GLA1500-N 12V DC Compact High Force Low-Noise Actuator

The GLA1500-N is a compact-bodied and yet high force actuator with a very high build quality. It is capable of providing a pushing or pulling force up to a maximum of 1500N (152kg, 337lbs) with a travel speed of 9.5mm/s under no-load, reducing to 4.5mm/s under the full rated load. A built-in quadrature encoder allows the actuator travel speed (and position) to be accurately measured, which means that two (or more) of the actuators can be synchronised when paired with a suitable controller.
The model has an attractive mix of corrosion-resistant materials used throughout the exterior, including a stainless steel extending rod. Very rarely for an actuator of its size and layout (with motor parallel to the output) the transmission uses two worm-and-wheel reduction stages, making it one of the quietest compact-body actuators available at its force level.
Typical applications include electrically operated doors, hatches, special effects and adjustable furniture.

GLA1500-N (12V)
As with most of our stock actuators this model has built-in limit switches at the ends of travel, meaning the actuator should stop automatically at the fully retracted and the fully extended positions.
Integrated Encoder, for position detection and synchronisation
The actuator has a hall-sensor based quadrature encoder built-in to the motor. The encoder is powered by two of the six cores of the main cable (+Vcc Red, -GND Black) and can run from a DC supply of between 5-12V. It has a dual-channel output (channel A Yellow lead, Channel B White lead), with each channel generating 26.1 pulses per millimetre of travel (4 pulses per motor revolution). One of the channels is out of phase with the other, as such it is possible to tell both the speed (from pulse frequency) and direction (by reading the pulses of one channel and comparing it to the other) of the motor. The nature of the signals that are generated is illustrated below. Given a maximum no-load travel rate of 10mm/s for the 12V motor (when at 12V) the pulse frequency may be up to 261Hz per encoder channel (or the frequency rate may be greater than this if your controller is counting all rising/falling edges as opposed to only HIGH/LOW signal state changes). When used with the appropriate controller the encoder signals can be used for positional control with much greater accuracy and consistency than potentiometer-based actuator feedback systems.
Leads & Connector Options
The actuator comes with a 2m long PVC-insulated lead as standard, this has six internal cores: Blue and Brown (to the motor, thicker wires), Red and Black (positive and negative power to the hall sensor encoder circuit, thinner wires), and White and Yellow (outputs from the encoder, channel 1 and channel 2, also thinner wires). If you are only running a single actuator (don't require synchronised control) and don't need position/speed feedback then you can connect directly to the brown and blue motor leads and ignore the others. The connections are illustrated in the below diagram which also shows the limit switch circuit inside each actuator, in series with the brown and blue motor leads.
Options are provided above for us to add a 6-pin connector (4.2mm pitch, 3x2 format, latched) onto the actuator lead, bringing the total lead length to either 1m or 2.5m. If you have a custom lead length or connector requirement, please contact us.


User Advice

Electric actuators such as this model are low-voltage electromechanical components that are used in a wide variety of different applications. It is important that the safety of each installation is assessed according to its own requirements, construction, end user and environment. Please see a list of design principles on page 3 of the actuator reference sheet (PDF), which we strongly recommend that you adhere to in your end-application design.

Operating Characteristics

Maximum load: 5.7A. If using overcurrent detection to protect the motor, ensure that this is sensitive enough to react quickly to an overcurrent event.
