Turck (Germany) has added a variant with a CANopen interface to its QR24 encoder series. The wear-free QR24-CAN variant is equipped for use in mobile machines and industrial applications.
SHORT LATENCY TIMES AS WELL AS A CYCLICAL and event-driven communication are two of the benefits of the CANopen protocol, which is frequently used in this application field. These applications include crane and lifting technology, transport systems, construction machinery, and special machine building. The first pilot customers are already using the contactless encoder with the CANopen interface in the construction machinery and wind power sector. The CANopen port supports bit-rates from 10 kbit/s to 1 Mbit/s according to CiA 301, CiA 305, and device profile CiA 406 3.1. A terminating resistor can be switched in via the CANopen device access.
As with other QR24 models, the sensor and the positioning element of the encoder are fully potted and designed as two independent and fully sealed units that withstand vibration or shocks on the shaft.
Wear-intensive ball bearings or seals that lead to machine downtimes or long maintenance times are not required.
Thanks to its mounting concept using adapter rings, the permanently sealed IP69K encoders can be fitted on standard shafts with diameters up to 20 mm. As well as the stainless steel variants, Turck offers the encoder as multi-turn or single-turn versions with an SSI interface, incremental output, and analog voltage/current output.
