Two stage deviation switch ROS-2D HFKPT1-N conveyor accessories ROS-2D HFKPT1-N conveyor accessories ROS-2D anti deviation switch can be fixed at the top or bottom of the conveyor longitudinal beam, and the action arm is about 25 to 75mm away from the edge of the belt. Usually installed on both sides of the belt at a distance of 0.3 to 2 meters from the head or tail drum. 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 in a sturdy cast aluminum shell, with a protection standard of NEMA4. In special environments, special surface treatment is optional, and 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, suitable for belt speeds less than 6.35 meters per second. The normal angle adjustment range of the action rod is 22.5 °, and the alarm contact action is triggered when the normal angle is 10 °. The shutdown contact action is triggered when the normal angle is 20 °. Application scope: conventional belt conveyors, ship loading and unloading systems, underground and cableway supported belt conveyors, stacking/reclaiming conveyors, inclined and shuttle conveyors, crane/excavator boom limit skirt feeders/conveyors, heavy-duty limit switches. Technical specifications: Model: ROS-2D, HFKPT1-N open contact rated value: two SPDT passive contacts, 10A/500V, cast aluminum windproof housing for alarm and shutdown, protection level NEMA4, normal alarm angle: adjustable force within 22.5 ° deviation from vertical direction: 5 pounds, wire opening: 3/4 "-14NPT
