Precise Displacement Detection without Contact: IDEC's MX Laser Sensors
The MX1A and MX1B laser displacement sensors feature high
precision laser beams which can detect infinitesimal displacements within 0.0004"
(10µm). 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 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 for the measured distance between the sensor and the object, depending upon displacement.
The MX1A and MX1B laser sensors can be combined to determine the thickness of an object. Uniform production results when layering materials by providing a precise calculation of the finished thickness. The MX1B also provides a digital readout for easy setup and monitoring. Additionally, IDEC manufactures a fully self-contained laser sensor in our MX1C model.
MX1A/B Features:
- 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" (10µm); 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
MX1C Miniature Laser Displacement Features:
- Detect displacement within 0.002" (50µm); holds tight tolerances and to detect tiny components
- Align visible beam easily when sensing intricate parts in congested installation or dim lighting
- Check infinitesimal displacements, to maintain quality control of vacuum-sealed products
- Install miniature, self-contained sensor where clearances are minimal
- Shape, size, color, and material do not detract from accurate measurement
