FG400P2: Maximum-Range Limit Switch (1:400 Gear Ratio)
Introduction: Model FG400P2
The FG400P2 is a 2-contact rotary limit switch featuring the highest available gear ratio of 1:400. Ideal for machinery requiring extreme travel distances or high numbers of rotations, this switch ensures reliable end-limit control where standard switches fall short.

Working Principle of FG400P2
The FG400P2 uses a worm drive mechanism with an exceptional 1:400 gear ratio. Each internal cam rotation corresponds to 400 input shaft rotations, allowing precise tracking of long-travel machinery. Two adjustable cams set the final stopping points, ensuring maximum safety and operational reliability.
Applications
Suitable for large-scale and long-travel machinery:
-
Very High-Rise Construction Hoists: For skyscrapers and deep mine shafts.
-
Overland Conveyor Systems: Conveyors spanning kilometers in mining or logistics.
-
Large Dam Gates and Waterways: Extensive gate travel control.
-
Telescopic Cranes with Very Long Booms: Accurate extension/retraction limits.
