FG400P4: Ultimate Limit Switch for Extreme Range & Multi-Stage Control
Introduction: Model FG400P4
The FG400P4 combines the highest gear ratio of 1:400 with 4 independent contacts for precise multi-stage control, making it perfect for large-scale industrial machinery and critical automation systems.

Advanced Working Principle
FG400P4 uses a worm drive with a 1:400 gear ratio to track extensive rotations. Four independent cams enable sequential multi-stage control over vast distances.
Example in dam gates or large machinery:
- Initiate slow opening
- Transition to fast opening
- Slow down before full open position
- Activate final stop and status signal
Critical for applications requiring massive scale and precise control.
Applications
-
Large Dam Gates & Sluiceways: Precise multi-stage control for massive gates.
-
Overland Conveyor Systems: Complex sorting or stopping along kilometer-scale conveyors.
-
High-Rise Elevators & Hoists: Extreme travel and multi-speed control.
-
Telescopic & Observatory Domes: Sequential control over wide motion range.
