Rotary encoder for hazardous conditions
Heidenhain's ExN 400 rotary encoders are designed for Potentially Explosive Atmospheres (ATEX) and handle shaft speeds up to 6000 rpm in a temperature range from -20 C to +60 C.
Heidenhain's ExN 400 rotary encoders are designed for Potentially Explosive Atmospheres (ATEX) like printing and the oil and gas industries. The ExN 400 encoders feature a 12mm blind hollow shaft in the new, sturdy design with increased wall thickness and are resistant to shock up to 1500 m/s2 (for 2ms) and vibration up to 100 m/s2. These IP66 ATEX encoders handle shaft speeds up to 6000 rpm in a temperature range from -20°C to +60°C.
They also feature ASIC scanning technology, available with EnDat or SSI interfaces, which allows for improved signal generation, less interpolation error, and more reliable performance in the electronics. Heidenhain ExN 400 encoders are certified for operation in Zones 1 or 21 of equipment group II (above ground applications).
