LE1 Series Magnetic Starter

LE1 Series Magnetic Starter is a kind of electronic device based on the magnetic field principle, which realizes the on-off control of the air compressor circuit through the combination of magnetic sensing element and trigger device. When an external magnetic field is close by, the magnetic sensing element will be affected, thus triggering the switch action to close or break the circuit, and then control the start and stop of the air compressor.

Principle of operation

The working principle of LE1 Series Magnetic Starter mainly relies on the effect of magnetic field on magnetic material. Specifically, when an external magnetic field acts on a magnetic sensing element (such as a reed switch), it will cause the magnetic metal sheet inside it to undergo a magnetic change, thus closing or breaking the contacts and realizing the on-off of the circuit. This process is fast and reliable, ensuring that the air compressor starts promptly when needed and stops safely when the task is completed.

Application Scenario

Air compressor magnetic start switches are widely used in various applications where air compressors are required, such as manufacturing, construction, and automotive repair. In these fields, air compressors are usually used to provide compressed air to drive various pneumatic tools and equipment. The introduction of magnetic start switch not only improves the control accuracy and reliability of air compressor, but also reduces the operation difficulty and maintenance cost.

Advantages and Features

High reliability: Magnetic start switch is made of magnetic material, which has stable performance and long service life.

Fast response: Due to the rapid action of the magnetic field, the magnetic start switch is able to complete the on-off action of the circuit in a very short time.

Easy to control: Magnetic actuator switches are usually connected to a control system and can be precisely controlled by remote control or automatic control system.

Safety performance: Magnetic actuator switches have overload, short circuit and other protection functions, can cut off the circuit in time under abnormal conditions, to ensure the safety of equipment and personnel.
