KGE-27 intrinsically safe magnetic sensor for mining. KGE-27 magnetic induction sensor is an important sensor that provides deceleration points for mine hoists. It is a new type of travel switch used 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. The working principle and characteristics of position switches KGE-27 and KGE-27 magnetic induction sensors. The permanent magnet limit switch consists 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 switch 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. Structure: Type 1 and Type 2 of this switch are general mining structures, while Type 2A is an explosion-proof structure with an IP54 outer shell 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)<
