Product description: Optoelectronic manual encoder MRT

With its long travel, the MRT panel encoder is particularly suitable for numerical setpoint applications that require a very clear confirmation from the pushbutton.

If you are looking for a panel encoder with a particularly long pushbutton travel, the MRT is the first choice. The long travel provides safety and helps to prevent incorrect operation, as it prevents an unintended setpoint being transmitted to the evaluation unit.  
The proven MEGATRON quality ensures that the haptic characteristics, such as detent torque and shaft backlash, are subject to only minor changes even after many 100,000 operations..

Portfolio allocation

  • Detents / resolutions: One detent, even without mechanical detent
    There is one mechanical detent of 25 ppr. (25 audible and tactile "clicks") or without mechanical detent (25 ppr.) available.
  • Detent torques: One variant
    The MRT encoder offers a detent torque (0.5 ±0.2 Ncm) and the version without mechanical detent leaves an operating torque (<0.5 Ncm).
  • Push button: With or without pushbutton - pushbutton with longest travel
    The panel encoder has an integrated (or optionally no) pushbutton. The stroke is the longest in the range. If a particularly short stroke is required, we recommend the MRB series.
  • Design:
    Compact with two electrical connection options, up to IP54 on the shaft side. Only the MRS is more compact.
  • Power supply / output signal:
    5 V power supply, TTL output
