Fast Linear Actuator

At 5 V DC with a 0.2 A protection current the actuator belongs to the 1 W class of loads (5 V × 0.2 A, calculated), and it belongs there for about one second per movement. Inside a camera, a dispenser or a control panel that already runs a sensor, a radio and a display, that is a load the existing rail absorbs without a dedicated supply, a boost converter or a second cable run - and an internal 5 V part does not force the finished product to expose a higher-voltage path inside an enclosure the user can open.

Control is deliberately primitive, and that is a feature rather than a limitation. Two leads, positive and negative, reverse direction; the drive voltage sets the speed; the automatic stop at the end of the stroke means there is no encoder to read and no position loop to tune. Any board that can drive a small DC motor in both directions can drive this rod.

Two specifications decide whether this rod is acceptable in a product that sits in a room with people. The ≤50 dB noise figure is the one listed for this model and across the KT0905 series, and the movement helps it: the rod is screw-driven rather than impact-driven, the drive stops itself at the end of the stroke so nothing rattles against a stop, and the 9 mm/s speed is quick to the eye while still slow enough that the guide, not the motor, sets the sound level. The IP56 protection level describes a body that keeps dust out and tolerates water jets, which is the class of exposure this actuator meets on a device with an exposed face.

Two limits belong next to those strengths, because buyers check them. The noise figure is published without a measurement distance or mounting condition, so sound in a finished housing still depends on how the actuator is clamped and how stiff the surrounding cover is. And IP56 is a rating for this actuator as a component: it does not make a finished camera or appliance waterproof, because the final protection of a product is decided by its housing, gasket and seals.

This model carries the letter H, which in the KT0905 series means the fast version. The letter L on the same 10 mm stroke means the thrust version. The mechanical envelope is shared and the choice between them is a single trade: speed against force.

The KT0905 family is made by the electric actuator division that KABASI set up in 2021, alongside an industrial electrical business that has been running since 2015, and the plant that machines the 304 stainless steel and copper alloy parts also inspects the finished rods before they are packed. Production and inspection run on dedicated equipment, and the instruments used are listed on the testing equipment page; see that page for the details. The patent and certificate position is set out under certification, the background of the manufacturer is on the about us page, and the service commitments behind an order are collected under why us. For a buying team, the useful point is not the certificate list itself but the fact that the dimensional and force figures on this page come from the same line that ships the parts.
