New Capacitive Proximity Switch Has High-Resolution Analog Output And User Adjustments

St. Paul, MN USA, February 15, 2011

The CPA100 Capacitive Sensor from Lion Precision has a setpoint (switched) output to indicate presence/absence like a typical proximity switch, but the nonlinear analog output is capable of resolutions as low as 15 nm RMS (150 nm p-p). The new sensor features a unique 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 6 mm. 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.
