4 Inch 100MM Max 8000N Heavy Duty Linear Actuator with External Adjustable Limit Switches – Adjustable Stroke By Magnetic Switch Sensor (Model 0041541-3)

When the red power wire is connected to the positive pole of the DC power supply and the black 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.

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 80 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 330 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 325 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 75 mm.

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.

You need to connect a manual switch or a remote switch to operate the linear actuator.
1) Connect two wires of DC power supply to two terminals <Power> of the manual switch or remote switch.
2) Connect two terminals <Power> of the magnetic switch controller to two terminals <Motor> of the manual switch or remote switch.
3) Connect two wires of linear actuator to two terminals <Motor> of the magnetic switch controller, and you can exchange these two wires to change the moving direction of linear actuator.
4) Connecting two wires of a magnetic switch to two terminals <Magnetic Switch 1> of the magnetic switch controller and connect two wires of another magnetic switch to two terminals < Magnetic Switch 2> of the magnetic switch controller.
Note: The two wires of the magnetic switch cannot be connected reversely, please follow the connection diagram below for specific wiring.

1.The operation by the manual switch:
1.The operation by the manual switch:
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.
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.

2. The operation by the remote switch:
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.
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.

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.

1. This linear actuator does not contain fixed mounting brackets, please click here to purchase. (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.)

2. Compatible Mounting Bracket: Bracket G .

3. This linear actuator is also compatible with two flat mounting brackets: Head Fixed Mount Circular Disk Bracket (Model 0043075) and Bottom Fixed Mount Flat Bracket (Model 0043076) .

4. The front and rear connector style of the linear actuator can be customized: the default is an open hole connector, which can be customized with slotted connector, internal thread connector, etc. And you can provide drawings for customization. If you need customization, please click front connector style and rear connector style to purchase the customized option.

5. Linear actuator fisheye connector can be customized and used in conjunction with the internal thread connector. If you need customization, please click here to purchase the customized option.

6. The orientation of the front and rear connectors of the linear actuator is default; we can rotate them 90 degrees during the production according to the customer's needs. If you need to rotate the connectors 90 degrees, click here to purchase the rotation option.

7. The linear actuator can be equipped with a manual operating device. Even in the event of a power outage, it is possible to extend or retract its telescopic rod using hand tools. If you need a manual operating device to equip the actuator, please click here to purchase it.

8. If you need a power supply to power linear actuator, please click here to purchase.

9. If you want to use a remote control switch to operate linear actuator wirelessly, please click here to purchase.

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.

1. Our store will offer one or two different shipping methods depending on the actual situation of the order. Since we ship from Hong Kong, China to worldwide, import duties will be incurred on the package regardless of which shipping method the customer chooses.

2. For small or lightweight packages, we will select a suitable freight company so that we can pay the import duties on the customer's behalf at the time of shipment. Therefore, the customer will not need to pay any import duties or taxes upon receiving the package.

3. For large or heavy packages, regardless of the freight company we choose, customs will collect import duties and taxes directly from the customer upon customs clearance or upon receipt of the package. The duty amount is usually 20% of the order amount (excluding shipping costs).

4. If the customer wishes us to pay the import duties on the customer's behalf, please contact us when placing the order and pay an additional 20% of the order amount as prepaid duties. We will then pay the duties for the customer.

5. If the customer chooses to pay the import duties themselves, please contact us after paying the duties and receiving the package. We will provide the customer with a discount voucher of a certain amount, which can be used for their next purchase. The discount amount will be the lesser of the import duties actually paid by the customer and 20% of the original order amount (excluding shipping costs).
Please note: We cannot refund cash for import duties paid by the customer themselves. Thank you for your understanding.

6. When the transport company or the customs informs the customer to pay the import duties, if the customer doesn't agree to pay, the package will be returned or destroyed, and the customer will need to bear all responsibility and cost.
