The push rod is driven by a DC motor with a lead screw drive. The telescopic rod can only be retracted but not rotated. The motor is positive and negative. For example, if the positive electrode is stretched and the negative electrode is contracted, you can change the direction of the rod's expansion and contraction by changing it. Ambient temperature -10°C to +50°C. Standard protection level: IP54. Low noise design, the noise is lower than 50dB. Please do not disassemble the machine. Product features: drive other objects to push, pull, raise and lower. Product application: TV lifting table, massage table, electric bed, medical chair, electric equipment, Micro-type equipment, electric sofa, camera stand, camera, etc.<br><br>Features: This miniature linear actuator is used in industry, agricultural machinery, construction, sweeping vehicles, ships, cargo, and many other applications. It can be replaced by hydraulic and pneumatic products, which is very suitable for saving energy consumption. Specification: Moving distance: 100mm Speed: 30mm/s Input voltage: 12V DC Duty cycle: 10% technical parameter: Each side of the push rod contains a travel limit switch. When the telescopic rod runs to the top or to the top, it will automatically disconnect the power supply. The motor will not run idly. Cut off the power, can stop at any position, with self-locking function. Notice: Confirm whether the motor voltage is correct before use. If it is a DC motor, then also consider whether the supply current is sufficient. Do not store or operate in high temperature or humid environment, do not place in corrosive gas, otherwise it will reduce motor efficiency. Positive and negative motor When the terminal needs to be soldered, the temperature of the soldering iron is 340°C±40°C. The heating time is within 3 seconds. Do not deform the plastic.
