EMLA-500 Electro Magnetic Linear Actuator
Long-Stroke 500mm Linear Actuator for High Thrust Defence Pedestal and Platform Systems
The EMLA-500 Electro Magnetic Linear Actuator is a long-stroke, rugged linear actuator designed and supplied by System Controls for high thrust linear motion requiring extended travel in defence and aerospace pedestal and positioning systems. Delivering 500mm stroke with 2000N thrust, 0.5mm free play and a self-locking mechanism for intermediate position hold without power, it operates on 24 VDC with PWM signal control and provides position feedback for closed-loop system integration. Built from aluminium alloy in a slender 670 x 55 x 40mm profile weighing 1.6 kg, with a drive unit supplied separately, the EMLA-500 is engineered for reliable long-stroke linear actuation in demanding defence platform applications.
What is the EMLA-500?
The EMLA-500 is a highly customised long-stroke linear actuator for high thrust linear motion applications requiring extended travel in pedestal and positioning systems. The unit is configured with a quill, barrel and drive unit incorporating a suitable motor, gearbox and brake. Built-in electronics sense end positions via limit switches and enable self-locking at any intermediate position without requiring continuous power. Position feedback is available for closed-loop control integration. A separate drive unit accepting a PWM input signal is supplied for driving the actuator. The 500mm stroke in a slender 670 x 55 x 40mm aluminium alloy body at 1.6 kg delivers the extended travel and high thrust needed for elevation, deployment and actuation in larger defence pedestal and platform systems.

500mm Long Stroke for Extended Travel Applications
The EMLA-500 delivers 500mm of linear travel in a slender 670 x 55 x 40mm aluminium alloy body, providing the extended stroke needed for elevation, deployment and positioning in larger defence pedestal and platform systems where the 50mm travel of the EMLA-50 is insufficient. At 1.6 kg, the EMLA-500 remains lightweight relative to its stroke length, minimising the platform weight impact of long-travel actuation.
Built-In End Sensing and Slender Profile
Limit switches provide automatic end sensing at both extremes of the 500mm travel range, protecting the actuator and platform from over-travel. The slender 670 x 55 x 40mm profile accommodates the long stroke in constrained platform mounting configurations where a larger cross-section actuator could not be installed, making the EMLA-500 suitable for integration into tight spaces within complex defence system architectures.
2000N High Thrust for Heavy Platform Actuation
The EMLA-500 delivers 2000N thrust, more than double the 800N of the EMLA-50, providing the force needed for actuation of heavier pedestal assemblies and larger platform components. The 0.5mm free play specification ensures that this high thrust is delivered with minimal mechanical play, maintaining repeatable, precise positioning throughout the actuator travel range.
Self-Locking Intermediate Position Hold
The integrated self-locking mechanism holds the actuator at any commanded intermediate position within the 500mm travel range without requiring continuous power. This is essential for defence pedestal applications where the actuated component must remain securely positioned during standby, power transitions or emergency shutdown conditions without requiring a powered brake or additional holding mechanism.
