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 . Auto-stop in audio equipment . Vibration detection . Open-door and closed-door detection . Detection of burnt-out filaments in lamps . Stroke position detection in hydraulic equipment . Transport (conveyor belt) detection . Key switch detection in home appliances Contact Form NO Contact Rating 50W max. Switching Voltage 200VDC max. Switching Current 1.0A max. Breakdown Voltage (open contact) 250VDC min. Contact Resistance (initial) 0.3W max. Electrical Life (resistive loads) 106 (6VDC, 10mA) Operating Temp. -10 ~ +60°C
