Distance & Displacement Sensors MX1A/MX1B

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.

• Detect slight differences in levels to verify quantity of thin, stacked sheets, such as paper or plastic
• Calculate thickness to maintain quality on high-speed webs
• Detect displacement within 0.0004" (10 microns); holds tight tolerances during precision placement using robotics
• Use small beam for precise detection of tiny, intricate parts
• Use high-powered beam to detect material which ordinarily absorbs laser light, such as black rubber
• Operate safely with delayed laser, remote interlock, power key switch, and laser LED on sensor head
