The ECL202 eddy-current sensor system delivers exceptional resolutions, down to 10nm, and bandwidths up to 15kHz. The electronics of the ECL202 are based on the latest FPGA digital technology, delivering excellent noise immunity and very high stability. The system provides a linear analogue voltage output (0 - 10 Volt) proportional to changes in the target position and a digital (switched) output with a user programmed switching threshold.
