KHC100 mining intrinsic safety explosion-proof magnetic proximity switch, mining intrinsic safety magnetic proximity switch (hereinafter referred to as proximity switch) can be used in coal mines with methane and coal dust hazards. This proximity switch is used in conjunction with the KHT138-Z host. KHC100 Mining Intrinsic Safety Explosion proof Magnetic Proximity Switch Product Structure 1. Mining Proximity Switch Composition: composed of proximity switch magnetic head and magnetic steel. 2. Proximity switch size (Figure 1): 20mm× 83mm. KHC100， Technical parameters of intrinsically safe magnetic proximity switch (1) Contact capacity of proximity switch: 24V/1A (resistive load); The contact resistance should be less than 1; When the contact is disconnected, the output resistance should be greater than 100k; (2) Contact form: normally open; (3) Action point distance: not less than 100mm; (4) Reset point distance: not greater than 190mm; KHC100， Intrinsically safe magnetic proximity switch; Working principle: (1) The magnetic steel gradually approaches the proximity switch, and when it reaches the action point position, the contact point should be conductive; Continue to approach while keeping the contact state unchanged; The magnetic steel gradually moves away from the proximity switch, and when it reaches the reset point position, the contact should be disconnected; Continue to move away, keeping the contact state unchanged< (2) The distance between the magnetic steel and the proximity switch should be maintained at 100mm. When the magnetic steel passes through the proximity switch at a speed not exceeding 10m/s, the proximity switch should be able to work normally; Mining magnetic switch, magnetic proximity switch KHC100KMW120GKSC1010GKSC1010G-1/220KG1010G-1-12 KG1010G-2-12、KG1010G-3-12、KG1010G-4-12、KG1010G-1-22、KG1010G-2-22、KG1010G-3-22、KG1010G-4-22、KG1010G-5-22KG1010G-1-13、KG1010G-2-13、KG1010G-3-13、KG1010G-4-13、KG1010G-1-23、KG1010G-2-23、KG1010G-3-23、KG1010G-4-23、KG1010G-5-23 KSC1010G-1-12、KSC1010G-2-12、KSC1010G-3-12、KSC1010G-4-12、KSC1010G-1-22、KSC1010G-2-22、KSC1010G-3-22、KSC1010G-4-22、KSC1010G-5-22KSC1010G-1-13、KSC1010G-2-13、KSC1010G-3-13、KSC1010G-4-13、KSC1010G-1-23、KSC1010G-2-23、KSC1010G-3-23、KSC1010G-4-23、KSC1010G-5-23
