Panel encoder MRX25 with 25 pulses and push button are suitable for individual detent torques according to customer requirements

The panel encoders MRX25 stand for the unique combination of 25 ppr. and IP65. The high quality of the series was confirmed by our customers, who subjected the encoder to extensive testing before adopting the manual encoder in their application. The result of the tests was consistently the same: even after many hundreds of thousands of operations, the haptic properties, such as the detent torque and the shaft play have changed only insignificantly. The electrical values could be received precisely at the output of the sensor as on the first day. This makes the panel encoder the first choice when special emphasis is placed on longevity with consistent quality.
MEGATRON customizes the panel encoders on customer request. An individual product adaptation could be specific shaft geometry, custom detent torque or push button force as well as special electrical connection variants.

Portfolio allocation

  • Detents / resolutions: One detent
    There is one mechanical detent of 25 ppr. (25 audible and tactile "clicks) available.
  • Detent torques: Two variants
    The MRX25 panel encoder offers two detent torques: 0,4 ±0,2 Ncm or 0,8 ±0,2 Ncm. On request, we implement individual detent torques according to customer requirements.
  • Push button: With or without push button
    The panel encoder has an integrated (or optionally no) push button. In the portfolio comparison, the travel path of the MRX25 push button is in the midfield. Applications which require a longer travel path for the push button please take a look at the series MRT, for short travel path at series MRB.
  • Design:
    Compact in four electrical connection variants, shaft side up to IP65. More compact is only the MRS
  • Power supply / output signal:
    5 V or 3.3 V power supply, TTL output
