Introduction:
This linear actuator 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.

Specifications:
Optional working voltage: DC 12V or DC 24V. Unless you only have 12V power supply available, we recommend you choose the linear actuator with 24V working voltage.

Linear actuator can get maximum load capacity when it operates in the vertical direction, and the pulling force is less than pushing force.

Full load current: 3~6A at 12V or 1.5~3A at 24V
Please use a 12V/6A or 24V/3A power supply to power a linear actuator or use a 12V/10A or 24V/5A power supply to power two linear actuators, or use a 12V/20A or 24V/10A power supply to power four linear actuators.

Fixed Bracket:
1. This linear actuator does not contain fixed mounting brackets, please click here to purchase.
2. Each linear actuator would require two mounting brackets, one to fix the head of linear actuator and another to fix the bottom of linear actuator.
3. Compatible Mounting Brackets: Bracket A and Bracket C .
Operation:
The electric linear actuator has a five-core cable.
1. The red and black lines are two power lines of the electric linear actuator.
Connect the DC power supply to two power wires of the electric linear actuator. When linear actuator is connected to DC power supply, the stroke rod will extend outward; after switching the power in the reverse direction, the stroke rod will retract inward.
The direction of movement of the stroke rod can be changed by switching the polarity of DC power supply.
2. The white, blue and yellow wires are three output wires of the potentiometer.
The blue and yellow wires are connected to two terminals of the potentiometer, it is a fixed resistance value.
When the linear actuator moves, the resistance value between white wire and yellow wire or white wire and blue 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 white and blue wires will decrease accordingly, and the resistance value between white and yellow wires will increase accordingly. When the linear actuator is retracted inward, the resistance value between white and blue wires will increase accordingly, and the resistance value between white and yellow wires will decrease accordingly.
For example, a linear actuator with a stroke of 200mm and a built-in potentiometer of 10K ohms.
When the linear actuator is fully retracted, the resistance value between white wire and yellow wire is 0.8K ohms, and the resistance value between white wire and blue wire is 9.2K ohms.
When the linear actuator is extended to the 100mm position, the resistance value between white wire and yellow wire is 4.5K ohms, and the resistance value between white wire and blue wire is 5.5K ohms.
When the linear actuator is fully extended, the resistance value between white wire and yellow wire is 9.1K ohms, and the resistance value between white wire and blue wire is 0.8K ohms.
Note:
1. If you want to control 2 or 4 linear actuators fully synchronously, you need to add built-in hall effect sensor to each linear actuator, and buy a synchronization controller, please click here to purchase.
2. If you need a power supply to power linear actuator, please click here to purchase.

Different no-load speeds and corresponding maximum thrust:
| No-load Speed | Maximum Thrust |
| 5mm/s | 2000N / 200 kg / 450 lbs |
| 10mm/s | 1000N / 100 kg / 200 lbs |
| 15mm/s | 800N / 80 kg / 180 lbs |
| 20mm/s | 700N / 70 kg / 160 lbs |
| 30mm/s | 500N / 50 kg / 110 lbs |
| 50mm/s | 300N / 30 kg / 60 lbs |
| 100mm/s | 150N / 15 kg / 30 lbs |
| 160mm/s | 100N / 10 kg / 20 lbs |
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. When the speed of the linear actuator is 100mm/s or 160mm/s, the self-locking force is much smaller than the thrust. At other speeds the self-locking force is greater than the thrust.
7. The maximum pull force of the linear actuator is slightly less than its maximum thrust force.
