The SMC 11-LEJS63S7A-1500BD-RA is a high-performance electric actuator designed for clean room environments, featuring a high rigidity slider type ball screw drive powered by an AC servo motor. This actuator is engineered with a low-profile design, reducing the height dimension by approximately 36% (32 mm), which contributes to a lower center of gravity. It is capable of handling a maximum work load of 85 kg, making it suitable for demanding applications. With a positioning repeatability of ±0.02 mm, it ensures precise and reliable operation. The actuator supports a maximum acceleration and deceleration of 20000 mm/S², providing rapid and efficient movement. It is compatible with a range of controllers, including LECSA, LECSB, LECSC, and LECSS, offering flexibility and ease of integration into various systems.
