The optical HSD25 hollow shaft rotary encoder with up to 19.05 mm shaft diameter will work reliably within a temperature range from -40°C to +100°C. This type of rotary encoder with its hard anodized housing outlet exceeds the requirements of IP66/IP67 nd NEMA 6. By employing a state-of-the-art opto-ASIC, the rotary encoder is resistant to shocks and vibrations.
The HSD25 rotary encoder can easily be installed in conjunction with motors and thus provides reliable feedback signals even in tough ambient conditions. The HSD25 series of rotary encoders also includes intrinsically safe ATEX variants for use in potentially explosive atmospheres.
NorthStar’s HSD25 Harsh-Duty Optical Hub Shaft Encoder accepts up to 0.75″ 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 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 when used with the appropriate IS barrier.
