CJK-3Z-KB-T Temperature resistant Magnetic Switch (Two Contact Open Closed Type) CJK-3Z-KB-T Temperature resistant Magnetic Switch (Two Contact Open Closed Type) is used to detect the permanent magnet fixed on the tested object and sense the proximity of the position. When the tested permanent magnet or object approaches the required opening distance (adjustable), the output switch signal or indicator light will light up. Due to the use of non-contact detection, it has speed, longevity, and reliability; The characteristic of stable operation in humid and corrosive environments or in flammable (explosive) environments Naming method for CJK series magnetic proximity switches; CJK&mash; Magnetic proximity switch& nbsp;     1~5&mash; Model

The working characteristics of the magnetic proximity switch: it is a non-contact switch that relies 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, and steel equipment. This product complies with Q/ZN.001-2006. Product Description: A 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 the needs of control. The switch contacts are divided into three forms: normally open contact, normally closed contact, and transfer control contact, which are also selected according to actual needs. The magnet and 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 direct current 24V power supply, and the two leads of the switch contacts should be connected in series to the power supply and load, and should not only be connected to the power supply, causing short circuiting and burning of the contacts. The wiring should be as short as possible and as far away from the wiring as possible. 2. Functional non memory magnetic proximity switches should be non-contact and have on/off or switching functions to achieve alignment, limiting, and various control purposes.

The strong magnetic voltage of the electromagnet is designed as C24V pressure magnetic, 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, thermal 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 switching distance. The outer covers of the magnet and contact are made of brass and cast aluminum materials respectively, which are anti vibration, heat-insulating, and epoxy sealed to meet the working requirements in harsh environments with high temperature and dust. The switch working distance can be easily adjusted by tightening the nuts. Main specifications/functions of permanent magnet control magnetic steel ky35P The outer shell of this magnetic steel is made of brass or stainless steel and used in conjunction with limit switches By using the principle of magnetic induction, the internal switch is activated to achieve the purpose of making and breaking contacts, and to control the external circuit. This overcomes the characteristics of poor contact and easy damage of mechanical collision switches. The distance between the switch and the magnetic steel is: less than or equal to 90MM. The large relative movement speed between the switch and the magnetic steel is 15M/S. The reaction of the magnetic switch to the magnet: When the magnetic switch is used in combination with the magnet, the large distance between the magnet and the magnetic switch is 245mm~255mm. The influence of geomagnetism on magnetic switches: Magnetic switches have good capabilities. When a magnet approaches a magnetic switch from far to near, the distance between the magnet and the magnetic switch is represented by L when L> At 255mm, the magnetic switch does not operate, and at 100mm< l<255mm， The magnetic switch is in the active state when l< 100mm magnetic switch in non operating state; This can control the installation position on site and improve the positioning of the magnetic switch. So when installing a magnetic switch, the distance between the magnet and the magnetic switch should be appropriate. Widely used in coal mine elevators.
