The North Star HSD44 series rotary encoders that have proven themselves in heavy-duty rail operation are designed for extreme working conditions. The devices provide 1024 pulses per revolution (PPR) via a tough, stainless steel disc in conjunction with a specially-developed optical sensor. The large slot in the sensor reduces the sensitivity of the motor bearings to impact, vibrations and wear. The HSD44 has been specifically designed for attachment to the end of a motor. Adapter plates are available for popular motor types. On request, we can manufacture adapter plates for any appropriate application. The HSD44 is ideally suited to controlled motor feedback in heavy-duty drives and hybrid-drive vehicles. It has been tried and tested in the field and is reliable in heavy-load applications and industrial environments.
Even electric motors in the harshest environment require feedback to ensure smooth speed control. In the past, engineers have applied encoders and sensors designed for standard industrial environments into these extremely harsh environments, impacting system reliability and increasing life-cycle costs. Hengstler has the solution. The heavy rail proven NorthStar HSD44 series optical encoder was designed to be a survivor. This anodized aluminum encoder can survive high levels of shock and vibration, wide temperature extremes, and operating environment contaminants. The HSD44 can withstand the harshest outdoor environments and the toughest industrial applications.
