Performance Characteristics Of Magnetic Proximity Switches

The magnetic proximity switch is a kind of proximity switch. The magnetic proximity switch is one of many types in the sensor family. It is made by the use of electromagnetic working principle and advanced technology. It is a position sensor. It can transform the non-electricity or electromagnetic quantity into the desired electric signal through the change of the positional relationship between the sensor and the object, so as to achieve the purpose of control or measurement. A larger detection distance can be achieved with a small switch volume. It can detect magnetic objects (usually permanent magnets), and then generate trigger switch signal output. Since the magnetic field can pass many non-magnetic objects, this triggering process does not necessarily require the target object to be directly approached to the sensing surface of the magnetic proximity switch, but to transmit the magnetic field to a long distance through a magnetic conductor (such as iron). For example, the signal can pass The high temperature is transmitted to the magnetic proximity switch to generate the trigger action number.

Among all kinds of switches, there is a component that has the ability to "perceive" objects approaching it-displacement sensor. Use the sensitive characteristic of the displacement sensor to approach the object to achieve the purpose of controlling the switch on or off, this is the proximity switch.

When an object moves to the proximity switch and approaches a certain distance, the displacement sensor will "sense" and the switch will act. Usually this distance is called "detection distance". Different proximity switches have different detection distances.

Sometimes the inspected objects move to the proximity switch one by one at a certain time interval, and then leave one by one, and this is repeated continuously. Different proximity switches have different responsiveness to the detected object. This response characteristic is called "response frequency".
