The Kinitics Linear Actuator (KLA) is a shape memory-alloy based actuator that uses Bundled Wire technology to deliver high force and actuation speed in a small package. The Kinitics Linear Actuator can be easily configured to supply a pushing or pulling force. Due to the inherent lack of moving parts the actuator requires very little maintenance and produces very little noise. Position control is possible through the addition of a linear sensor while force control is possible through use of a strain gauge.

Potential Applications

Product Selection Chart: This chart shows the relationship between rated force and travel for the KLA05 Kinitics Linear Actuator. Actuator travel, or stroke, depends on the travel modifier incorporated into the actuator, which in turn impacts the allowable operating force. For example, if you require an actuator with 5mm of travel and 300 N of force, you would use the above chart to select the a “KLA05-4O” actuator, indicating a 4mm nominal stroke and the over-travel modifier. These two options would then be used in the configurator below to generate the actuator part number. See the KLA05 data sheet for more details.

Kinitics Automation Controllers

Kinitics controllers simplifies using Kinitics DC Linear Actuators and Piston Pumps by interfacing easily with PLC’s, control switches, relays, and standard I/O cards. Closed- and open-loop control using one or several inputs allows for a high degree of accuracy and repeatability while maintaining the actuator within recommended safety limits.

Kinitics KCD125 Controller

KCD125 | Key Features & Benefits

  • 6-24 VDC input
  • Compact size, DIN rail mounting
  • Internal temperature protection; fault notification
  • Discrete I/O allows for multiple control strategies

KCD125 | Discrete Inputs:

  • Enable: Driving of the actuator is conditional on the presence of a signal at the Enable discrete input.
  • Single: The actuator will stroke from its present position to its End of Travel position limit, triggered by the End of Travel switch input.
  • Pulse: The actuator will stroke from its present position to its End of Travel position limit, triggered by the End of Travel switch input. Once the actuator relaxes to its home position, as indicated by the Home switch, the controller will automatically initiate another stroke to End of Travel. The controller will continue in this manner provided the Pulse signal is maintained. A low-voltage, 100 Hz PWM signal can also be used at the Pulse input for complex control.

KCD125 | Analog Input:

  • Gain: This 4-20ma input allows complex control of a Linear Actuator or Piston Pump to be implemented. Feedback from a position, force or pressure sensor can be used in the PLC programming to adjust Gain as necessary to, for example, lift a part to a certain position or exert a specific force when holding an object.
KCD125 | Discrete Outputs:
  • Status: Indicates that a signal is present at the Enable input, and the controller is not in an over-temperature condition. The Status LED will switch from red to green to indicate that Status is active.
  • Home: Signals the actuator is in the Home position. The optional Home switch must be installed for this output to function.
  • End of Travel: Signals the actuator has reached its End of Travel.
  • Fault: Signals an error condition has caused DC voltage or current to be present at the load when the controller is in the off-state, or there is no voltage/current at the load when the controller is in the on-state.
