Explosion-Proof Rotary Encoders
For manufacturing systems in environments where exposure to explosive gases is unavoidable, for example on paint-spray lines, printing machines or silage systems, HEIDENHAIN offers an explosion-proof version of the ROD 420 rotary encoder.
The rotary encoder with a standard housing diameter of 58 mm features an overall length of only 83 mm and complies with the requirements of the directive 94/9/EG (ATEX 100a). The encoder is available with line counts of 250 to 5000. The maximum surface temperature is 120 °C (284 °F). Before the housing attains the maximum permissible temperature, an additional temperature sensor triggers a warning signal to return the system to a safe operating condition.
