Miniature linear actuator Johnson motor Saia motor

Saia-motor for positioning, opening/closing or dosing

The new 20mm UAL linear actuator is a small powerhouse. With a resolution of 21 µm per full step, it has a constant force of up to 30 N over the full travel range of 15mm. The compact housing, with a 20mm external diameter, is supported by a direct cable outlet.


The design of the actuator can be engi-neered as a bipolar or unipolar stepper motor, as well as a synchronous motor (max. 50 Vac.). The flexible manufactur-ing of the actuator allows a customer-specific mounting flange and a tailor-made layout design to meet all customer needs. Therefore, the linear actuator has the best preconditions to be used in posi-tioning units, valves and dosing pumps, for example in medical technology or in locking systems.
