EMLA-50 Electro Magnetic Linear Actuator
Compact 50mm Stroke Linear Actuator for High Thrust Defence Pedestal and Positioning Systems
The EMLA-50 Electro Magnetic Linear Actuator is a compact, rugged linear actuator designed and supplied by System Controls for high thrust linear motion in defence and aerospace pedestal and positioning systems. Delivering 50mm stroke with 800N 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 at 1.1 kg and 164 x 90 x 60 mm, with a drive unit supplied separately, the EMLA-50 is engineered for reliable, repeatable linear actuation in demanding defence platform environments.
What is the EMLA-50?
The EMLA-50 is a highly customised compact linear actuator for high thrust linear motion in pedestal and positioning system applications. The unit is configured with a quill, barrel and drive unit incorporating a suitable motor, gearbox and brake in a single compact assembly. Built-in electronics sense the end positions via limit switches and enable self-locking at any intermediate position, eliminating the need for continuous power to maintain position. Position feedback is available for closed-loop control system integration. A separate drive unit is supplied for driving the linear actuator, accepting a PWM input signal for precise speed and position control. Constructed from aluminium alloy for low weight and high durability, the EMLA-50 delivers 50mm of high thrust linear motion in a 164 x 90 x 60mm package weighing just 1.1 kg.

High Thrust in a Compact Lightweight Package
The EMLA-50 delivers 800N thrust in a 164 x 90 x 60mm aluminium alloy body weighing just 1.1 kg, providing an exceptional thrust-to-weight ratio for compact integration into defence pedestal and positioning systems where space and weight budgets are constrained. The 50mm stroke covers the linear travel range required for elevation, tilt and fine positioning adjustment in surveillance and radar platform applications.
Built-In End Sensing via Limit Switches
Limit switches built into the actuator automatically sense end positions and control power cut-off at the travel limits, protecting the actuator and the platform from over-travel damage. Combined with the self-locking intermediate position capability, this built-in end sensing provides complete travel management without requiring external position sensing hardware.
Self-Locking for Power-Free Position Hold
The integrated self-locking mechanism holds the actuator at any commanded intermediate position without requiring continuous power, ensuring the payload remains securely positioned during power interruptions or standby states. This is a critical capability for defence pedestal systems where loss of actuation power must not result in uncontrolled payload movement.
Aluminium Alloy Construction for Durability
The EMLA-50 body is constructed from aluminium alloy, providing the combination of lightweight construction, mechanical durability and corrosion resistance required for sustained operation in defence and aerospace pedestal environments. At 1.1 kg, it imposes minimal additional mass on the platform while delivering the structural integrity needed for reliable high-thrust linear actuation in field deployed systems.
