Honeywell GAPS Series

The General Aerospace Proximity Sensor (GAPS Series) provides on/off output, and can be configured with an optional health monitoring output to the host system. The technology Honeywell uses in the GAPS Series is considered an improvement on traditional ECKO (Eddy Current Killed Oscillator) topology that previously had been the standard in aerospace applications. The GAPS Series helps to reduce downtime and maintenance costs due to a unique circuit that can detect any internal failures and display a fault output instead of a false positive or false negative.
