Introduction:
This is a linear actuator with adjustable stroke. It is equipped with two external normally closed magnetic switches that can slide freely, and by adjusting the position of these two normally closed magnetic switches, the linear actuator can be controlled to work within the set stroke length. For example, for a linear actuator with a stroke of 500MM, you can set it to move within a stroke range of 150MM to 400MM.

Application:
Mainly used for 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 replace hydraulic and pneumatic products to save power consumption.

Equipped with two external normally closed magnetic switches that can slide freely, by adjusting the position of these two normally closed magnetic switches, the linear actuator can be controlled to work within the set stroke length.
You can control this linear actuator by a manual switch or a remote switch.
Built-in two limit switches, linear actuator will automatically stop when stroke rod reaches the limit position.
Automatically lock after stopping, and no power supply is required.
Maintenance-free

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.
Stroke range: 10 inches or 250 mm
Optional speed: 5±1mm/s, 10±2mm/s, 15±3mm/s, 20±4mm/s, 30±5mm/s, 50±10mm/s, 100±15mm/s, 160±20mm/s
The above is the speed at no load, and the actual working speed will gradually slow down as the load increases.
Max load capacity: 2000N / 200 Kgs / 450 lbs at 5mm/s
Linear actuator can get maximum load capacity when it operates in the vertical direction, and the pulling force is less than pushing force.
No-load current: 0.5~1A at 12V or 0.3~0.5A at 24V
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.
Shaft diameter: 20mm
Mounting holes diameter: 6mm
Housing material: Aluminum Alloy
Stroke rod material: Aluminum Alloy
Gear material: Steel Alloy
Motor type: Brushed DC Motor
Duty cycle: 20%, max 5mins continuous use
Power cable: Ordinary Two-core Wire
Certifications: CE
Environment temperature: -26℃ to 85℃
Operating noise: about 46dB~56dB (Linear actuators with different parameters will have different noise levels.)
IP rating: IP65

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 .

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.
3. If you want to use a remote control switch to operate linear actuator wirelessly, 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.

Wiring:
If use a manual switch to control the linear actuator, do as following:
1. Connect two wires of DC power supply to two power terminals of the manual switch, and you can exchange these two wires to change the moving direction of linear actuator.
2. Connect the linear actuator, two magnetic reed switches and the two diodes to the manual switch, please follow the connection diagram below for specific wiring.

Operation by manual switch:
1. Press and hold the button <UP> on the manual switch: linear actuator extends outward, when it moves to the position of a magnetic switch, the linear actuator will automatically stop.
2. Press and hold the button <DOWN> on the manual switch: linear actuator inward retracts, when it moves to the position of another magnetic switch, the linear actuator will automatically stop.

Wiring for remote switch:
If use a remote switch to control the linear actuator, do as following:
1. Connect two wires of DC power supply to two terminals of the remote switch input.
2. Connect two wires of linear actuator to two terminals <Motor> of the controller, and you can exchange these two wires to change the moving direction of linear actuator.
3. Connect two magnetic reed switches to the limit control terminals of the remote switch, please follow the connection diagram below for specific wiring.

Operation by remote switch:
1. Press and hold the button ▲ on the remote: linear actuator extends outward, when it moves to the position of a magnetic switch, the linear actuator will automatically stop.
2. Press and hold the button ▼ on the remote: linear actuator inward retracts, when it moves to the position of another magnetic switch, the linear actuator will automatically stop.

How to adjust the position of the magnetic switch:
You can use a small screwdriver to loosen the fixing screw of the magnetic switch, then move the magnetic switch to a suitable position and tighten the fixing screw again.
Note: If the positions of the two magnetic switches are reversed, please swap their positions.

Return or Exchange:
The Linear Actuators are the customized products, we need to produce them according to the specified parameters in your order, so that we do not accept returns or cancel orders. If customers order unsuitable linear actuators themselves, we also do not accept exchanges, please understand.

We can provide 3D CAD model files in STEP format for linear actuators. Please contact us by e-mail if you need them.
