Linear position sensor for OEM motion control applications
Micronor’s MR303 linear position sensor system is designed for OEM motion control applications such as medical, MRI, robotic, and industrial applications where position and speed must be 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 PLC controllers and servo drives. The position sensor is designed to be 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 transparent to electromagnetic fields.
The linear encoder 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 system uses a coarse wavelength division multiplexing technique incorporating two lasers representing the A and B quadrature signals. An encoder film strip passes through the MR303 optical read head, modulating the A and B optical signals. The remote MR302-2 Controller provides both the optical input to the MR303 Sensor and processes the modulated optical return signal.
