The Aleph line of proximity sensors includes both reed switch and solid-state magnetic proximity sensors. Both types feature models that are actuated by a magnet or magnetic shield and offer high reliability and long operational life. Proximity sensors are used extensively in industry in such diverse applications as: . Washing machines and driers . Paper transport sensing in business machines . Paper tray detection in copiers o Auto-stop in audio equipment . Vibration detection . Open-door and closed-door detection o Detection of burnt-out filaments in lamps . Stroke position detection in hydraulic equipment o Transport (conveyor belt) detection . Key switch detection in home appliances MATERIAL: Barium-Ferrite MAGNETIC FLUX DENSITY: 450 ~ 750 Gauss MAGNETIZATION: Fully magnetized
