The intrinsically safe explosion-proof magnetic proximity switch CJK-2C and CJK-2Z for mining are 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& HANGRONG/Zhuoxin stock, 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 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. CKJ series function introduction: Configure the number of contacts and magnets for magnetic proximity switches based on the on-site detection and control points of each user.
