Fiber Optic Incremental Encoder
Includes MR343 Linear Encoder
The MR340-1 Controller is a rebranding, part number change only
of the original MR302-1 DIN Controller. Any references to MR302-1
are applicable to the MR340-1 and vice versa. In addition, the former
MR303 Linear Encoder is now the MR343, and the former MR304
Mini Rotary Encoder is now the MR341.
The core dual wavelength 850nm/980nm optical technology of the
MR302 series replaces the 850nm/1300nm technology of the earlier
MR320 series, becoming the MR340 series. For more information on
the MR340 series Controller and Encoders and their compatibility
with earlier models, please consult Application Note AN127.

    MICRONOR AG MR340-1 DIN Rail Module Controller How To Install the MR343 Linear Encoder Film Mounting and Handling With MR343 Although the film positioning within the sensor slit is not critical, it should be mounted in such a way that it is as parallel to the sensor pick-up head as possible. Ideally the film should be mounted so it is perpendicular to the sensor head and always lay against one side of the slit.

  • Page 20: Figure 19. Td5334 Encoder Filmstrip Dimensions

    MICRONOR AG MR340-1 DIN Rail Module Controller Positioning the film affects the ultimate performance of the system. Apply just enough pull to the film so as it is stretched at all times. Too much pull will increase pressure on the read surface and may lead to high wear of the film.
