The MX1C is a self contained laser displacement sensor. Featuring a small size and high resolution of 50 microns ( 0.002" ) , the MX1C is perfect for small mounting areas with delicate applications. The MX1C is easy to align with its visible Red laser.The MX1C offers a 4-20mA analog output, and, a discrete transistor output for displacement determination.
The MX1C utilizes triangulation to determine object displacement. 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.
