Overview / Design Principle:
Northstar's DWD38 Harsh Duty Optical Encoder is an Industrial Hollowshaft that operates reliably from -40 to 100°C. The hard anodized finish encoder exceeds IP66/IP67 and NEMA 6 enclosure requirements.
Extremely robust, the DWD38 optical encoders are also available in stainless steel to meet NEMA 4X and 6P requirements. A unique labyrinth double-sealed housing allows operation when regulatory washdown and high pressure steam or caustic chemicals are required.
The DWD38 is a preferred choice as a DrawWorks encoder by the Oil Field industry and is also commonly used in high shoch and vibration environments such as food processing, material handing and packging equipment applications.
It is also available in an intrinsically-safe version certified to ATEX EEX IA IIB T4 used with the appropriate IS barrier.
