Explosion proof magnetic proximity switch supplier

KHC100 intrinsically safe explosion-proof magnetic proximity switch for mining useThe mining proximity switch is an intrinsically safe magnetic proximity switch (hereinafter referred to as the proximity switch) that can be used in coal mines with methane and coal dust hazards. This proximity switch is used in conjunction with the KHT138-Z host.

product structure

1. Composition of mining proximity switch: composed of proximity switch magnetic head and magnetic steel.

2. Approaching switch size (Figure 1): 20mm x 83mm.

KHC100， Technical parameters of intrinsic safety 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， Intrinsic safety magnetic proximity switch

Working Principle:

(1) The magnetic steel gradually approaches the proximity switch, and when it reaches the action point position, the contact should be conductive; Continue to approach, the contact status remains 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 stay away, keeping the contact status unchanged;
(2) The distance between the magnet and the proximity switch should be maintained at 100mm. When the magnet passes through the proximity switch at a speed of no more than 10m/s, the proximity switch should be able to work normally;
