The SMC LEFSH25AA-200B is a versatile electric actuator from the LEFS Series, designed for precision and efficiency. This slider type actuator features a ball screw drive and is powered by a step motor (servo 24 VDC) or a servo motor (24 VDC), making it suitable for a wide range of applications. With a maximum workload capacity of 65 kg and positioning repeatability of ±0.02 mm, it ensures reliable performance in demanding environments. The actuator complies with ISO Class 4 clean specifications, making it ideal for cleanroom applications (11-LEFS only). It is compatible with a variety of controllers, including JXC51, JXC61, JXCE1, JXC91, JXCP1, JXCD1, JXCL1, JXCM1, LECA6, LECP1, LECPA, and LECP6 (note that some models are discontinued). The LEFS Series also offers an AC servo motor option with high output (100/200/400 W), improved high-speed transfer ability, and high acceleration/deceleration capabilities of up to 20000mm/S². The pulse input type and internal absolute encoder (for the LECSB/C/S) enhance its precision, with positioning repeatability of ±0.01 mm for high precision types. Compatible drivers include LECSA, LECSB(-T), LECSC(-T), LECSS, LECSS-T, LECSN-T, LECY, and some discontinued models. This actuator is engineered for high performance and adaptability in various industrial settings.
