Mining Intrinsic Safety Explosion proof Magnetic Proximity Switch CJK-5Z-KB/T2 Product Description Usage; Used to detect the permanent magnet fixed on the tested object and perceive the proximity of its 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. The main characteristics of CJK-5Z-KB/T2 mining intrinsically safe explosion-proof magnetic proximity switch products are: 1. Long operating distance: a. Electromagnet * large operating distance 120mm; b. Permanent magnet with a large operating distance of 150mm. 2. Strong load carrying capacity: CJK-1Z/T can directly carry 3A (value) load, with intermediate relay transition Reliable and convenient. 3. Sensitivity, reaction speed: Response time less than 2.5ms. 4. Can work in extremely harsh environments: a. Adaptable to a wide temperature range: -50 ℃& mash;&mash;+120℃  b. Strong:. c. Waterproof and dustproof. 5. Reliable: As long as there is no strong magnetic field near the switch and it is installed according to the product technical manual requirements, it can ensure that there is no misoperation of the switch 500000 times, with a reliability of 100. 6. 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. Product Description: 1. 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 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. Description of alignment and control configuration: Based on the detection and control points of each user on site, configure the number of contacts and magnets for the magnetic proximity switch. Installation requirements: It can be installed indoors and outdoors, and is suitable for an ambient temperature of -55 ℃~ 125℃  Contact 1. Large action distance: 120mm2 On/off difference: within 30mm Response time: less than 10ms4 Vibration frequency: 20G 10-1000HZ5 Excitation voltage: C24V; Plun; 2V6. Excitation current: 0.6A7 Environmental humidity: -55 ℃; mash;+125℃8. Contact capacity: 80VA9 Large switching current: 0.8A10 Voltage of large switch: C350V AC300V11 Contact resistance: less than 0.1Ω 12. Weight: 3.6kg magnet, 0.6kg contact, 13 Using JZ7-44 as the load, with a lifespan of 500000 times, the 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. Magnetic proximity switch CJK-5ZB Magnetic proximity switch CJK-5ZKB Magnetic proximity switch CJK-5Z-K/T
