A:What is a linear actuator? In which fields is it primarily used?
Linear actuators are drive devices that convert the rotational motion of an electric motor into linear motion, enabling actions such as pushing, pulling, lifting, and tilting through the extension and retraction of the actuator. Our products are primarily used in four major fields: Smart Home (Electric Beds, Recliners), Medical Care (Hospital Beds, Nursing Beds, Surgey Tables), Smart Office (Height-Adjustable Desks, Height-Adjustable Workstations), and Industrial Automation (Agricultural Machinery, Construction Vehicles, and Automated Equipment).
A:How do you select the thrust and stroke of Linear actuators?
The selection of thrust and stroke depends on the load requirements and range of motion for the specific application. Our Linear actuators offer thrust ranges from 1,500 N to 10,000 N and stroke ranges from 20 mm to over 600 mm. When selecting a model, we recommend taking into account factors such as equipment weight, frequency of use, installation space, and operating environment. Our product managers are available to provide professional selection advice.
A:What are the functions of control boxes and controls?
Control boxes serve as the control centers of the actuator system. They convert commands from the controls or sensors into precise actuator movements, enabling either independent single-channel control or synchronized multi-channel operation, while also incorporating safety mechanisms such as overload protection and overheat protection. The controls are the end-user input devices; users use them to send commands to the control box, which then drives the actuators to perform various actions.
A:What is the function of a Hall sensor? Can it be customized?
Hall sensors provide real-time feedback on the actuator’s stroke position and operating status via pulse signals, enabling the customer’s control system to achieve precise closed-loop control and position memory functions. All of our actuator products support optional Hall sensors, and we can customize the sensor accuracy grade and communication protocol according to customer requirements.
A:What safety features do Linear actuators have?
Our linear actuators come standard with an obstacle detection and retraction feature; when the actuator encounters an obstacle during operation, it automatically stops and retracts in the opposite direction, effectively ensuring the safety of both users and equipment. Control boxes incorporate multiple safety mechanisms, including overload protection, overheat protection, and short-circuit protection; under abnormal operating conditions, they automatically cut off the output or reduce power output.
A:What is the difference between medical-grade linear actuators and household-grade linear actuators?
Both serve the same function, but the key difference lies in the grade of their drive systems. Medical-grade linear actuators feature a higher protection rating (IPX6 or higher), more rigorous durability testing standards, and a longer design life. They comply with the IEC 60601-1 safety standard for medical electrical equipment and are capable of withstanding the high-frequency, high-intensity usage demands of healthcare settings.
A:How do you choose the protection rating for a push rod?
Our actuator products offer a range of protection ratings. For residential applications, the basic protection rating is available; for medical applications, we recommend IPX6 or higher, which can withstand frequent cleaning and disinfection; for industrial and outdoor applications, IP66 or higher is available, providing protection against the ingress of dust, moisture, and oil. The specific model should be selected based on the frequency of cleaning and the degree of exposure in the intended environment.
A:What are the different ways to install adjustable-height desk frames?
Our office desk frames support both standard and inverted installation methods, accommodating various desk frame designs. The quick-assembly desk frames feature a minimalist three-step assembly process—the side panels, upright posts, and base feet all incorporate quick-assembly designs, allowing for assembly without the need for complex tools. The desk frame crossbars are telescopically adjustable to accommodate different tabletop widths; the desk legs are available in a variety of tube shapes, including rectangular, square, round, and oval.
