KOGANEI CORPORATION
Koganei Electric Rotary Actuator

Manufacturer: KOGANEI CORPORATION
Features
Maximize efficiency with our advanced compact and thin square form actuators. Because these units feature a lightweight and low-profile design, you can easily integrate them into space-constrained machinery. Furthermore, the long table construction provides a perfect solution for precise pressing control. This design actively improves safety through an integrated fall prevention function with a self-lock mechanism. Additionally, the built-in connector allows you to immediately solve disconnection issues by simply replacing the relay cable. Since the system utilizes open-loop control, it offers a lower-cost alternative to complex linear motors while maintaining extremely quiet operation. Moreover, you can achieve highly flexible performance by easily adjusting stroke, speed, acceleration, and thrust level settings. You can also utilize the table type rotary actuator with its hollow shaft for efficient wiring and piping. Consequently, these versatile actuators work seamlessly with various controllers, including point input and CC-Link remote I/O types. Finally, the configurable swing angle settings and shockless start/stop functions ensure smooth and reliable motion.
