Working Principle 

The Linear actuator is a device that converts the rotational motion of a low voltage DC motor into linear motion – that is push and pull movements. The electric linear actuator consists of a motor, a gear and a spindle including a nut. A special version of the linear actuator is the built-in actuator meant for integration in a customer guidance. A complete actuator system solution includes one or morelinear actuators, a control box and a control device to operate the actuator

Advantage

The linear actuators are finding their way into a wide range of applications. When something needs to be raised, lowered, pushed, pulled, rotated, positioned, lifted, shifted or moved, the linear actuators are making an irrefutable case for electrification. These actuators operate more simply, efficiently, cleanly and quietly. And with fewer components to act up or wear out, the linear actuators offer exceptional durability. Despite being perceived as costing more, the actuator actually nets out to be more cost-efficient because of savings on several fronts.

Application

The actuators are used in many different industries, making both work and private life easier for a lot of people. The actuators are ideal for hospital beds, patient lifts, dental chairs, bath lifts and wheelchairs.

• Material: Aluminum alloy
• Load capacity: 1200N (122Kg)
• Input Voltage: 12V DC
• Speed: 12mm/s
• Stroke Length : 700mm
• Working frequency: 10-20%
• Built-in limit switches

Technical Parameters:

• Rated power: 20W, maximum 30W.
• Push bar Each side contains a travel limit switch. When the telescopic bar runs to the top or to the top, it will automatically disconnect the electricity.
• The motor will not idle. Cut off the power, it can be stop at any position, with self-locking function.
• The push rod is driven by a DC motor with a screw drive. The telescopic rod can only be retracted without rotation.
• The motor is positive and negative. For example, if the positive electrode is stretched and the negative electrode is shrunk, the telescopic direction of the rod can be changed by changing it.
• Ambient temperature -40°C to +65°C.
• Standard protection class: IP54.
• Low noise design, noise level less than 55dB.
• Please do not disassemble the machine.
• Product features: drive other objects to push, pull, rise, drop.

• Installation size:

  1. The center distance between the two mounting holes before and after the push rod is fully retracted, the mounting distance of the push rod (that is, the length of the push rod itself).

  Below 300mm stroke L (mounting dimensions) = 105mm + S (stroke) 300mm and 300mm above travel L (mounting dimensions)=155mm+S (stroke)

  1. Center distance between the two mounting holes before and after the push rod is fully extended.

  (Below 300mm stroke) = 105mm + S (stroke) + S (stroke) (300mm and 300mm strokes or more) = 155mm + S (stroke) + S (stroke).

  Notice:

• Before use, first recognize whether the motor voltage is correct. If it is a DC motor, then also consider that the power supply current is sufficient.
• Do not store or operate in high temperature or humid environment, and do not place in corrosive gas, which will reduce motor efficiency.
• When soldering is required on the positive and negative power supply's motor terminals, the soldering iron temperature is 340°C±40°C. Within 3 seconds of heating time.
• Do not deform the plastic.
• When installing the motor, pay attention to whether the screws are too long and the company must not over-press the long screws to the parts inside the motor.
