Basic Knowledge of Displacement Sensors

What Is a Displacement Sensor

Displacement sensors measure the height and thickness of objects and distances in units of micrometers.
Photoelectric sensors detect the presence of objects, but displacement sensors can accurately measure a distance to object in micrometers.

* There are various types of displacement sensors including contact types, ultrasonic types, capacitive types, and inductive types. This technical guide explains laser displacement sensors, which are equipped with lasers as light sources of optical systems.
