This is a 450 mm heavy-duty electric linear actuator with a built-in potentiometer and a thrust of up to 8000 N, engineered specifically for applications requiring strong thrust and position control.
It has a built-in potentiometer with three output wires connected. When the linear actuator moves, the resistance value between the output lines changes accordingly. In this way, we can obtain the corresponding movement position of the linear actuator by measuring the resistance value.
It is widely used in doors, windows, cellars, trapdoors, hatchways, solar tracking system, medical devices, agricultural machinery, vehicles, ships, elevator platforms, lifting tables, TV lifts, robots, cabinetries, massage sofas, electric beds, medical chairs, and other electrical equipment. It can open, close, push, pull, lift, and descend these devices.
It can also replace hydraulic and pneumatic products to save power consumption.

Operation
The electric linear actuator has a five-core cable.
1. The brown and blue lines are two power lines of the electric linear actuator.
When the brown power wire is connected to the positive pole of the DC power supply and the blue power wire is connected to the negative pole of the DC power supply, the stroke rod will extend outward; after switching the power in the reverse direction, the stroke rod will retract inward.
2. The red, green and yellow wires are the three output wires of the potentiometer.
The yellow and red wires are connected to the two terminals of the potentiometer, it is a fixed resistance value.
When the linear actuator moves, the resistance value between green wire and red wire or green wire and yellow wire changes accordingly. In this way, we can obtain the corresponding movement position of the linear actuator by measuring the resistance value. When the linear actuator is extended outwards, the resistance value between green and yellow wires will decrease accordingly, and the resistance value between green and red wires will increase accordingly. When the linear actuator is retracted inward, the resistance value between green and yellow wires will increase accordingly, and the resistance value between green and red wires will decrease accordingly.
For example, a linear actuator with a stroke of 150mm and a built-in potentiometer of 10K ohms.
When the linear actuator is fully retracted, the resistance value between green wire and red wire is 0.4K ohms, and the resistance value between green wire and yellow wire is 9.6K ohms.
When the linear actuator is extended to the 100mm position, the resistance value between green wire and red wire is 3.3K ohms, and the resistance value between green wire and yellow wire is 6.7K ohms.
When the linear actuator is fully extended, the resistance value between green wire and red wire is 4.8K ohms, and the resistance value between green wire and yellow wire is 5.2K ohms.
Stroke and Length (Model 0041555-2)
| Parameter | Value |
|---|---|
| Stroke | 450mm |
| Retraction Length | 700mm (center distance between two mounting holes when the linear actuator is fully retracted) |
| Extension Length | 1150mm (center distance between two mounting holes when the linear actuator is fully extended) |
The linear actuator has two built-in limit switches, When the linear actuator is fully retracted or fully extended, it will stop automatically.
We can adjust the position of the built-in limit switches during production to meet customer-specified stroke and retraction lengths. For example, specify a stroke of 430mm and a retraction length of 730mm.
Note 1: The specified retraction length must be greater than the original length. For example, a specified retraction length of 730mm is greater than the original length of 700mm.
Note 2: The specified stroke must be less than the original stroke. For example, a specified stroke of 430mm is less than the original stroke of 450mm.

Note:
1. The above data is the maximum load capacity that can be obtained when the linear actuator runs in the vertical direction. If the weight of your equipment (such as a cellar door) is 100kg, and you want to use a linear actuator to open this door, you need to calculate the actual force acting on the linear actuator according to your installation method. This force is usually 2-5 times the weight of the cellar door. If you don't know how to calculate it, please contact us for help.
2. The above is the speed at no load, and the actual working speed will gradually slow down as the load increases. Full load speed is approximately 60-70% of No-load speed.
3. Different speeds correspond to different maximum loads. Please select the right speed according to the speed and maximum load you need.
4. Linear actuators are not recommended for continuous operation under maximum load, we recommend letting it work at about half of the maximum load to get a longer working life.
5. For linear actuators with a stroke greater than 500MM, you should not normally allow them to operate at their maximum stroke under heavy loads. If the actual stroke you want is 600MM, we recommend that you choose a linear actuator with a stroke of 700-800MM.
6. The maximum pull force of the linear actuator is slightly less than its maximum thrust force.
