Wide Range of Position Sensor Technologies Available

Micronor position transducers can incorporate a broad range of technologies – electromechanical, electrical, optical, magnetic and fiber optic. This article surveys the pros and cons of the various technologies, Sensing The Motion: Rotary Position Sensors – Electromechanical, Electronic and Fiber Optic, Power Transmission Engineering Magazine, August 2010.


MR322 Sensor

MR322 series Incremental Encoder offers 100-360ppr resolution in an industry standard Size 58mm encoder housing. The sensor is ideal for motor speed control and low resolution position monitoring. Like all of Micronor’s fiber optic encoders, the MR322 is a passive sensor which is immune to EMI and is ATEX classified as a “simple apparatus” for use in all manner of hazardous locations and explosive environments. Standard temperate range is -40° to +80°C while the Extended Temperature option can operate over -60°C to +150°C

MR304 Sensor

The MR304 Mini Rotary Encoder is a Size 11, small form factor incremental encoder offering resolution to 512ppr. It is intermountable with resolvers, synchros and conventional electronics-based encoders of the same size.

The MR304 Encoder is a 100% passive sensor which operates entirely in the optical domain. The sensor provides immunity to any electro-magnetic interferences such as lightning, radiation, magnetic fields and other harsh environment conditions. The innovative design provides 100% electrical isolation as well as immunity to high voltages – ideal for harsh environment applications such as feedback for welding robots, measuring anode position in smelters, and monitoring pantograph operation in electric rail applications.

MR302-1 Controller

The MR30X series fiber optic position sensor system is an innovative all-optical design immune to any electro-magnetic interferences such as magnetic fields, lightning, voltage, and other harsh environment conditions. The MR302-1 Controller works with any of the MR30X series fiber optic incremental encoders – rotary or linear. The Sensor is connected to the Controller via an industry-standard 62.5/125μm duplex multimode fiber optic link. The controller keeps track of position and also calculates the RPM or linear speed of the connected encoder. Both position and speed can be read via Modbus/RS485 serial interface, USB or analog output. The analog output can be configured for either ± 10V or 4-20mA output.
