The WH58MR rotary encoder is a magnetic safety rotary encoder with redundant position detection and hollow shaft, which has been specially developed for use in mobile machines. It can be used in safety-critical applications – up to performance level PLd. Thanks to its particularly robust design, an optionally redundant CANopen or CANopen Safety interface, it is ideally suited for tough conditions in mobile machines. Profile WH58MR:

The optical incremental encoders SPM (increased torque) and SPNTM (reduced torque) are ideal for applications that require high durability and adaptability of the sensor. The optical incremental encoders of the series SPM (increased torque, in IP55 on shaft side) and SPNTM (reduced torque, in IP40 on the shaft side) are characterized by their reliability and long lifespan of more than 100 million shaft movements. The sensor with Ø6 mm or Ø6,35 mm (1/4 ") shaft is fixed by means of central thread. Depending on the version, a resolution of 50…1024 pulses per revolution (360°) is available as TTL or Line Driver output signal. Upon request, further resolutions such as e.g. 1250/2000/2048/2500/4000/4096 and 5000 ppr are realized.

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.

HTx36 encoder - robust, ball bearing, sealed, with solid or hollow shaft. The encoders of the HTx36 series are specially designed for use between simple applications and heavy-duty applications. The contactless encoders in the Ø36 mm metal housing can be precisely matched to the respective area of ​​application thanks to their numerous electronic and mechanical options.

The programmable multiturn sensor ETA25PM can be parameterized by the customer on site to the desired angular measuring range and sense of rotation up to 10,000 times. Only one device for different angles of rotation, sense of rotations direct parametrizable on site. These advantages enable the user the possibilities to set up the ETA25PM multiturn encoder to the requirements of the application on site. Only one angle encoder device for different requirements is needed, which can be parameterized almost as often as required. The ETA25PM measures angles from 0…10° up to 0…72000° (absolute). The ETA25PM is available until protection class IP66 and has a long durability of more than 100 million shaft revolutions. The compact sensor in the 25 mm housing with Ø6 mm or Ø6.35 mm shaft diameter is e.g. optimally suited for use in drive units as position feedback. A variant of the ETA25PM with integrated buttons for angle programming and sense of rotation is available on request.

Thanks to the broadest selection of actuation haptics, the panel encoder can be optimally adapted to the application. The MRB panel encoders are used as manual setpoint devices. Thanks to their's low power consumption, the panel encoder are also suitable for battery-powered applications. Particularly noteworthy is the diverse selection of detent torques and push-button operating forces. Its electrical connection options are also impressive. This variety allows the combination of a great number of operation knobs. For example, an actuating knob with a small diameter in combination with a high detent torque can ensure that the setpoint can only be changed via a higher actuating force. This structure prevents unintentional changes to the pre-set values, for example.

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 hasn't 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. It has proven its worth, and is used in many applications.

The compact MRX50 panel encoders with 50 ppr. prove their precision and quality even after many hundreds of thousands of operations and are customizable on request The panel encoder MRX50 is, in the sum of its characteristics, out of competition. This product design with this fine-stepped 50 detents and push button even under increased environmental requirements (IP65) cannot be found a second time. The robust and precise panel encoder ensures, even after many hundreds of thousands of operations, the largely unchanged quality of its haptic properties, such as the detent and the shaft play. This was confirmed to us by customers who have undergone this sensor comprehensive testing and have opted for the MRX50. This makes the manual encoder the first choice when special emphasis is placed on longevity with consistent quality. MEGATRON customizes the panel encoders on customer request.

Thanks to the True-Power-On function, any angle changes are registered even during a supply voltage interruption and the angle is reproduced exactly as an analogue signal as soon as the supply voltage is restored. The contactless sensor technology works on the basis of modern gradient-based magnetic field evaluation in processor-supported circuit design. This makes the multiturn encoder largely immune to external magnetic fields or changing ambient temperatures. In combination with the precision mechanics, the encoder shows its additional strength compared to magnetoresistive methods. The latter can have weaknesses in voltage-free measured value acquisition. Another special feature of the multi-turn sensor are the signal plateaus at the beginning and end of the range, which prevent sudden signal changes. The electrically effective rotation range of the encoder is 3600°, ex works.
