FG12.5P4: 4-Contact Limit Switch with 1:12.5 Gear Ratio
Introduction: Model FG12.5P4
The Model FG12.5P4 is a specialized version of the 4-contact rotary limit switch, featuring a 1:12.5 gear ratio. This lower gear ratio makes it exceptionally suited for applications where the input shaft undergoes fewer rotations to complete its full range of motion. It provides highly precise and responsive control over shorter distances of travel.
Working Principle of FG12.5P4
The FG12.5P4 utilizes a worm drive mechanism to transfer rotation to its four internal cams. The 1:12.5 gear ratio means that for every 12.5 rotations of the input shaft, the cams complete one full rotation. This allows for very fine and accurate adjustment of the four switching points within a relatively small operational range.
This precision is ideal for setting multiple actions, like slowdown, stop, and alarm signals, in applications where the total travel distance is limited but high accuracy is paramount.
Applications for FG12.5P4 (1:12.5 Ratio)
This model is specifically useful for machinery requiring precise control over a limited range:
-
Short-travel Hoists: For workshop hoists or specific lifting tasks with low headroom.
-
Machine Tool Positioning: For controlling the position of tool heads or workpieces.
-
Valve Actuators: For precise control over the opening and closing of industrial valves.
-
Automated Guided Vehicles (AGVs): For controlling specific mechanical actions like lifting forks.
