Hengstler ACURO AX73 optical encoder

The Hengstler ACURO AX73 optical encoder offers attributes such as ease of installation, high precision and compact dimensions.

Explosion protection is the first consideration and the product carries ATEX and IECEx certification for gas and dust explosion-proof requirements. The optical encoder is suitable in applications such as winches, cranes, drills and other oil and gas industry equipment, as well as at paint plants, petrochemical facilities, bottling plants and grain mills.

The product allows the routing of cabling and the final encoder installation to be done in separate steps. This provides cost and time savings during installation, as cabling can be done in advance. Emergency servicing can also be completed more quickly, resulting from the ability to simply unplug the cable and connect it to the replacement encoder.

Another ease-of-maintenance feature includes the use of just two screws for the connection hood. Special patented screws are deployed on the product to protect against dust, water and corrosion.

The optical scanning system provides an accurate, 22-bit resolution sensor signal for wherever precision or smooth speed regulation is necessary. It is resistant to shock, vibration and external magnetic fields. In addition, the unit provides users with IP67 protection class rating for the stainless steel housing and offers an ex-related ambient temperature range of -40 to +70°C.

The product has a housing diameter of 76 mm and can be ordered with SSI, BiSS-B, BiSS-C and Profibus interfaces.

The product offers a mounting system with integrated cable.
