Stepper Motor Linear Actuator, 400mm Stroke, 700N

This 400mm stepper motor linear actuator delivers precise linear motion with a load capacity of up to 700N. Powered by a 2-phase stepper motor and housed in a durable aluminium assembly, it offers controlled movement at speeds up to 8mm/s under no load. It is ideal for makers, engineering students, and hobbyists designing custom automation rigs or robotics projects.

Precise stepper control

The actuator is driven by a 2-phase stepper motor featuring a 1.8-degree step angle (200 steps per revolution) and 5 kg.cm holding torque, providing accurate positioning across its entire 400mm stroke.

Durable mechanical build

Constructed with an aluminium outer tube and stroke rod, the unit is rated IP43 for ingress protection and weighs 1.29kg with a 10% duty cycle rating.

Driver and power requirements

The integrated motor operates at 2.8V and 1.68A per phase. An external stepper motor driver, such as an M542, is required and operates from a 12V to 24V DC power supply input.

Dimensions and reach

The installation size is 505mm when fully retracted and reaches a maximum extended installation length of 905mm.
