Khushali Enterprise

The HD20 Harsh-Duty Optical Encoder is a compact heavy-duty encoder designed to
exceed IP66/IP67 and NEMA 6 enclosure requirements. It is also available in stainless steel
that exceeds NEMA 4X and NEMA 6P requirements and is ideal for stringent wash down
environments, including those where high pressure steam or caustic chemicals are needed
to meet regulatory requirements.

The HD20 features max. 440N Axial and Radial Bearings, −40° to +100°C temperature range
and unique labyrinth double-sealed housing, and optional dual "redundant" outputs and is
covered by a two-year warranty (one year for bearings). NorthStar's traditional quality,
reliability and value are built-in to every HD20 encoder.
Also available in this series, is an Intrinsically Safe version certified to ATEX EEx ia IIB T4 when
used with the appropriate IS Barrier. Accessory barriers can be supplied with the encoder.

APPLICATIONS:

The HD20 Harsh-Duty Optical Encoder is ideal for machine applications with corrosive environments
that demand heavy washdown protection. This compact, special-duty encoder is
designed to excede IP66/IP67 and NEMA 6 enclosure requirements with a PPR range
through 3600. ATEX certification is also available for intrinsically safe applications.

The NorthStar brand Series HSD35 Sealed Hollowshaft encoder is designed for easy installation
on motor or machine shafts. Its hollowshaft design eliminates the need for a flexible
shaft coupling, mounting bracket, flower pot, or flange adapter. This not only reduces the
installation depth, but also lowers total cost.
The Series HSD35 Sealed Hollowshaft is equipped with an unbreakable disk that resists
contamination and meets the demands of the most severe shock and vibration generating
processes. Its floating shaft mount and spring tether eliminate bearing loads and flexible
shaft couplings to eliminate wear and maintenance.
Series HSD35 has complete electrical protection from overvoltage, reverse voltage, and
output short circuits. In addition, the Series HSD35 is not only electrically & thermally isolated,
but also environmentally sealed with shaft seals at both ends.

Applications:

The HSD35 sealed hollow shaft encoder is ideal for motor and machine applications at resolutions
to 2500 PPR. Choice of stamped metal or swivel rod tether provide flexible mounting
for a wide varity of installations
