KD-5100 Eddy Current Sensor

Differential resolution to a nanometer

About the KD-5100 Eddy Current Sensor

KD-5100 Differntial Super High-Precision System: The hybrid for the KD-5100 is manufactured to MIL-H-38534. MIL-SPEC components are utilized throughout the electronics module wherever possible. The KD-5100 features rugged construction with a mean time between failures of better than 55,000 hours in a tactical environment, 238,000 hours in a space flight environment. The small package size of the KD-5100 (just 2 x 2.12 x 0.75 inches thick) makes this system ideal for applications where space is a limiting factor.
