HEIDENHAIN unveils a new line of rotary encoders for Potentially Explosive Atmospheres (ATEX). Many industries – such as oil and gas, printing, and silage -- operate in such environments. The ExN 400 encoders feature a 12mm blind hollow shaft in the new, sturdy design with increased wall thickness. The ExN 400 encoders are resistant to shock up to 1500 m/s2 (for 2ms) and vibration up to 100 m/s2.
These IP 66 ATEX encoders handle shaft speeds up to 6000 rpm in a temperature range from -20°C to +60°C. The HEIDENHAIN ATEX encoder family already includes solid shaft incremental or absolute encoders of the ROx 400 series. Absolute ATEX encoders will now feature ASIC scanning technology, available with EnDat or SSI interfaces. ASIC technology allows for improved signal generation, less interpolation error, and more reliable performance in the electronics. HEIDENHAIN ATEX encoders are certified for operation in Zones 1 or 21 of equipment group II (above ground applications).

HEIDENHAIN is represented all over the world today, mostly by wholly owned subsidiaries. Sales engineers and service technicians support the user on-site with technical information and servicing.
The high quality of standard of HEIDENHAIN is documented through certification in the ISO 9001 quality systems model and by authorization as German Calibration Service (DKD) inspection station for units of length and angle. Long product service life and recyclable designs on the one hand and careful use of resources and optimized energy consumption on the other are preconditions for the Environmental Declaration in compliance with ISO 14001.
The high quality of HEIDENHAIN products depends on special production facilities and measuring equipment. Masters and submasters for scale manufacturing are produced in a clean-room building, with special measures for temperature stabilization and vibration insulation, built especially for this purpose. The copying machines and the machines required for the manufacture and measurement of linear and circular graduations are also developed and built by HEIDENHAIN.
