Features: This miniature linear actuator is used in industry, agricultural machinery, construction, sweeping vehicles, ships, freight and many other applications. It can be replaced with hydraulic and pneumatic products, which is very suitable for saving energy consumption. Technical parameter: Each side of the push rod contains a limit switch. When the telescopic rod is moving up or down, it automatically disconnects the power supply. The motor will not idle. Turn off the power, it can stop at any position, with self-locking function. The push rod is driven by a DC motor with a worm gear 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. Specification: Travel distance: 100mm; Speed: 30mm/s Input voltage: 12V DC Duty cycle: 10% Temperature -10°C to +50°C.
