Description
The HD25 Harsh-Duty Optical Encoder is identical to the HD20 but larger in size and capable of a higher resolution. It 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 5000. ATEX certification is also available for intrinsically safe applications.
