GLA700-N 12V DC 800mm Travel Linear Actuator

DISCONTINUED  This model has now been replaced by the GLA800-N model which offers many improvements over the GLA700-N 
Custom options are also available, please contact us for more information

The GLA700-N model is a long-travel yet compact-bodied actuator with a stroke length of 800mm (31.5").

Typical applications include automating greenhouse windows and skylights, as well as access hatches and furniture. Each actuator may provide a pushing or pulling force of up to 700N* (71kg, 157lbs) and a travel speed of up to 13mm/s when under no-load.

You may recognise a similarity with the GLA600-S model actuator, that is because this actuator shares the same type of body but with a different motor and transmission inside.

*A 700N maximum capacity is with a fully X-and-Y-axis supported load (no bending forces across the extending piston-rod). If the load is not independently supported against bending then the load rating should be reduced, down to 350N for a load with up to 100N across the end of the shaft. When the piston-rod is fully extended the proportional length of support provided within the actuator body is small which makes this actuator more susceptible to bending forces than shorter-travel actuators. Use of drawer slides or other sliding supports can ensure that the full load capacity can be utilised. 

The long travel distance provided by the GLA700-N makes it particularly useful for automating 'expandable' features, as such it has been used before in travel beds, caravans and food vending carts. 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-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. 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) of the actuator are available upon request.

Operating Characteristics
Motor:Nominal 12V DC, up to 35W
No-load speed:13mm/s
No-load Current:0.8A
Full Load Speed:8mm/s
Maximum load:700N (71kg, 157lbs)
The maximum load should be reduced if the load is not supported in an axial direction, parallel to the movement of the actuator. Longer-travel actuators are affected to a greater extent by off-axis loads.
Current for max. load:4A
Maximum static load:1000N (102kg) in compression, 700N (71kg) in tension
Noise levels:< 50dB under no-load
< 55dB under full-load
Maximum duty cycle:25% (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 >350N)
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 faster than the other). If your assembly is not rigid or needs to stay level with uneven loads (e.g. tabletop surfaces rising/falling level to the ground) then please get in contact to discuss automatic synchronising control options.
