Product description: Optoelectronic Manual Encoder MRX25

MRX25 panel encoder with 25 pulses and pushbutton is suitable for custom detent torques.

The MRX25 panel encoders offer a unique combination of 25 ppr and IP65 protection. The high quality of the range has been confirmed by our customers, who have subjected the encoders to extensive testing before incorporating them into their applications. The result of the tests was consistently the same: even after many hundreds of thousands of operations, the haptic characteristics, such as detent torque and shaft backlash, have changed only insignificantly. The electrical values at the output of the sensor were exactly the same as on the first day. This makes the panel encoder the first choice when it comes to longevity and consistent quality.
MEGATRON customizes the panel encoders to customer requirements. An individual product adaptation could be a specific shaft geometry, a customized detent torque or push button force, as well as special electrical connection variants.

Portfolio allocation

  • Detents / resolutions: One detent
    A mechanical detent of 25 ppr. (25 audible and tactile "clicks") is available.
  • Detent torques: Two variants
    The MRX25 panel encoder offers two detent torques: 0.4 ±0.2 Ncm or 1.2 ±0.5 Ncm. Customized detent torques are available on request.
  • Push button: With or without push button
    The panel encoder has an integrated (or optionally none) pushbutton. The travel of the MRX25 pushbutton is in the middle of the range. For applications requiring a longer button travel, please refer to the series MRT, for short travel the series MRB
  • Design:
    Compact with four electrical connection options, up to IP65 on the shaft side. Only the MRS is more compact.
  • Power supply / output signal:
    5 V or 3.3 V power supply, TTL output
