Capacitive sensor works with applied coatings

The sensor has a setpoint (switched) output to indicate presence/absence and its nonlinear analogue output is capable of resolutions of 15nm RMS.

It features a front-panel range indicator to alert the operator to out-of-range conditions, DIN-rail mount electronics and user adjustments for Offset (Zero) and Gain.

A selection of probes provides standard measurement ranges from 0.05 to 6mm.

Offset and Gain can also be controlled with remote potentiometers if the device is enclosed in a control panel.

Sync connectors allow interference-free use of multiple sensors with the same target.

Typical applications for the CPA100, besides basic position monitoring, include production-line part sorting; double-sheet detection in printers or related processes; and monitoring of processes involving nonconductive materials such as films, fabrics and applied coatings, such as adhesives.
