ROS-2D防偏开关：
ROS-2D防偏开关可固定在输送机纵梁的顶部或底部，动作臂距皮带边缘大约25到75mm。通常安装在皮带两侧距头部或尾部滚筒0.3到2米的地方。皮带跑偏后，迫使动作臂偏离，触动报警微动开关。如果继续偏离到停机触点，触动另一组触点，输送机就会保护性停机。
通用的安装设计可使防偏开关随意安装在输送机纵梁顶部或底部

ROS-2D anti-bias switch can be fixed to the top or bottom of the longitudinal beam of the conveyor, and the action arm is about 25 to 75 mm. from the edge of the belt usually installed on both sides of the belt 0.3 to 2 meters from the head or tail drum. After the belt runs off, force the action arm to deviate, touch the alarm fretting switch. if continue to deviate to the stop contact and touch another set of contacts, the conveyor will protect the stop. The general installation design allows the anti-bias switch to be installed at the top or bottom of the longitudinal beam of the conveyor sturdy cast aluminum housing, protective standard NEMA4, special environment optional special surface treatment The integral cover plate is easy to connect and adjust; the cover plate can be removed without removing the action rod Action rod bearing rated speed 5000 rpm, suitable for belt speed less than 6.35 m/s Action bar normal angle adjustment range of 22.5° ° normal angle is 10 times alarm contact action, stop contact action when normal angle is 20°. Scope of application: Conventional belt conveyor, ship handling system, underground, ropeway support belt conveyor Stacking/feeding conveyors, tilt and shuttle conveyors, crane/digger boom limit Skirt feeder/ Conveyor, heavy duty limit switch Technical specifications: Model: ROS-2D Size: Shell L*W*H (mm): mm.389 from top of movable arm to bottom of shell 191*135*109 Hole size: L*W (mm):171*100. Open contact rating: two SPDT passive contacts ,10 A/500V, for alarm and shutdown Cast aluminum windproof housing, NEMA4 protection grade Angle of normal alarm: adjustable in direction ° deviation from vertical 22.5 Force :5 lbs Conductor opening :3/4"-14 NPT
