Miniature encoder for mobile equipment

June 2017 Sensors & Transducers

Turck’s compact and wear-free Ri360-QR20 miniature encoder is especially designed for use in mobile machinery. The new encoder series with IP68/IP69K protection exceeds the e1/E1 requirements and comes in a compact 71 x 64 x 20 mm housing. It is based on the contactless resonator measuring principle. The housing fully surrounds the positioning element and provides it with full protection from the outside. Alternatively, the positioning element can also be positioned above the sensor. This design principle not only reduces the planning work for the designer, but also offers mechanical protection, as well as protection from dust and moisture. The housing is also permanently sealed. Even the often problematic potential points of leakage such as LED lenses are eliminated since the QR20 uses a translucent plastic.

The encoder offers interference immunity of 100 V/m and is protected from line-conducted interference according to DIN ISO 7637-2 or SAE J113-11, the so-called load dump. Salt spray or rapid temperature changes, as well as diesel, kerosene or vibrations have no effect on the device. With a temperature range from -40 to +85°C there are virtually no climatic conditions that could be critical for the QR20. The device offers 12-bit resolution on the output side, corresponding to around 0,09 degrees. The output signal ranges from 0,5 to 4,5 VDC. If the sensor does not detect a positioning element, the value jumps to 5 V.

The user can choose between four connection types: German plug connectors, AMP plug connectors, M12 plug connectors or open ended cables. The positioning element supplied with the device allows versatile connection to different shaft diameters. With the new QR20 encoder Turck customers can choose from seven preset angle variants: These are 20°, 40°, 60°, 90°, 120° and 240°, as well as 360°.
