Ready for Sale Mining Magnetic Proximity Switch Strong Anti-Interference Ability Mining Intrinsically Safe Magnetic Proximity Switch

Product Description:
The magnetic proximity switch is composed of two parts: magnet and switch contact. Magnets are divided into two types: electromagnets and permanent magnets, which are selected according to the needs of control. Switch contacts are divided into three types: normally open contacts, normally closed contacts and transfer 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 contact to avoid any impact. The electromagnet needs to be powered by 24V DC. The two leads of the switch contact should be connected in series with the power supply and the load, and the power supply should not be connected alone to cause a short circuit and burn the contacts. The wiring should be as short as possible and as far away from other wiring as possible.
2. Function: Non-memory magnetic proximity switch is non-contact and has on, off or conversion functions to achieve positioning, limit and various control purposes.
Overview
The mining proximity switch is an intrinsically safe structure with internal sealing. The switch adopts the principle of magnetic induction, has no collision and strong anti-interference ability. It is widely used in coal mines, chemical industry, petroleum and other dangerous places. It is an ideal sensor in modern automatic control systems.
Mining proximity switches are mainly used for position detection of moving objects. This switch is a memory type proximity switch. When the magnet passes through the mining proximity switch from one direction, the output contacts are closed and maintained. When the magnet passes through the proximity switch again from the other direction, the output contacts are opened and maintained.
The mining magnetic proximity switch is a new type of switch developed in automation. It is used in conjunction with intrinsically safe electrical equipment. It is an ideal sensor for the mechanical body of the wellhead door, loading and unloading gate, rocking platform, and cart machine linkage locking. The outer shell is made of brass casting and machined, and has the characteristics of anti-smashing, high strength, dustproof, and waterproof. The inner core adopts epoxy resin glue sealing structure, which eliminates the dangerous factors of arc and improves safety and reliability. The control magnet is made of stainless steel, and the pouring technology is used to fix the magnetic magnet in the shell. It has stable performance and can be directly installed on iron materials without causing short circuit of the magnetic field.
