Baader Planetarium Homing Sensor Metal Magnet Ring for Steeldrive II Motor Focuser

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. The Metal Magnet Ring is attached between the eyepiece clamp and the eyepiece extension. To install the magnet ring, at first you need to remove the 2" eyepiece holder or the thread adapter for e.g. T-2, M48 or M68. It must be installed parallel to the Steeldrive II.
