Metal Magnet Ring for Homing-Sensor of Steeldrive II - fitting for Baader Diamond Steeltrack focusers. The Steeldrive II motor unit features a contactless (wearfree) homing sensor (hall-effect sensor). It is activated by a magnet attached to the moving part of the focuser. It enables precise homing and repeatable approach of saved absolute positions as well as reference of the mechanical endstop.
