The Macro Sensors R1380-050 are a series of contactless, fractional-turn, absolute output rotary position sensors that provide an analog voltage or current output proportional to shaft rotation over a total range of 100°. They are ideal sensors for measuring the position of quarter-turn ball and butterfly valves, flue dampers, weir gates, mail sorters, conveyor check weigher systems, dancer arm tensioners, and myriad other applications involving 90° shaft movement.
