Export Requirements

Because of high resolutions, exports of the CPA100 may require an export license.

CPA100e

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.

Applications

Production Line Part Sorting

Double Sheet Detection (paper or other nonconductors)

Assembly Process Monitoring: Position, Level, Squareness
