THK AC-SX-200 Intelligent Actuator Controller

The THK AC-SX-200 Intelligent Actuator Controller is a legacy motion controller designed to run THK IA Series actuators, delivering precise positioning, motion sequencing, and controlled linear motion for compatible automation equipment. It offers programmable multi-point positioning, motion programming, PC-based parameter configuration, and a digital I/O interface for PLC communication, with homing, position monitoring, alarm diagnostics, and manual jog operation to support automated processes. As part of THK’s discontinued IA Controller Family, the AC-SX-200 remains in service in many older systems, while THK recommends newer THC, TLC, and TSC controller families for new designs; it is compatible with THK IA Series Electric Actuators and is commonly found in automated assembly equipment, semiconductor manufacturing, inspection machines, laboratory automation, packaging equipment, and precision positioning applications.
