The LEF series slider type electric actuator features a low profile height of 46mm (LEF16). The actuator's main body can be mounted without removing any exterior components, such as the cover, making installation easy. The standard equipped seal band covers the guide, ball screw and belt, preventing grease and external foreign matter from splashing and entering the LEF. There are 2 types of drivers available, ball screw or timing belt. Available motors include servo motor ball screw drive or step motor belt drive. When the LEF is ordered with the controller, initial data of the actuator is preset in the controller allowing start-up in a short time with the "easy mode".

• Same features and performance as standard LEFS, plus:
• ISO Class 4 / US FED STD 209E Class 10 Clean room
• Built-in vacuum piping with exhaust port for removing generated particles
