The GLA650-TRK model offers many unique mounting options compared to our other actuators by employing a track-slider output instead of the more conventional extending-rod outputs.
The sliding bracket (rectangular, white) moves through a distance of 150mm (6") and can move a load of up to 650N (66kg, 146lbs). The no-load speed is 10mm/s, reducing to 6mm/s at the full rated load.
Due to its compact size and flexible mounting profile this actuator is useful for many kinds of home automation and special effects projects.
Please see below for more product details.
This actuator uses the same motor and transmission as the GLA750 model, only instead of a conventional lead-nut with an attached rod this model has a longer rectangular lead-nut (40mm across) with a mounting face on the side. In order for the moving face to be exposed there is a cut-away along the length of the side of the actuator. The end of the body has a fixed steel bracket with a 6mm mounting hole, located where the extending rod would normally go. The rated load capacity for this model is reduced compared to the GLA750 as any load mounted to the white bracket face will be off-set from the lead screw axis.
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.
When mounting a load to the actuator please try to make it as close to the lead-screw axis (centre-line) as possible. Large loads that are off-centre will mean that the friction on the lead-nut is greater and so wear will happen quicker.
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).
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.

|Motor:||Nominal 12V DC, up to 35W|
|Full Load Speed:||6mm/s|
|Maximum load:||650N (66kg, 146lbs)|
|Current for max. load:||3.2A|
|Maximum static load:||1000N (102kg), no more than 50mm offset from bracket|

|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 >300N)|
|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).
