Capacitec Proximity Sensors are high-precision electronic measuring devices used for quantifying very small surface variations or changes in displacement. These proximity sensors have a measurement range of +1 millimeter and are accurate to 3 microns. They are well-suited for measurements such as brake rotor dynamic run-out or brake rotor disc thickness variation.

Capacitec Proximity sensors have the following capabilities:
  • Compact size — 0.375” diameter by 0.750” length
  • Very high precision — accuracy to 3 microns
  • Very high sensitivity— +5 volts equals +1 millimeters
  • Robust packaging capable of dynamic brake system measurements at elevated temperatures
