The HD20 Harsh-Duty Optical Encoder is ideal for machine applications with corrosive environments that demand stringent wash-downs, including those where high pressure steam or caustic chemicals are needed to meet regulatory requirements. This compact, special-duty encoder is designed to exceed IP66/IP67 and NEMA 6 enclosure requirements with a PPR range through 3600. ATEX certification is also available for intrinsically safe applications (refer to Hazardous Duty HD20).
