Statistic/User tracking
Storing behavioral user data for analytical purposes and statistics.
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.
Applications
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.
Technology
LED bleue pour une compacité, une résolution et une durée de vie accrues
Dans les encodeurs optiques incrémentaux et absolus, les photons LED bleus à longueurs d'onde plus courtes et à profondeur de pénétration plus faible contribuent de manière significative à améliorer la résolution du signal, l'amplitude, le décalage, la distorsion harmonique et les performances de gigue.
Moins de diffraction et une image beaucoup plus nette permettent aux codeurs de conception plus compacte et d'une résolution plus élevée, par exemple une résolution allant jusqu' à 10 000 impulsions par tour dans une conception Ø30 mm.
La lumière bleue LED augmente le contraste à des niveaux de bruit plus faibles, améliore l'efficacité du système optique et réduit la consommation d'énergie.
Cela permet d'améliorer la précision et la durée de vie du codeur, en particulier à des températures de fonctionnement élevées.
BiSS C
L'interface série BiSS C est compatible avec l'interface éprouvée SSI (Serial Synchronous Interface).
Cependant, BiSS C offre des améliorations significatives par rapport à SSI et prend en charge la communication en temps réel et en continu entre les contrôleurs et les capteurs.
Le champ d'applications pour les interfaces BiSS C va de la robotique en production, du feedback moteur avec des servomoteurs, du contrôle de mouvement de position aux machines CNC.
