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.
Applications
Glue Detection (or other deposited material)
Double Sheet Detection (paper or other nonconductors)
Assembly Process Monitoring: Position, Level, Squareness
Specifications
Typical specifications. Actual values depend on probe and calibration.
