AE0x Absolute Linear Position Sensors

AE0x Series

Absolute Linear Position Sensors (Absolute Linear Encoders) are designed for measuring and checking displacements, dimensions, run-outs, surface profiles, deformations.

Our absolute linear encoder series includes two models:
AE01 — for hard industrial environments;
AE02— sensors with a built-in display option for laboratory environments.

-Measuring principle-

As compared with incremental sensors, absolute sensors have a number of advantages: the absolute position of the gauge plug is determined immediately after power is on and the necessity of search of the reference mark is excluded.

Also excluded is the probability of accumulation or loss of count pulse signals in case of impacts, vibrations and reverse motion.
