Thomson Electrak LA14 DC Electric Linear Actuator

Rugged DC actuator for industrial linear motion

Electrak LA14 is designed for applications where a robust electric linear actuator with DC motor operation is required. It provides reliable extension and retraction for industrial mechanisms, mobile equipment and auxiliary positioning systems.

The actuator can be configured with either an Acme screw or a ball screw drive. Acme screw models are useful when simple, robust and self-locking behavior is required. Ball screw models provide higher load capacity and better efficiency for more demanding applications.

Main features of Thomson Electrak LA14

• 12, 24 and 36 VDC motor options for flexible DC-powered systems.
• Dynamic load capacity up to 6800 N with ball screw versions.
• Static load capacity up to 18,000 N depending on screw type and configuration.
• Stroke length up to 600 mm for medium-stroke industrial mechanisms.
• No-load speed up to 61 mm/s depending on screw type and model.
• Full-load speed up to 37 mm/s with selected ball screw versions.
• 25% full-load duty cycle for intermittent industrial operation.
• Acme screw or ball screw options for different load, efficiency and holding requirements.
• Aluminium cover tube with T-slots for easier mounting of external position sensors.
• Overload clutch and thermal motor protection to help protect the actuator and machine.
• Anti-rotation mechanism for stable linear movement.
• IP65 protection class for sealed industrial use.

When to choose Electrak LA14?

Electrak LA14 should be selected when the application requires a rugged DC actuator for industrial pushing, pulling, lifting, adjustment or positioning tasks. It is a good choice when the machine uses DC power and requires a mechanically strong actuator with practical stroke and load capacity.

• industrial adjustment mechanisms;
• lifting, pushing and pulling applications;
• machine positioning systems;
• mobile equipment auxiliary functions;
• applications where DC motor operation is preferred;
• mechanisms requiring Acme screw self-locking behavior;
• applications requiring higher load capacity with ball screw models;
• systems where external position sensor mounting is useful.

Acme screw or ball screw version?

Electrak LA14 is available with both Acme screw and ball screw drive options. Acme screw versions are typically selected for robust operation, simple mechanics and self-locking behavior. They are suitable for applications where load holding without continuous motor power is useful.

Ball screw versions are selected when higher dynamic load capacity, better efficiency or higher full-load speed is required. The correct screw type should be selected according to load, speed, duty cycle, holding requirement and expected operating conditions.

Electrak LA14 or Electrak LA24?

Electrak LA14 and Electrak LA24 are mechanically similar actuator families, but the key difference is the motor supply. Electrak LA14 is a DC actuator with 12, 24 or 36 VDC motor options. Electrak LA24 is an AC actuator with 230 VAC single-phase or 400 VAC three-phase motor options.

Electrak LA14 is suitable when the machine or vehicle already uses DC power. Electrak LA24 is more suitable when the system is based on AC power and an AC motor actuator is preferred. The final choice depends on voltage, control architecture, available power supply, load, stroke and machine environment.

Mounting, feedback and protection options

The aluminium cover tube includes T-slots that allow external position sensors to be mounted along the actuator body. This is useful when the control system needs position indication or external limit information. Depending on configuration, potentiometer feedback and manual override options can also be considered.

The actuator includes an anti-rotation mechanism, overload clutch and motor thermal protection. These features help protect the actuator and machine in demanding intermittent-duty applications. Correct mounting is still important: side loads should be avoided and the force should be aligned with the actuator axis.

How Inobalt helps select Electrak LA14

Correct actuator selection requires evaluation of the real application, not only the maximum load. Important data includes required dynamic load, static load, stroke, speed, duty cycle, voltage, screw type, mounting position, feedback requirement, operating environment and safety requirements.

Inobalt helps customers select the correct Thomson Electrak LA14 configuration and compare it with other Thomson electric actuator series. We can help evaluate whether LA14 is the right DC actuator for the application or whether another actuator family would be more practical.
