This is an easy to use, compact GAP-SENSOR with a built-in amplifier.  It provides an output voltage proportional to the distance (gap) between the sensor and target.  It can be used for detecting position, displacement, monitoring vibration, finding metal, rotating speed, and other applications.  An optional extension cable up to 100 meters or a flexible armored cable can be used.




Measuring Range

0~1200mm (when target is iron)


Output characteristics will differ for other target materials like aluminum, stainless steel, or copper.  Contact AEC for assistance.

Sensor Location

For measuring rotational speed, the sensor should be located 1.00.5mm from the target.

Output Voltage

2~5V, 8.2kΩ max (when power supply is +12V DC) Please refer to figure 1 in case of other supply voltage.
