Synchronized Linear Actuator systems
The Duff-Norton linear actuator system will allow you to synchronize two linear actuators and control up to another two linear actuators independently. A Duff-Norton linear actuator system includes linear actuators, a controller and a hand set for operation. System applications can include agricultural machinery, industrial automation and outdoor power equipment.

Please do not exceed 10% of 2 minutes continuous use duty cycle with these systems. Exceeding these rates might result in a temporary suspension of service. The system should operate again after a brief cooling period. For synchronized operation please select the Hall Sensor models only. Models with no feedback, or the potentiometer may be used for independent operation, and will require the LTEC kit.

Linear Actuators Controlled Independently

The Duff-Norton linear actuator system will allow you to control up to four linear actuators independently. A Duff-Norton linear actuator system includes linear actuators, a controller and a hand set for operation. System applications can include agricultural machinery, industrial automation and outdoor power equipment.
