Even electric motors in the harshest environmentsrequire feedback to ensure smooth speed control. Inthe past, engineers have applied encoders and sensorsdesigned for standard industrial environments intothese extremely harsh environments, impacting systemreliability and increasing life-cycle costs. NorthStar, thefirst name in heavy-duty encoders, has the solution.The heavy rail proven NorthStar HSD44 series opticalencoder was designed to be a survivor. This anodizedaluminum encoder can survive high levels of shock andvibration, wide temperature extremes, and operatingenvironment contaminants. The HSD44 can withstandthe harshest outdoor environments and the toughestindustrial applications.The 1024 pulses-per-revolutio
n (PPR) are provided by arugged, stainless steel disk, which is read from aspecially designed optical sensor. An enormous 0.025"sensor gap reduces sensitivity to shock, vibration, andmotor bearing wear. The counter-spiral shaft-couplerprovide
s a flexible mount that eliminates resonancethroughout the operating range and will not fatigueunder vibration. Electronics are condensed down to asingle ASIC, reducing the likelihood of electroniccomponent failure.
