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 -10C to +50C. 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, chair, electric equipment, -type equipment, electric sofa, camera stand, camera, etc.Features:This miniature linear actuator is used in industry, agricultural machinery, construction, sweeping vehicles, ships, , and many other applications.It can be replaced by hydraulic and pneumatic products, which is very suitable for saving energy consumption.Specification:Moving distance: 100mmSpeed: 30mm/sInput voltage: 12V DCDuty 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 supply.The motor will not run idly. Cut off the , can stop at any position, with -locking function.Notice:Confirm whether the motor voltage is before . 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 gas, otherwise it will reduce motor efficiency.Positive and negative motorWhen the terminal needs to be soldered, the temperature of the soldering iron is 340C40C. The heating time is within 3 seconds.Do not deform the plastic.Material:Metalcolour:As ShownPackage Contents:1 x 30mm/s DC 12V -type electric push rod 2 x mounting bracketOnly the above package content, other products are not included.Note: Light and different displays may the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
