Edited by the Manufacturingtalk Editorial Team on 14 August 2007

Passive encoder uses no internal
electronics

A totally passive encoder uses no electronics within the sensor and is therefore usable in stressful environments not suited for conventional electronic-based encoders.

US patent ofice has awarded Micronor patent number 7,196,320 for its ZapFREE Fiber Optic Rotary Encoder System The patent recognizes Micronor's innovative wavelength division multiplexing approach which produces a totally passive encoder utilizing no electronics within the sensor - and therefore deployable in stressful environments not suited for conventional electronics-based encoders

The Micronor encoders meet ATEX requirements as 'simple apparatus' and are certified for use in hazardous environments.

Customer applications now range from aerial cable cars to electric trains; from mines to steel mills to oil rigs.

The sensors are offered in 100-1024ppr resolutions as well as industry-standard shaft or hollow shaft configurations.

The MR3XX sensors mechanically mount like any conventional rotary encoder - then connected by a simplex fiber optic link to a MR310 Remote Encoder Interface (REI) module.

The versatile REI module offers an array of standard interfaces (quadrature, serial 4-20mA and , +/-10V, etc.) that ensures connectivity with all major motor drive, motion control and PLC systems. Request a free brochure from Micronor ...
