Magnetic Distance Measuring Systems

A sensor moves in proximity to a magnetic tape to produce a digital signal. This signal is then processed to relate to position along the axis. This non-contact technology provides a maintenance free solution to most linear or angular, absolute or incremental position measurement.

Available in:

Incremental Version

Provides direct linear and rotary position feedback normally with reference to a datum on the axis. The rotary version offers an alternative to optical encoders where on shaft mounting without maintenance or high environmental IP rating may be required.

Available with:

• Resolution to from 10 to 0.0002 mm
• Digital Outputs either Push Pull or TTL
• Lengths upto 160 metres possible
• To IP67 Protection
• Operating Speeds upto 25 metres per second
• Low Cost Low Resolution Versions

And

Absolute Version

The first absolute magnetic linear encoder available using non contact digital technology. A magnetic sensor passes along the magnetic tape to produce upto 20 million unique digital steps across its travel. This information is processed and can be then transmitted by parallel. SSI(Synchronous Serial Interface), Profibus or CAN Bus communication. Suits arduous industrial applications with forces in excess of 30G allowed and protected to IP67.

Available with:

• Resolution to from 1 mm to 0.001 mm
• Lengths upto 163 metres
• Accuracy to 0.01 mm
• Upto IP67 Protection as Standard and is therefore unaffected by dust, dirt or fluid ingress
