What is a Proximity Sensor? Proximity Sensors convert data on the motion or presence of an object into an electrical sign. There are three sorts of detection programs that do that conversion: repo.getmonero.org techniques that use the eddy currents which might be generated in metallic sensing objects by electromagnetic induction, programs that detect changes in electrical capability when approaching the sensing object, and methods that use magnets and reed switches. The Japanese Industrial Requirements (JIS) define Proximity Sensors in JIS C 8201-5-2 (Low-voltage switchgear and controlgear, Half 5: Management circuit units and switching elements, Section 2: Proximity switches), which conforms to the IEC 60947-5-2 definition of non-contact place detection switches. This Technical Rationalization defines all inductive sensors which are used for detecting metallic objects, capacitive sensors which can be used for detecting metallic or non-metallic objects, and sensors that utilize magnetic DC fields as Proximity Sensors.
