11-LEFS Electric Actuator, Slider Type, Ball Screw Drive, Step Motor/Servo Motor, Clean Room

The Clean Room compatible LEF series is a specialized slider-type electric actuator designed for high-precision motion control in cleanrooms. It features a low-profile design and a unique seal band that covers the internal guide and screw to prevent grease splatter or particle contamination. For enhanced cleanliness, the unit includes built-in vacuum piping with an exhaust port to actively remove generated particles during operation. Designed for ease of use, it allows for mounting without removing exterior covers and offers an "easy mode" for rapid start-up when ordered with a pre-set SMC controller.
