Stroke and Length (Model 0041541-2):
Stroke: 100MM.
Retraction Length: When the linear actuator is fully retracted, the center distance between the two mounting holes is 350 mm.
Extension Length: When the linear actuator is fully extended, the center distance between the two mounting holes is 450 mm.

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.

Note 1: The specified stroke must be less than the standard stroke of the ordered actuator. For example, a specified stroke of 85 mm is less than the standard stroke of the ordered actuator (100 mm). In this case, the retraction length will be reduced by an equivalent value, resulting in a retraction length of 335 mm. Of course, you can also choose to retain the original standard retraction length of 350 mm.

Note 2: The specified retraction length must be less than the standard retraction length of the ordered actuator. For example, a specified retraction length of 330 mm is less than the standard retraction length of the ordered actuator (350 mm). In this case, the stroke must also be reduced by an equivalent value, resulting in an effective stroke of 80 mm.

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 Bracket: Bracket G
4. This linear actuator is also compatible with two flat mounting brackets: Head Fixed Mounting Circular Disk Bracket (Model 0043075) and Bottom Fixed Mounting Square Plate Bracket (Model 0043076) .

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.

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.

Production Time & Return or Exchange Policy

The linear actuators are customized and not in stock, and we need to spend 3~7 working days to produce them according to the specified parameters in your order, so that we don't accept returns or cancel orders. If customers order unsuitable linear actuators themselves, we also do not accept exchanges, please understand.
