Optical Encoder
The NorthStar HD25 harsh duty optical encoder utilizes a unbreakable code disc, using either a stainless steel or Mylar disc, making it an extremely rugged encoder. The new sophisticated ASIC technology allows for a wider gap enabling it to handle extreme shock and vibration.Northstar's HD25 Harsh Duty Optical Encoder is a compact, Industrial Hubshaft encoder designed to exceed IP66/67 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 washdown environments, including those where high pressures team or caustic chemicals are needed to meet regulatory requirements.The HD25 features 100lb axial and radial bearings, -40 to 100 C temperature range and a unique labyrinth double sealed housing and optional dual "redundant" outputs that are covered by a two-year warranty (one year for bearings). Northstar's traditional quality, reliability and value are built-in every HD20 encoder.Also available in this series is an intrinsically-safe version certified to ATEX EEX IA IIB T4 used with the appropriate IS barrier. Accessory barriers can be supplied with the encoder.
