GLA200 12V DC Small Linear Actuator
Custom options are also available, please contact us for more information
The GLA200 is a 12V DC (direct current) linear actuator similar in construction to our GLA750 model, but with a faster extension speed of up to 29mm/s while providing a pushing or pulling force of up to 250N (25kg, 56lbs) at the rated voltage.
This model is currently available in six different stroke lengths (travel distances): 15mm (19/32"), 50mm (2"), 100mm (4"), 150mm (6"), 200mm (8") and 300mm (12").
The travel speed of up to 29mm/s under no-load reduces to 21mm/s under the full rated load.
Please see below for more product details.
The GLA200 is one of our most popular actuator models, used for everything from automatic valves and doors in farms and factories, to electric windows and other home automation projects. The model is externally identical to the GLA750, with the only differences being the gear transmission and lead screw, which are designed to provide a higher speed travel and yet maintain a decent back-driving (load-holding) capacity. The faster travel of this actuator makes it suitable for time-critical applications where the load requirements are smaller.
The operating voltage of 12V DC makes it suitable for powering from a lead-acid battery such as a car battery, or running from a mains to 12V DC adapter which are widely available.
Leads & Connector Options
The actuator comes with a 0.8m PVC insulated lead as standard (black external sleeve with two internal cores, one red and one black) with uncovered lead ends. An option is provided for a DC (barrel type) power connector to be added (2.1mm internal diameter, 5.5mm external) on a 300mm lead, bringing the total lead length to 1.1m. Allow for one extra working day to process your order if a connector option is added, since these are soldered and insulated to-order.
We are able to supply custom wiring and connectors upon request, please contact us with your requirements if interested.
User Advice
To change the direction of travel simply swap the polarity of the DC power source to the two actuator leads (this may be achieved using hardware such as our rocker switch harness or GLA-CU-X3 remote control unit). By varying the input voltage between 0-12V DC it is possible to control the speed of the actuator. Reducing the voltage will also reduce load capacity (for example at 6V the actuator will have roughly half of the maximum load capacity at 12V).
This actuator is designed primarily for compression loads, it will typically work OK in tension, up to the same rated maximum load, but can be more susceptible to damage from overloading. Shock loads through the mounting points should be avoided.
As with any DC motor the motor may be run at a higher voltage than the nominal 12V DC however operation at higher voltages will invalidate the warranty. Experienced users who wish to extract greater power from the actuator (at their own risk) should abide by a practical operation ceiling of 18V, above which the motor, diodes and limit switches of the actuator would be significantly more likely to fail. Be aware that the current draw will be greater if the actuator is run at above 12V DC and the duty cycle should be reduced to help avoid over-heating.
Ensure that the control hardware and power source are capable of providing sufficient current for the loads you expect the actuator to experience. We cannot be held liable for damage caused to connected hardware due to inappropriate hardware selection.
CAD models (STEP, IGS, Autodesk Fusion 360) of the actuator are available upon request. Contact us with the size(s) and file formats that you require and we'll attach the files in return.

Operating Characteristics
| Motor: | 12V DC, up to 35W |
| Operating voltage: | 3-18V (this is the practical operating window, the warranty is voided if operating at above 12V DC) |
| No Load speed: | 29mm/s |
| No Load Current: | 0.8A |
| Full Load Speed: | 21mm/s |
| Maximum load: | 250N/25kg |
| Current for max. load: | 3.2A |
| Stall current: | 5.2A (the actuator should only ever be allowed to stall for short <1s periods) |
| Maximum static load: | 500N (51kg) |
| Noise levels: | < 50dB under no-load < 53dB under full-load |
| Maximum duty cycle: | 40% (this is the maximum proportion of time that the actuator may be in operation for, up to 2minutes during any continuous stretch. The duty cycle should be reduced below 20% for average loads >100N) |
| Life expectancy: | Nominal 40,000 strokes |
Please be aware that there may some variation in the operating performance from actuator to actuator, as a rule-of-thumb allow for a 5% difference above/below the given values. If intending to use two actuators together to drive the same assembly connect them in parallel to the input current and ensure that the driven assembly is rigid enough to transfer forces between the actuators (so as to prevent twisting if one actuator is slightly faster than the other). | |
