,
normally open.)

Miscellaneous
• Sensitivity
The unit is based on the "passive infrared principle", i.e. it detects
infrared radiated by a moving object.Therefore the practical
sensitivity depends on the combination of characteristics of the
object. It increases with size and temperature (difference with
background), and changes with speed and direction of the moving
object. Sensitivity is maximum for tangential movements and minimal
for radial movements.
