Displacement sensor

LF44 series


Working principle based on laser triangulation method, the LF44 displacement sensor has an enclosure dimension of 17.8mm thickness x 44mm height x 31mm long. The laser emitter emits laser light onto the surface of the object being measured through lens, and the reflected light is received by an internal CCD linear camera through receiver. Based on the position change of the light spot, the digital signal processor calculates the distance between the sensor and the measured object. This method is suitable for high-precision, short-range measurements.
