This is an LMD series Nema 17 stepper motor linear actuator with stroke 120mm 0.25Nm(35.40oz.in) lead 4mm(0.15748") and sensor. This type of actuator is composed of a highly integrated ball screw linear stepper motor and a guide rail slide. It has the advantages of simple structure and small installation space. Since there is no coupling, its accuracy is higher than that of linear actuators with conventional coupling structures. In addition, the actuator is equipped with a photoelectric sensor for detecting the zero point position. This actuator is widely used in the medical industry, measurement, laser welding, laser cutting, small CNC machine tools, engraving, milling machines, etc.

Limit Switch

Linear actuators from StepperOnline come standard with an NPN photoelectric sensor used as the limit switch.

StepperOnline also supports customization of the sensor, including:

Sensor type (NPN or PNP)
Sensor housing design
Quantity and mounting positions of the sensors

Encoders

StepperOnline supports the custom installation of encoders on linear actuators. Customers can select encoders with or without an index (Z-phase) output, as well as output types such as single-ended or differential (line driver).

Additionally, customers can freely choose from various resolutions to achieve easier and more precise positioning.

All standard StepperOnline encoders are optical incremental encoders. When requesting a custom encoder installation, please provide detailed specifications, particularly regarding resolution, index signal, and output type.

Brakes

To prevent potential hazards in vertical applications or during sudden power failures, StepperOnline supports the installation of brakes on linear actuators to ensure operational safety. StepperOnline uses standard power-off brakes, which engage automatically when power is removed, ensuring secure and stable positioning of the equipment.

Cables

StepperOnline offers cable customization options for its linear actuators, including motor leads, encoder cables, and brake leads. Customization options include:

Lead length and wire gauge
Connector or terminal type
Wire twisting (stranding)
Protective sleeving such as heat shrink tubing, cable glands, or high-flexibility cables
