Linear Actuators - Stepper

20DAM-K Permanent Magnet Stepper Digital Linear Actuator

Permanent Magnet Stepper Digital Linear Actuator

The smallest of our linear actuator motor line, the 20DAM-K is a high-performance captive miniature linear actuator that provides up to 30.6 N of linear force in a 20mm frame size. Mclennan holds stock of various configurations in the UK for immediate delivery. For technical assistance and details of value added assemblies, including wiring / connector options please contact our sales and applications support team.

Motor Highlights
