CJK-3Z-KB/T temperature resistant magnetic switch (two contact open/close type) is used to detect permanent magnets fixed on the tested object and sense the proximity of their positions. When the tested permanent magnet or object approaches the required opening distance (adjustable), the output switch signal or indicator light will turn on. Due to the use of non-contact detection, it has speed, long life, and reliability; The characteristic of stable operation in humid and corrosive environments, or in flammable (explosive) environments CJK series magnetic proximity switch naming method

Reliability: As long as there is no strong magnetic field near the switch and it is installed according to the product technical specifications, it can ensure that the switch operates without misoperation 500000 times, with a reliability of 100%. 6. The working characteristics of magnetic proximity switches are non-contact switches that rely on magnetic induction to fundamentally solve the problem of misoperation caused by contact. 7. Wide application range: mainly used in coke oven equipment, dump truck equipment, steel equipment. This product follows Q/ZN.001-2006. Product Description: The magnetic proximity switch is composed of two parts: a magnet and a switch contact. Magnets are divided into two types: electromagnets and permanent magnets, and can be selected according to control needs. The switch contacts are divided into three forms: normally open contacts, normally closed contacts, and rotary control contacts, which are also selected according to actual needs. The magnet and the contact should be installed on the same axis, and the distance between the two should be within the working distance. There should be no strong magnetic field around the switch contacts to avoid any impact. Electromagnets require a 24V DC power supply, and the two leads of the switch contacts should be connected in series with the power supply and load. It is not allowed to short-circuit and burn out the contacts by only connecting to the power supply. Wiring should be as short as possible and kept as far away from the wiring. 2. Non memory magnetic proximity switches should be non-contact and have on/off or switching functions to achieve alignment, limit and various control purposes.

The strong magnetic voltage of the electromagnet is designed as C24V pressure magnet, which is reliable. The contacts of the magnetic proximity switch and the outer cover of the electromagnet are made of brass and cast aluminum, respectively. It adopts anti vibration, insulation and sealing measures internally to meet the needs of users in harsh environments; The CJK-C magnet is designed as a permanent magnet with different magnetic field strengths, making it convenient for users to choose the switch distance. The outer covers of the magnet and the contact are made of brass and cast aluminum materials, respectively. They are equipped with anti vibration, insulation, and epoxy sealing to meet the working requirements in harsh environments with high temperature and dust. The switch working distance can be easily adjusted by tightening the nut. The main specifications/functions of the permanent magnet control magnet ky35P are that the outer shell of the magnet is made of brass or stainless steel. It is used in conjunction with limit switches By using the principle of magnetic induction, the internal switch is activated to achieve the purpose of connecting and disconnecting contacts, and to control the external circuit, overcoming the characteristics of poor contact and easy damage of mechanical collision switches. The distance between the switch and the magnet is: less than or equal to: 90mm. The large relative motion speed between the switch and the magnet is 15M/S. The response of the magnet switch to the magnet is that when the magnet switch is used in conjunction with the magnet, the large distance between the magnet and the switch is between 245mm and 255mm. The influence of geomagnetic field on magnetic switches: Magnetic switches have excellent ability. When a magnet is used to approach the magnetic switch from far to near, the distance between the magnet and the magnetic switch is represented by L when L>; When 255mm, the magnetic switch does not operate, and when 100mm<; l<255mm， The magnetic switch is in the active state when l<; The 100mm magnetic switch is in a non operating state; This can control the installation position on site and improve the positioning accuracy of the magnetic switch. So the distance between the magnet and the magnetic switch should be appropriate when installing the magnetic switch. Widely used in coal mine hoists.
