Tear switch
Tear switches are installed in pairs on both sides of the conveyor belt, connected by two segments of aviation steel wire ropes wrapped in ethylene. One end of the rope is always fixed on the support bracket, and the other end is connected to the pull ring of the tear switch. A closed circuit is formed by two sections of wire rope in the lower part of the belt. When an object or torn belt is suspended and one or two wires are swept down, a fault is detected. Due to the force acting on the wire rope, it pulls out the pull ring shaft outward but causes the self locking handle to bounce upwards. At this time, the two micro switches inside the machine issue a warning or turn off the conveyor. After troubleshooting, press down on the self selling handle to reset the camshaft inside the machine and wait for the machine to start.

- Tear switches are widely used in various fields such as metallurgy, coal, cement building materials, mining, power, ports, metallurgy, chemical engineering, etc., including conventional belt conveyors, underground cable support belt conveyors, ship loading and unloading systems, stacker/reclaimer conveyors, inclined and shuttle conveyors, cranes, excavators, boom limiters, skirt feeders, and other types of conveyors.
Description
The tear switch is mainly used when the conveyor belt is torn, punctured, damaged at the junction, or sharp objects protrude. The tear switch can provide warning signals to the monitoring personnel or shut down the conveyor< Br/>
Structural characteristics
The result is simple, sturdy, and does not require frequent maintenance< Br/>
Cast aluminum shell with anti-corrosion coating
Overloaded microswitch contacts
High sensitivity, with a force of only 0.9Kg to trigger the switch
Equipped with self-locking function, convenient for maintenance< Br/>
Contact capacity: 10A/125250V or 480V (AC)< Br/>
Protection level: IP67 shell dustproof, anti-corrosion, rainproof, suitable for outdoor installation< Br/>
Number of switches: 2 normally open and 2 normally closed (can be increased)
The switch can be connected in a normally open or normally closed form according to user needs< Br/>
Environmental temperature: -20--60 ℃
