Proximity Sensors and Displacement Sensors

Proximity sensors are often used for simple presence/absence detection – this is why they are often called proximity “switches.” But some applications require higher performance measurement. Applications where the difference between present and absent may only be a few microns require higher resolution sensors than a typical proximity switch. The CPA100 can resolve a target’s position to less than 50 microns and do so at up to 15 kHz. It also provides a nonlinear analog output to provide feedback proportional to the target’s position.
