Optical Encoder

The NorthStar HSD25 harsh duty Optical Encoder utilizes an 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 HSD25 Harsh Duty Industrial Hubshaft Optical Encoder accepts up to 0.78" diameter shafts and operates reliably from -40 to 100°C. The hard-anodised 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 wash down and high pressure steam or caustic 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 is also available in an intrinsically safe version certified to ATEX EEX IA IIB T4 used with the appropriate IS barrier.
