The rod is by a DC motor with a lead screw drive. The telescopic rod can only be retracted not rotated.The motor is and negative. For example, if the electrode is stretched and the negative electrode is contracted, you can change the direction of the expansion and contraction by changing it. temperature -10C to and50C. 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 , 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 , which is very suitable for saving energy consumption.Specification:Moving distance: 100mmSpeed: 30mm or sInput voltage: 12V DCDuty : 10 percent technical parameter:Each side of the 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 - function.Notice:Confirm whether the motor voltage is use. If it is a DC motor, then also consider whether the supply current is sufficient.Do not or operate in high temperature or humid environment, do not place in gas, otherwise it will reduce motor efficiency. 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 or s DC 12V -type electric rod 2 x mounting bracketOnly the above package content, other are not included.Note: Light and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is 1-3cm.
