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. Absolute encoder: — Single- or multiturn — Analogue: Voltage/current output, PWM - 12 bit — Digital: SSI, SSI+UVW up to 16 pole pairs, SER, SPI - up to 14 bit — Also redundant Incremental encoder: — A, B, Z also differential A, A/, B, B/, Z, Z/ — OC, TTL, PP signal outputs — Free selection of the number of pulses - up to 1024 ppr. — UVW signals for motor commutation of DC motors up to 16 pole pairs

The FHx58 family is ideally suited for use in the food industry, pharmaceuticals and offshore applications. Encoders are available in two sensor technologies: Optoelectronic: incremental encoder (FHI58) 3D Hall: absolute encoder (FHB58 & FHS58) The high-class mechanical encoder design is independent of the installed sensor technology. High-quality ball bearings allow shaft loads up to 100 N. The dead-space-free sealing and bearings elements guarantee a wobble free shaft operation and ensures that no impurities can infiltrate. The FHx58 can be cleaned with high pressure and steam jets (IP67/P69k). The stainless steel encoder body which is specially surface-treated in combination with PTFE, TPE sealing elements allow that the FHx58 can be used in applications with high hygienic standards. Precisely it is this design which allows to operate the FHx58 also in salty atmospheres permanently or to clean the encoder with cleaning-fluids containing acids and chemicals.

Rotary encoders without integral bearing operate without friction. The two components - the scanning head and the scale disk, drum, or tape - are adjusted to each other during assembly. The benefits are: Large diameter of hollow shaft For high shaft speeds No additional starting torque In addition to the system accuracy, the mounting and adjustment of the scanning head normally have a significant effect on the accuracy that can be achieved with rotary encoders without integral bearings. Of particular importance are the mounting eccentricity and radial runout of the measured shaft. The inductive rotary encoders ECI/EQI 1300 are mechanically compatible with the photoelectric encoders ExN 1300: the shaft is fastened with a central screw. The stator of the encoder is clamped by an axially tightened screw in the location hole.

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.

In rotary encoders with integral bearing and stator coupling, the graduated disk of the encoder is connected directly to the shaft to be measured. The scanning unit is guided on the shaft via ball bearings, supported by the stator coupling. During angular acceleration of the shaft, the stator coupling must absorb only that torque resulting from friction in the bearing, thereby minimizing both static and dynamic measuring error. Moreover, the coupling mounted on the stator compensates axial motion of the measured shaft. Other benefits of the stator coupling are: Simple mounting Short overall length High natural frequency of coupling Hollow-through shaft possible

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.
