Run off switch HLBHP-MC2JDC2238& LLD2-3 Belt Switch, also known as Anti Bias Switch. It is a product used to detect the deviation of the conveyor belt of a belt conveyor. It is a safety protection device that automatically alarms and stops the conveyor belt in the event of deviation. The deviation switch plays a protective role in the belt conveyor site, therefore it must meet the IP protection level< The HLBHP-MC2JDC2238 switch is divided into two positions to detect the degree of deviation and twisting of the conveyor belt. Based on the degree of deviation and twisting of the belt, automatic alarm and shutdown are achieved to avoid accidents such as expensive conveyor belt damage and material scattering caused by belt twisting. This switch is easy to install, reliable to operate, and is one of the protective devices for belt conveyors. During the operation of the conveyor, when the belt deviates and comes into contact with the switch vertical roller, the vertical roller rotates automatically. If the deviation continues to increase, the squeezing vertical roller will shift. The first level switch signal is used for alarm. If this signal is connected to the running adjustment device, it can achieve automatic adjustment of running deviation without stopping the machine. The second level switch signal is used for shutdown. Connect this signal to the control circuit to achieve automatic shutdown under severe deviation. After troubleshooting, when the tape leaves the vertical roller for normal operation, the vertical roller can automatically reset. Technical indicators 1. Rated voltage: AC380V2.
