For Protection of Belt Conveyors and Personnel

• Universal design for mounting on top of conveyor stringers   
• Rugged cast aluminum enclosure. NEMA4 on standard units   
• FM approved Class II div. 1 units have a two part baked urethane finish for extra protection from salt and high corrosion areas   
• Full cover plate permits complete, easy access to terminal switch and cams   
• Cover plate can be removed without detaching actuating arm   
• Heavy-duty, "micro-switch" contacts   
• Stocked by distributors   
• Heavy duty roller bearings rated to 1250 f.p.m.      
• Normal angle of arm adjustable in 22.5° increments   
• Available with alarm/shutdown sequence

Run-Off Switches are mounted on the top or bottom of the conveyor stringers with the actuating arm adjusted to the outside edges of the belt.

Under normal conditions with the belt trailing properly, the edge of the belt clears the actuating arms by 1" or more (adjustable by switch positioning).

If the belt skews or runs-off contacting actuating arm, displacing it from the arm's normal vertical position, one or more of the microswitches are contacted.
