Application of reed switch in industry

Reed switch sensor, in cooperation with programmable logic controller (PLC) and microcontroller with a wide working voltage range, has a high running speed. When weak magnets are used, the dry spring sensor can also detect any ferrous metal parts.Safety-oriented application of reed switch Optical fiber sensor lenses need extra clean guidance for sensing applications. A reed switch and a magnet are combined into an assembly with a specific distance, and a (NC) normally closed reed switch sensor is formed between them. When the permanent magnet part comes to the middle of them, the magnetic field starts to split and the reed switch opens. (NO) The normally open reed switch sensor can be designed with a normally closed reed switch on one side and a magnet on the other side, which is enough to ensure that the normally closed reed switch switch is open. The sensor base on magnetic spring switch can work in a very dirty industrial environment, and grease and dust do not affect its work. Common applications include conveyor belt part sensing and industrial mixer speed sensing.Sensing at the end position of cylinder and piston Most air cylinders, pistons, linear sliding and rotating actuators and built-in magnets generate end position sensing. Reed switch sensor is used to sense the position and middle position of the terminal and the signal can be processed to further indicate the application of PLC. The very high detection speed of reed switch sensor and the high scanning speed PLC program work together. The dry spring sensor can also be equipped with an indicator light (light emitting diode) to help locate the angle of the piston and cylinder which is easy to adjust or rotate the actuator.
