Jiangsu Suzhou HY1-U contactless magnetic switch with LED indicator light working principle: The cylinder magnetic switch is installed on the outer side of the cylinder barrel. A cylinder can accommodate various types of cylinders, but the cylinder barrel is made of materials with weak magnetic conductivity and strong magnetic isolation, such as hard aluminum, stainless steel, brass, etc. Install a YONG magnet (rubber magnet) magnetic ring on a non-magnetic piston. When the magnetic ring moves close to the switch with the piston, the two springs of the tongue spring switch, PIAN, are magnetized and attracted to each other, and the contacts close; When the magnetic ring moves away from the switch, the spring PIAN loses excitation and the contact opens. When the output point is closed or disconnected, a signal is issued (or the signal disappears) to control the corresponding solenoid valve to complete the switching action. Magnetic switches generally have indicator lights for switch action and overvoltage protection circuits inside, which are encapsulated in a resin shell. The magnetic switch function of the cylinder: 1. The magnetic switch of the cylinder is mainly used as a position signal to detect the presence or absence of the magnetic switch signal, and to achieve position control, stop in place, and start in place for the cylinder< br />2、 The signal of the magnetic switch can be directly output to TPC; The input end of the 8-8T table program can achieve the above functions, and indirectly achieve in place, not in place, material detection through judgment. It can also count the number of cylinder actions and control the number of cycles< br />3、 If magnetic switches are not used, various actions can also be controlled through internal timing control. Due to the error in the stroke time of the unstable air pressure cylinder, setting a longer timing time is necessary for reliable operation. This timing control will reduce the efficiency of the equipment. Using magnetic switches to detect the position and status of cylinders can improve the efficiency of the controlled equipment.
