FG400P2: Maximum-Range Limit Switch (1:400 Gear Ratio)
Introduction: Model FG400P2
The Model FG400P2 is a 2-contact rotary limit switch featuring the **highest available gear ratio of 1:400**. This makes it the ultimate solution for machinery with extreme travel distances or a very high number of rotations, where standard limit switches cannot provide adequate range.
Working Principle of FG400P2
The core of the FG400P2 is its worm drive mechanism, distinguished by the exceptional **1:400 gear ratio**. This means the internal cams complete one rotation for every 400 rotations of the input shaft. This high ratio allows the switch to accurately track and control machinery movement over vast distances.
The two adjustable cams are used to set the final stopping points at the beginning and end of this extensive travel range, providing a critical safety function for large-scale equipment.
Applications for FG400P2 (1:400 Ratio)
This maximum-range model is essential for the largest and longest-running machinery:
-
Very High-Rise Construction Hoists: For skyscrapers or deep mine shafts with extremely long hoisting cables.
-
Overland Conveyor Systems: For conveyors that span several kilometers in mining or logistics.
-
Large Dam Gates and Waterways: Where the gate travel is extensive and requires many rotations of the drive motor.
-
Telescopic Cranes with Very Long Booms: To accurately measure full extension and retraction limits.
