AJS10X Series non-contact Speed & Length Sensor

Non Contact Speed and Length Measurement is revolutionizing manufacturing processes. Old style wheel followers and shaft encoders are problematic due to slippage between the product and contact wheel or shaft. Issues of wear or build-up on the wheel affect calibration. General wear and tear and constant maintenance causing downtime, rejects, defects, and loss through material give away.

The new, smart and uniquely-compact Laser Doppler “Speed and Length” sensor that sets new standards in non-contact speed and length measurements of moving objects and materials in industrial applications.

The AJS10X Series of Speed and Length sensors are Non-Contact. There is No Slip, No Wear, and No Marking of yourproduct. An excellent stand-alone measuring device or fully integrated with your PLC, HMI, or Data Logging Systems.

The AJS10X Series of non-contact laser Doppler speed and length sensors are robustly engineered for harsh metals industry environments, setting new performance standards for hot mills, cold mills and process lines. Their measurement techniques ensure high accuracy without slippage, drift or mechanical wear. The AJS10X Series has no moving parts for maintenance-free operation and delivers repeatable, precise measurement accuracy of better than ±0.05%.

The series includes three lines of models:
AJS100/AJS100R
AJS101/AJS101R
AJS102/AJS102R
AJS103/AJS103R

-Measuring principle-

The SMART AJS10X Series Laser Doppler Speed and Length gauge illuminates the measured surface with an interference pattern created by the intersection of two laser beams. The alternating bright and dark fringe pattern modulates the light scattered by the object with a frequency proportional to the object's speed. This scattered light is detected by a photodiode and the electrical signal is digitally processed to determine the frequency and hence the speed. Object length is then calculated by integrating the speed measurement with respect to time.


The SMART AJS10X Series Laser Doppler Speed and Length gauge extends the measurement principle by using a high-frequency Bragg cell modulator to illuminate the measured surface with a scanning interference pattern, which generates an oscillating light signal even when the object is stationary. The direction of motion is determined by whether the scattered light frequency is higher or lower than the stationary frequency.


-Industry solutions-

The AJS10X Series Smart Sensor is designed for industrial applications and material processing lines; compatible with almost all moving materials including web, plate and sheet.
