Precision Analog Out Capacitive Proximity Sensor
The CPA100 is a high-precision capacitive, noncontact proximity switch with a nonlinear analog output. The analog output provides linear position sensor feedback while the precision repeatable switched output alerts operators and systems to conditions. Rectangular and cylindrical probes provide options for a variety of applications. Vacuum compatible systems are available.

Because of high resolutions, exports of the CPA100 may require an export license.
The CPA100e has different resolution specifications and can ship without export license delays.
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.
