Encoder per motori sincroni e asincroni

Space-saving integration into compact servomotors
- The compact design of the rotary encoders of only Ø36 mm and the low construction depth of 26 mm allow installation even in very confined spaces. This allows simple and space-saving integration into compact servomotors with an edge dimension of 40 mm.
Accurate and reliable scanning
- The new optical singleturn scanning with Blue LED technology has very parallel light due to the half wavelength. Thus, the distance between the disc and the diaphragm can be increased up to 3 times. The scanning is thus even more robust to shock, vibrations or shifts due to temperature influence.
Insensitive to interference
- The optical rotary encoders detect and transmit the absolute positional information fully digital. They are therefore substantially more resistant to interference.
Fast and secure data transmission
- An open, non-proprietary digital interface enables fast, secure and convenient data transmission.
Long life span
- The scanning with Blue LED technology allows for a low current and optimal adjustment in case of aging, contamination or temperature influence. Especially at higher temperatures up to 115 °C, the lifetime of the LED and thus the encoder is significantly increased.
Insensitive to contamination
- The three scanning paths, which are over 1 mm wide, are scanned according to the tried and tested Nonius principle and are thus extremely resistant to contamination.

Absolute motor feedback encoder – the precise solution for synchronous servo motors
- Absolute motor feedback encoders detect speed, rotation direction and position at electro motors.
- Their main task in the application is commutation as well as speed and position control at synchronous servo motors.
- The number of steps per revolution defines the resolution. The position is acquired once after setup in a referencing cycle and then permanently retained.
- Absolute motor feedback encoders are optimally harmonized for use at synchronous servo motors both in terms of their mechanical and electrical specifications.

In optical incremental and absolute encoders, blue LED photons with shorter wavelengths and lower penetration depths contribute significantly to improving signal resolution, amplitude, offset, harmonic distortion and jitter performance.
Fewer diffraction and a much sharper image enable encoders with a more compact design and higher resolution, for example, a resolution of up to 10,000 pulses per revolution in a Ø30 mm design.
Blue LED light increases contrast at lower noise levels, improves optical system efficiency and reduces power consumption.
This helps to improve the accuracy and service life of the encoder, especially at high operating temperatures.

The serial BiSS C interface is compatible with the well proven SSI interface (Serial Synchronous Interface).
However, BiSS C offers significant improvements with respect to SSI and supports continuous real-time communication between controllers and sensors.
The application spectrum for BiSS C ranges from production robotics, motor feedback applications and servo drives, motion control and position encoders to CNC machines.
