Thanks to the widest selection of actuation haptics, the panel encoder can be optimally adapted to the application

The MRB panel encoders are used as manual setpoint device. Thanks to its low power consumption, the panel encoder is also suitable for battery-powered applications. Particularly noteworthy is the diverse selection of detent torques and push button operating forces. Also impressive are its electrical connection options.
This variety allows the combination with a variety of operation knobs. Thus, a small-diameter operating knob in combination with a high detent torque can ensure that the desired value can only be changed by a higher operating force. For example, this combination counteracts with unintentional change of present values. On the other hand, an operating knob with a larger diameter can provide the desired smooth operating feel, because a higher leverage effect acts on the fulcrum.

Portfolio allocation

  • Detents / resolutions: Two variants of detents, even without mechanical detent
    There are 2 different mechanical detents 16 or 25 ppr. (16 or 25 audible and tactile "clicks") or without mechanical detent (16 or 25 ppr.) available. If a lower resolution is required, this can be found again in the MRS series.
  • Detent torques: Four variants - largest selection
    The MRB rotary encoder offers the widest selection of detent torques. In four variants from a smooth to a very high detent torque (0.4 ±0.1 Ncm / 0.6 ±0.2 Ncm / 10.5 ±0.35 Ncm / 16 ±0.5 Ncm). In the variant without mechanical detent an operational torque (<0.4 Ncm) remains.
  • Push button: With or without push button – in three actuating force variants and short travel path
    The panel encoder has an integrated (or optionally no) push button. The travel path is the shortest in the portfolio. To meet the haptic and / or safety-related needs, there are three options for the operating force of the push button to choose from. If a particularly long stroke is required, we recommend the MRT series.
  • Design:
    Compact in four electrical connection variants, shaft side up to IP55. More compact is only the MRS.
  • Power supply / output signal:
    5 V or 3.3 V power supply, TTL output
