Mining sealed magnetic proximity switch; Model: H5QKG10101, Overview< Our company's H5QKG1010 series mining sealed magnetic proximity switches are designed and manufactured in accordance with the actual needs of China's mine hoist electrical control system, taking into account similar switch points< The H5QKG1010 series magnetic proximity switch is a type structure with the symbol& lquo;ExmbI&rquo;， It is IP54. The H5QKG1010 sealed magnetic proximity switch adopts the principle of magnetic induction. Has characteristics such as collision free and strong ability. The KG1010 sealed magnetic proximity switch is mainly used for detecting the position of moving objects. When the magnetic steel on the moving object passes through, the output contact of the proximity switch closes, and when it leaves, the contact opens. H5QKG1010 is widely used in places with sexual hazards such as coal mines, chemicals, and petroleum, and is a sensor in modern automatic control systems< br />2、 Working principle< The H5QKG1010 series adopts the principle of magnetic induction and is amplified by electronic power to achieve on/off control of external circuits. The H5QKG1010 series sealed magnetic proximity switch is used in conjunction with the KY35 series control magnetic steel. The H5QKG1010 sealed magnetic proximity switch is fixedly installed in the position that needs to be controlled, and the magnetic steel is directly installed on the outside of the controlled moving object. When the magnetic steel passes back and forth through the switch, it drives the switch to work. 3. Technical parameters< 1. Technical specifications of H5QKG1010 sealed magnetic proximity switch

a) Rated voltage of proximity switch: AC36V~260V; C36V~260V;
b) Proximity switch contact method: normally open< Br/>c) Relative speed between proximity switch and magnetic steel: 15m/s< The action distance between the switch and the magnetic steel depends on the size of the magnetic steel, and the action distance is 150mm.

2. Environmental conditions and precautions for the use of H5QKG1010 magnetic proximity switch
