Similar to laser micrometers, optical micrometers are thrubeam sensors that measure any object that blocks the light passing from the transmitter to receiver. These sensors are designed without moving parts to provide accurate measurement without regular maintenance. KEYENCE’s optical micrometers come in single-axis, mutli-axis, or 2D models (that create 2D backlit images). Micrometers are ideal for measuring diameter, gap, and width with high accuracy.
