  The magnetic proximity switch CJK-4Z-KB/T is a domestically produced product. Due to the use of magnetic induction principle, it fundamentally solves the impact caused by any electric field interference. This series of switches has a long operating distance, strong performance, good sealing performance, stable and reliable magnetic force, hemispherical working characteristics, easy installation, long service life, and can work in high temperatures, temperatures, and harsh environments. They are widely used as position control switches in steel rolling, coking, shipbuilding, mining, lifting, transportation, and other fields, or to replace the original slide contactor mechanical limit switches. They are domestically produced products and components that achieve contactless transmission of control signals. Magnetic proximity switch CJK-4Z-KB/T technical parameters 1, technical indicators; (1) Output signal of proximity switch: When the contact is conducting, the voltage drop should not exceed 0.5V (with a current of 1A injected); When the contact is disconnected, the output resistance should not be less than 100KΩ (Applying a voltage of 12V DC as an example); (2) Contact form: normally open, normally closed, normally open+normally closed; (3) Action point distance: not less than 120mm; (120-150) (4) Magnetic steel size: 290mm× 77mm× 48mm； (5) Magnetic induction strength of magnetic steel: 1900GS~3500GS; (6) Contact capacity: 12V, 24V, 36V, 110V, 127V, 220V/1A& nbsp; Structural characteristics and working principle of (resistive load) mining proximity switch, internally using a reed tube and a piece of magnetic steel, with melting point and wear-resistant characteristics. Sealing the reed tube and magnetic steel inside the shell can prevent impact and has strong capabilities. The magnetism of the small magnetic steel is insufficient to attract the springs inside the reed tube, and the switch remains in a normally open state. When the magnetic steel approaches the switch from far to near in one direction, the spring contact inside the reed tube is attracted. When the magnetic steel leaves, the state of the reed tube is maintained because the magnetic steel inside the switch is magnetized at the same time. When the magnetic steel approaches the switch again from the opposite direction, it is magnetized in the opposite direction, causing the magnetism to decrease, causing the reed spring to spring open due to elasticity, and the contact point to also disconnect.
