Miniature Linear Motion Series · S20
Actuonix Motion Devices unique line of Miniature Linear Actuators enables a new
generation of motion-enabled product designs, with capabilities that have never before
been combined in a device of this size. These linear stepper actuators are a superior
alternative to designing your own push/pull mechanisms.
The S20 actuators are complete, self-contained linear motion devices. Several stroke
length options allow these to fit a wide variety of applications.
The brushless stepper design makes the S20 our highest precision and longest life actuator.
Basis of Operation
The S20 is designed to push or pull a load axially along its full stroke length. The speed of
travel is determined by the step frequency, and maximum force by the current applied.
When power is removed the actuator will hold its position, unless the applied load exceeds
the back drive force. Actuators should be tested in each specific application to determine
their effective life under those loading conditions and environment.
Ordering
Small quantity orders can be placed directly online at www.Actuonix.com. Purchase
orders, volume quotes, and custom order requests can be sent to [e-mail].
MOQ for custom strokes, cables or connectors is typically 500pcs. Each actuator ships with
two mounting brackets and #8-32 mounting hardware. The cable length is approximately
300mm with actuator mating connector and bared leads. The thread in the end of the
round aluminum shaft is M8x1.25.
