Fiber Optic Linear Incremental Encoder
MICRONOR introduces the world’s first commercially-available MRI Safe linear position sensor system for OEM motion control applications. With 100µm resolution and 50µm accuracy, MR303 Linear Sensor is the ideal solution for medical, MRI, robotic and industrial applications where position and speed must be precisely monitored, and electromagnetic immunity and invisibility is required. The sensor works in conjunction with the MR302-2 OEM Controller which enables the sensor to integrate with conventional PLC controllers and servo drives.
The position sensor is immune to any electromagnetic interference, such as magnetic fields, lightning, high voltage and radiation. Being fabricated from non-ferrous and non-metallic materials, the sensor is also completely transparent to electromagnetic fields. The sensor’s magnetic invisibility also makes it the ideal position sensor for use in Super Paramagnetic Relaxation Measurements in which extremely small magnetic fields are measured. These attributes allow the MR303 sensor to be safely used in and around the MRI bore and does not produce any imaging artifacts.
This high precision linear encoder provides the means for performance enhancements of existing MRI systems as well as enabling new MRI applications and medical devices.

As an incremental system, the absolute position must be set every time the system is powered up. To automate this process, Micronor has developed a special “homing” zone left or right of the film’s active area. In operation, the mechanical system starts up in the “homing” zone and moves towards the first line in the active area. This corresponds to the reference or index position on a conventional encoder. As the sensor moves into the active area, the counter can correctly track the absolute position.
