The deviation switch ROS-2D 380V 2A bidirectional deviation switch ROS-2D 380V 2A bidirectional Ramsey deviation switch ROS-2D and anti deviation switch are fixed at the top or bottom of the conveyor longitudinal beam, usually installed at a distance of 0.3 to 2 meters from the head or tail drum at both ends of the belt. After the belt deviates, it forces the action arm to deviate and triggers the alarm microswitch. If it continues to deviate to the stop contact and triggers another set of contacts, the conveyor will stop protectively· The universal installation design allows the anti deviation switch to be installed freely on the top or bottom of the conveyor longitudinal beam. The sturdy cast aluminum shell has a protection standard of NEMA4, and special environments can choose special surface treatment. The integral cover plate is easy to connect and adjust. The cover plate can be removed without removing the action rod. The rated speed of the action rod bearing is 5000 revolutions per minute, and the applicable belt speed can reach 6.35 meters per second. The normal angle adjustment range of the action rod is 22.5 °. The alarm contact acts when the normal angle is 10 degrees, and the stop contact acts when the normal angle is 20 degrees< Technical specifications: Rated value of switch contacts: 2 SPDTs, 10A/500V, for alarm and shutdown use. Housing: cast aluminum weather proof shell, protection level NEMA 4. Normal alarm angle: adjustable within 22.5 ° deviation from vertical direction. Force: 5 pounds. Wire opening: 3/4 "-14NPT. 1. The deviation switch is set on both sides of the conveyor belt, and the vertical rollers should be perpendicular to the edge plane of the conveyor belt, and the two sides of the conveyor belt should be at 1/3 of the height of the vertical rollers.
