Overview Industry/Application Specifications Related Info  

Overview / Design Principle:

NorthStar’s HSD37 Extreme Duty Industrial Hollowshaft Encoder accepts up to 1” diameter shafts and operates reliably from –40 to +100°C. Its Hard Anodized finish enclosure exceeds IP66/IP67 and NEMA 6 enclosure requirements.

This robust optical encoder features a double-sealed housing that allows application where regulatory washdown or caustic chemicals are present. Utilization of an advanced Opto ASIC with innovative packaging techniques enables the encoder to operate in high shock and vibration environments.


Features and Benefits:

Mechanical and Environmental

  • Unbreakable code disks for 15 to 5000 PPR
  • Hollowshaft mounting
  • Heavy-duty shaft seals
  • Sealed connector - no soldering

Electrical

  • Cast housing maximizes noise immunity and durability

Applications/ Industries:

The HSD38 extreme duty encoder features simple installation on motor or machine hub shafts.  It is often mounted on the back of motors where encoder feedback is needed in harsh environment applications.  It is ideal for use in corrosive environments that demand heavy washdown protection.

ATEX certification is also available for intrinsically safe applications.
