KGE-27 mining sealed magnetic proximity switch
I. Purpose
Kycx-1- (2) type permanent magnet limit switch is an important sensor for providing deceleration points for mine hoists, and is a new type of excellent travel switch for various equipment travel control and position detection. Suitable for coal mine wellhead and underground areas without gas or coal dust hazards, such as the speed switch of the hoist shaft, parking and over roll protection switch, unloading gate, air door control, automatic control devices such as mine car counting and position switches, and relay protection devices for speed switching circuits. 2、 Working principle and characteristics; KGE-27 Mining Sealed Magnetic Proximity Switch
The permanent magnet limit switch is composed of a static magnetic switch and a moving control magnetic steel. It adopts the principle of magnetic induction and directly attracts the contact of the reed tube to achieve on/off control of the external circuit., Easy to install, sensitive to action, and with a long service life, this product has the general "MA" logo for mining use. Due to the fact that this switch is essentially a non-contact induction magnetic switch with a reed tube as the main body and an additional power supply, it overcomes the characteristics of poor contact, unreliability, and easy damage of commonly used mechanical collision switches. This product has stable performance, reliability, strong vibration resistance, convenient installation, and long service life, and its performance has reached the level of similar products. It is a replacement product for coal mine travel control and a substitute product for imported equipment< III. Structure: Type 1 and Type 2 of this switch are general mining structures, while Type 2A is an explosion-proof structure. The IP54 shell is made of copper alloy casting, which has strong anti impact, waterproof, and seismic performance< This switch is divided into three types: Type 1, Type 2, and Type 2A. Type 1 is composed of an external magnetic steel and a reed switch (a normally open contact). Type 2 and 2A consist of an external magnetic steel and two reed switches (one normally open and one normally closed contact)< 4. Operating Environment and Installation Conditions
