This monolithic integrated circuit (from STMicroelectronics) is designed for metallic object detection by sensing variations in high frequency Eddy current losses. The capacitive, inductive, and magnetic proximity sensors are used in specific electronic applications. The actual electrical circuit of an inductive sensor is rather complicated, often involving ASICs (Application-Specific Integrated Circuits), and the circuits are typically the proprietary intellectual property of the manufacturer. The sensor mounting accessories you choose will depend on the type of sensor you're using. The digital Hall sensor can only detect if a magnet is present or not (0 or 1) but an analog hall sensor’s output varies based on the magnetic field around the magnet that is it can detect how strong or how far the magnet is. A monostable multivibrator based on NE555 (IC1) and a toggle flip flop based on CD4013 (IC2) does the rest of the circuit. The GRI-4402-A offers SPDT form C contacts so they can be used in open or closed loop circuits. This IC can detect magnetic fields. Are you a Circuit Maker?
