Series HD20 Optical Encoder Series HD20 Optical Encoder

Quick Specs…

  • Single or dual output
  • Optional high current line driver
  • ATEX certification available for intrinsically safe application
  • High resolution unbreakable disk
  • Industrial Duty Latching Connector
  • NEMA 4 / IP67 Rated
  • Nickel or stainless steel housing available
  • Two Year Warranty

Overview / Design Principle:

Northstar’s HD20 Harsh Duty Encoder is an Industrial Hubshaft Encoder that is a compact, heavy-duty 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 HD20 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 to 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.

Features and Benefits:

Mechanical and Environmental

  • Unbreakable code disks for 1 to 3600 PPR
  • Flexible mounting
  • Heavy duty shaft seals
  • Sealed connector – no soldering

Electrical

  • Cast housing maximizes noise immunity and durability

Applications/ Industries:

The HD20 harsh duty 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.
