Ex-proof XHI 841 incremental encoder

The ATEX- and IECEx-certified incremental encoder model 841 in the 800 series uses High-Current HTL (HCHTL) signals for long distance transmission.

For model 841, there is the option to order ADS Classic, an advanced diagnostic system that will provide a warning and early detection of pending faults. ADS Classic is included in the product’s certification for hazardous locations. Thanks to this, condition monitoring can be achieved for encoders in Ex zone 1/21.
