The intrinsically safe optical ATEX hollow shaft encoder ISD25 with up to 19.05 mm shaft diameter operates reliably in the temperature range from -40 °C to +100 °C. This encoder type with hard-anodized housing design exceeds the requirements of protection class IP66/IP67 and NEMA 6. By using an OptoASIC of the latest technology, the encoder is insensitive to shock and vibration. The encoder type HSD25 can be easily installed on the motor and thus enables reliable feedback signals under harsh environmental conditions.
