Introducing the SMC 11-LEFS40B-950B-S36N1, a top-tier electric actuator designed for clean room applications. This advanced slider type actuator features a ball screw drive and is powered by a step motor (Servo 24 VDC) or a servo motor (24 VDC), ensuring precise and reliable performance. With a maximum workload capacity of 60 kg and exceptional positioning repeatability of ±0.02 mm, it is engineered for high precision tasks. The actuator is compatible with a range of controllers including LECP6, LECA6, LECP1, LECPA, and LECPMJ, although some models may be discontinued. The LEFS series also offers an AC servo motor option with high output capabilities (100/200/400 W), enhanced high-speed transfer ability, and impressive acceleration/deceleration rates of 20,000 mm/S². It includes a pulse input type and an internal absolute encoder for superior control and accuracy. Compatible with controllers such as LECSA, LECSB, LECSC, and LECSS, this actuator is ideal for applications demanding high precision and efficiency.
