Germany IFM proximity switch operating principle IFM proximity switch operating principle 3. Proximity switch classification and structure proximity switch function is when an object is close to the proximity switch and reaches a certain distance, it can announce the signal. It does not require external force to be applied and is a contactless master appliance. It is far more useful than the travel switch, with stroke control and limit maintenance. Proximity switches can be used for high-speed counting, metal body detection, speed measurement, liquid level control, part size detection, and as a contactless button. At present, the proximity switch is widely used and can be divided into the following types according to the operating principle:
High-frequency vibration type: detect various metal body capacitance type: detect various conductive or non-conductive liquid or solid photoelectric type: detect opaque substances Ultrasonic type: detect non-ultrasonic materials electromagnetic induction type: detect magnetic or non-magnetic metals can be divided into garden column type, square type, ditch type, perforation (through) type and separation type according to their appearance and shape. The garden column type is more convenient than the square type device, but its detection characteristics are the same, the groove type detection part is the inside of the tank, used to detect the objects in the tank, the through-type is rarely produced in China, and Japan is more widely used, can be used for small screws or balls and other small parts and buoys assembled into water level detection equipment. The proximity switch can be divided into according to the power supply mode; DC type and communication type, according to the output type, can be divided into DC two-wire system, DC three-wire system, DC four-wire system, communication two-wire system and communication three-wire system.
