Ex-proof incremental encoders, shaft sizes above 100 mm

With their robust construction and non-contact scanning, these encoders work without wearing down, also when subjected to vibrations, moisture, salt water, dirt, warm or cold temperatures, or shock from strong mechanical forces. These encoders are available with one or more scanning heads, for either redundancy - or to provide different signal types from the same encoder.

Our Ex-proof encoders are certified for use in hazardous areas, zones 1 and 2/22, where an explosive environment may occur. Our Ex certifications include:

  • ATEX (Europa)

  • IECEx (International anerkannte Zertifizierung für Ex-Bereiche)

  • UL-Listung (Nordamerika)


To secure production uptime, add ADS Uptime, which provides monitoring of the encoder functionality as well as tracking of environmental parameters such as vibration, shaft speed, frequency, temperature, and supply voltage to enable condition-based maintenance of your machinery.
