Motor feedback encoder also with 1:3 cone

The ACURO AD37 absolute encoder from Hengstler records position data reliably and precisely even at high speeds. Now the encoder is also available in a version with a 1:3 cone: this means that manufacturers of standard servo motors can also easily integrate it into their drives.

The main field of application for the ACURO AD37 is highly dynamic, safety-critical applications. The encoder is optimally equipped for the strict requirements in this area: Firstly, it operates extremely precisely and dynamically even at speeds of up to 12,000 min-1. With an absolute accuracy of ±36 angular seconds and a repeatability of less than ±10 angular seconds, it also ensures the highest control performance. On the other hand, the AD37 is certified according to SIL 3 (PLe, category 3) and offers a resolution of 20 bits in single-turn and 12 bits in multi-turn operation. These features and its dual-channel redundant design predestine the encoder for applications with high safety and accuracy requirements.

The ACURO AD37 is not only extremely accurate, but with a depth of only 29 mm it is also the most compact multiturn motor feedback encoder in its class. This means that the encoder fits into the tight installation spaces of servo motors. In addition to its precision and very compact design, the AD37 is also characterised by a high degree of robustness. In continuous operation, the encoder reliably withstands not only temperatures of up to 120 °C, but also vibrations of up to 300 m/s2 (10...2,000 Hz).

Another striking feature of the absolute encoder is its excellent signal quality: it enables a much "smoother" control of drives than with comparable encoders and thus also very energy-efficient operation. The high signal quality also ensures loss-free transmission of position and temperature data at 10 MBaud over a distance of up to 100 m.

With the new version of the ACURO AD37 with 1:3 cone, Hengstler has once again extended the range of applications of its proven multiturn absolute encoder. Manufacturers of standard servo motors no longer have to make complex modifications to their drives in order to be able to use the encoder. It can now simply be plugged onto the motor shaft via the cone.
