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.

Model Number	Description	Feature	Feature	Other
See LT models	Actuator	24 VDC models only	Hall Sensor models only (add H suffix to part number)	any capacity or stroke length
TC1-2241-1221	Controller	120 VAC power in - 82" cord	24 VDC power out	1 per system
NA	Actuator Extension Cable 40"	NA	NA	NA
See image above	Handset	partial coiled wire	extends to approx. 7 foot length	1 per system
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.
