    HD25 Hazardous Duty Optical Encoder

    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-down environments, 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 HD25). Application: Top Drives, Iron Roughnecks, Wireline, Logging, Coiled Tubing, Cementing and Fracing/Blenders; Converting Machinery; Material Handling; Packaging Equipment; Pickling Equipment; Processing Equipment; Length measurements; Motor and drive speed feedback; Cut-to-length (textile, paper, wood, metal, rubber, plastics, etc.); PLC’s and electronic counters.

    Plastic encoder coupling

    Shaft encoders must be protected against excessive mechanical stresses, which occur whenever there are angular, axial, or radial misalignments between the machine and shaft encoder shafts. Our flexible couplings can compensate for this within limits.
