Absolute Rotary Encoders
Hengstler Acuro Range Overview

An Absolute encoder retains its positional knowledge when electrical power is removed. The Hengstler Acuro range has been developed for robust industrial applications. Enclosures are standard IP65/67, maximum speed is 10,000 rpm continuous. There are solid and hollow shaft versions of every model and a variety of flange mountings.

Hengstler Absolute encoders are mainly 58mm diameter body size (with exceptions) and come with a variety of connection interfaces. The number of turns and angular resolution is coded into data bits typically up to 14 Bit for single turn and 26 Bit for multi-turn. This ability to encode a single turn means that an absolute encoder can be used to give greater resolution than an incremental encoder, but still be used for angular position only. Similarly single turn encoders can be used to determine speed and in some cases acceleration.

Absolute encoders provide data in digital form and originally standarised on a data exchange protocol with a fixed controller, commonly SSi (Syncronous-Serial Interface) and subsequently BiSS. With the advent of "open" fieldbus protocols which enable fast data exchange over networks, it has become common to fit absolute encoders with fieldbus interfaces.

Hengstler absolute encoders are available with a variety of fieldbus interfaces, typically PROFIBUS, DeviceNet, SucoNet, Interbus and CANopen. We show them on this site separately because we believe you are already committed to a particular protocol.
