QR24 contactless encoders in stainless steel

August 2014 Sensors & Transducers

Turck now offers a robust stainless steel variant of the contactless, inductive encoder QR24. The new EQF24 varsion of the wear-free encoder is suitable for use in the food industry as well as in other applications. With the V4A stainless steel housing and the active surface of PA12-GF30 plastic, the device withstands even aggressive chemicals and high pressures in the cleaning process. The new EQF24 is available with incremental output and SSI interface.

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. The QR24 series has the edge over both optical and magnetic encoders.

Thanks to its intelligent mounting concept using adaptor rings, the permanently sealed IP69K encoders can be fitted on all standard shafts with diameters up to 20 mm. As well as the new stainless steel variants, Turck also offers the encoder as a multiturn or singleturn version with an SSI interface, incremental output and analogue voltage/current output.
