June 26th: This model has been replaced with the new and improved GLA1500-N model. The GLA1800 will be available at a reduced price while stocks last.
The GLA1800 model is a small-sized and yet high force actuator capable of providing a pushing or pulling force up to a maximum of 1800N (183kg, 404lbs). Travel speed is 10mm/s under no-load, reducing to 5mm/s under the full rated load.
Typical applications include electrically operated doors, hatches, special effects and adjustable furniture.
Please see below for more product details.
This actuator model provides a greater load capacity than many similarly sized alternatives, it is a variant of our GLA1000 model with a modified transmission to increase load capacity. The body of each actuator is made from a combination of steel and aluminium, which is both plated and painted in parts for increased corrosion resistance.
With a low noise output and small size this model is perfect for powering large electric windows, fold-out steps and other automated features. Operation at 12V DC means that the actuator can be driven from most vehicle batteries or by readily available power adapters. We also stock 8mm-pin steel mounting brackets suitable for this actuator.
The actuator comes with a 0.6m PVC-insulated lead as standard, this has two internal cores, either red and black, or on some units blue and brown, as pictured. The actuator should extend if connecting positive to red (or blue) and negative to black (or brown), swap the polarity to retract.
An option is provided for a DC (barrel type) power connector to be added (2.1mm internal diameter, 5.5mm external) on a 200mm lead, bringing the total lead length to 0.8m. 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.
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-X2 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. Avoid shock or impact loads through the mounting points which could damage the actuator.
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 or IGS) of the actuator are available upon request.
See the technical details tab for more information.
|Motor:||Nominal 12V DC, up to 80W|
|No Load speed:||10mm/s|
|No Load Current:||0.85A|
|Full Load Speed:||5mm/s|
|Maximum load:||1800N (183kg, 404lbs)|
|Current for max. load:||7A (do not apply power to the actuator if the load exceeds the maximum rating, this would void the warranty and be likely to damage the gearbox or bearings)|
|Noise levels:||< 52dB under no-load|
< 55dB under full-load
|Maximum duty cycle:||20% (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 15% for average loads >900N)|
|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).
|Mounting:||Two 8mm holes. One is towards the end of the piston rod, the other is on the rear of the gearbox housing.|
|Body material:||Aluminium, nickel plated and painted steel. Rated to IP65|
|Operating temperature:||-5°C ~ +45°C|
|Gearbox type:||Two-stage low-noise nylon (first stage steel helical to nylon helical, second stage nylon spur gears)|
|Limit switches:||Installed internally at ends of travel (fixed-position). The circuit functions like this:|
|Wire length:||0.6m, excluding optional DC connector cable which brings the total length to ~0.8m.|
