Laser Distance Sensors
The MX1A and MX1B laser displacement sensors
feature high precision laser beams which can detect
infinitesimal displacements of up to 0.0004" (10
microns). These laser sensors provide extremely accurate
results with a linear relationship between analog output and
detected distance. For example, they can detect objects with
very low surface reflection characteristics, such as black
rubber.
The sensor head projects a laser beam to the object. The
diffuse-reflected light from the object's surface is received
as a spot image. This spot image moves from position A to B on
the PSD (position sensitive device). The optical triangle is
used to compute the exact distance between the sensor and the
object.
The MX1A and MX1B laser sensors can be combined to determine
the thickness of an object. Uniform production results can be
obtained when layering materials by providing a precise
calculation of the finished thickness. The MX1B also provides
a digital readout for easy setup and monitoring.
