Micronor: MRI Safe Linear Encoder for Medical Applications

July 9, 2015

The MR303 Linear Sensor is for medical, MRI, robotic and industrial applications where position and speed must be precisely monitored, and electromagnetic immunity and invisibility is required.

The sensor features 100 µm resolution and 50 µm accuracy and works in conjunction with the MR302-2 OEM controller which enables it to integrate with conventional PLC controllers and servo drives. The unit is immune to electromagnetic interference such as magnetic fields, lightning, high voltage and radiation, and is completely transparent to electromagnetic fields, which makes it suitable for use in super paramagnetic relaxation measurements in which extremely small magnetic fields are measured. It provides the means for performance enhancements of existing MRI systems as well as enabling new MRI applications and medical devices. Applications include MRI cradle position monitoring, MRI robots and MRI phantom training organs. The controller features both A/B quadrature outputs and Modbus RTU serial interface for transparent integration into the user's application. A discrete HOMING Input is used for internally presetting the absolute position while a discrete STATUS Output provides the direct means of monitoring the encoder's system health. The controller contains a feature-rich Modbus communications protocol for ease of integration into the user's control system.
