Overview Industry/Application Specifications Related Info  

Overview / Design Principle:

Northstar's HSD25 Harsh Duty Industrial Hubshaft Optical Encoder accepts up to 0.78" diameter shafts and operates reliably from -40 to 100°C.    The hard anodized finish encoder exceeds IP66/IP67 and NEMA 6 enclosure requirements.

This robust encoder is also available in stainless steel to meet NEMA 4X and 6P requirements and its sealed housing allows the encoder to be operated when regulatory washdown and high  pressure steam orcaustic chemicals are required. Utilization of an advanced Opto ASIC with innovative packaging techniques enables the encoder to operate in high shock and vibration environments.

The HSD25 heavy duty optical encoders are also available in an intrinsically-safe version certified to ATEX EEX IA IIB T4 used with the appropriate IS barrier.


Features and Benefits:

Mechanical and Environmental

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

Electrical

  • Cast housing maximizes noise immunity and durability

Applications/ Industries:

The HSD25 harsh 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.  Available housing options make it ideal use in corrosive environments that demand heavy washdown protection.

ATEX certification is also available for intrinsically safe applications.
