Description

If you are looking for a Micro Actuators that's very quiet then the FIRGELLI® Silent Micro Linear Actuator is an ideal choice. It packs a force of 100N (22-lbs). These Actuators use a planetary style gearbox which allows them to be ultra-quiet and offer very smooth efficient linear motion. The in-line design comes without a Clevis on the Motor end but instead has a built-in mounting base place along the main body with pre-drilled holes for easy mounting. This attachment style means that the length to stroke ratio is shorter so that they can fit into tighter spots.  The moving end of the Actuator has a tough plastic Clevis style fitting that can be rotated to any angle. 

These Micro Actuators are very popular in HVAC systems for opening and closing flaps and vents and also in Home Automation applications where secret doors, drawers, and panels are required to be opened and closed remotely. But they really can be used for many applications where noise or space is important. 

Mounting Points

Mounting these Micro Actuators is very simple. The moving end of the Actuator has a clevis hole with a 4.2mm dia so that a 4mm screw can be used to secure them, as well as a 5mm wide slot that's 8mm deep for plate mounting options. In addition, the moving end shaft of the Micro Actuator is able to rotate up to 180 degrees to give you more flexibility with installation and also offer positional flexibility. The End clevis is screwed into the Aluminum shaft that can also be used to adjust the length for very fine installation control. Secondly, the Insert can be removed as it is a threaded insert so that you can install your own clevis end fitting if desired.  

Mounting the Body of the Actuator is the best option for this Actuator as it comes with 4x M4 threaded holes and the base plate has rubber pads for reducing the vibration and noise to the mounting fixtures. The benefit of using the 2 round clevis holes of the Actuator is that the Actuator is able to rotate and swivel as its moves which is likely for a lot of applications. 

Control Options:

These Micro Actuators are a simple 2 wire configuration, this means that you simply supply a 12v DC power source to make the Actuator move, and reversing polarity will change its direction. Most people use a Rocker-Switch to perform this action, or perhaps a remote control system that has 2 buttons (Up and Down)
