Description

In the development of equipment for use in hazardous environments, selecting the right sensor plays a crucial role. First and foremost, explosion protection of the sensor itself is critical. Additional harsh requirements, such as the ability to withstand severe shock and vibration, and the need for corrosion resistance due to the working atmosphere, are placed on the encoder by the application itself. And, of course, an accurate and high-resolution sensor signal is required in spite of all other demands. Hengstler has incorporated all these requirements into our new, explosion-proof, absolute encoder AX73 with interfaces SSI/BiSS or Profibus. With the addition of AX73, our explosion-proof product range is complete! The optical scanning system of the AX73 encoder provides a highly accurate, high-resolution sensor signal that is also resistant to the strongest external magnetic fields. The connection concept of the AX73 allows the routing of cabling and the final encoder installation to be done in separate steps. This provides significant cost and time savings during installation, as cabling can be done in advance. Emergency servicing can also be done more quickly, due to the ability to simply unplug the encoder cable and plug it into the replacement encoder. With its ATEX and IECEx approvals, the Hengstler AX73 is certified and approved for international use, thus providing the user a global guarantee of safety and reliability in hazardous areas.
