The all-round panel encoder for high radial and axial forces with or without detents / push button at an attractive price level

The MRS panel encoders are the most compact manual setpoint devices in the MEGATRON portfolio with an attractive price level. It is a true all-rounder because of its variety of variants, its solid mechanical construction and its finely tuned selection of components.
Quality at a low price needs not to be a contradiction. This is reflected in its lifespan of 1 million revolutions and an optional shaft seal with IP65 protection. Particularly noteworthy are the high radial and axial forces with which the panel encoder can be operated. The MRS series has been successfully represented on the market for many years, has proven its worth and is used in many applications.

Portfolio allocation

  • Detents / resolutions: Three variants of detents, even without mechanical detent
    There are 3 different mechanical detents of 16, 24 to 32 (audible and tactile) "clicks" with corresponding 4, 6 or 8 pulses per revolution or without mechanical detent (4, 6 or 8 ppr.).
  • Detent torques: Two variants
    The panel encoder is available in two different detent torques: a low one (0.4 ±0.2 Ncm) and a higher detent torque (1.1 ±0.5 Ncm). In the variant without mechanical detent, an operational torque (<0.2 Ncm) remains. If there are significantly higher detent torques required, they can be found in the MRB series.
  • Push button: With or without push button
    The panel encoder has an integrated (or optionally no) push button with travel path of 0.5 ±0.3 mm. Applications which require for the push button a longer travel path please take a look at the series MRT, for short travel path at series MRB. In addition, the series MRB has three variants for the actuating force of the push button.
  • Design: The most compact in our portfolio with six electrical connection types
    With just 15 x 16 x 8.5 mm (L x W x D) at 11 grams, IP65 and its wealth of options - the MRS panel encoder seeks its equals.
  • Power supply / output signal:
    5 V or 3.3 V power supply, open collector output
