The SMC LEY40C-150M-S5AP1D is a versatile electric actuator from the LEY Series, designed for precision and efficiency. This rod type step motor operates on a 24 VDC servo motor, offering a long stroke capability of up to 500 mm. It supports direct mounting in three directions and bracket mounting in three types, providing flexibility in installation. The actuator is equipped with an auto switch for enhanced functionality and allows for speed control and positioning with a maximum of 64 points. Users can choose between positioning or pushing control, making it possible to hold the actuator with the rod pushing against a workpiece. With a positioning repeatability of ±0.02 mm or less, it ensures high precision in operations. The actuator is dust and drip-proof with an IP65 rating, ensuring durability in various environments. It is compatible with a range of controllers, including JXC51, JXC61, JXCE1, and others, although some models have been discontinued. The LEY Series also features a high output AC servo motor with options of 100, 200, or 400 W, improved high-speed transfer ability, and high acceleration compatibility of up to 5,000 mm/S². It includes an internal absolute encoder for precise positioning and is compatible with several drivers, although some have been discontinued. This actuator is ideal for applications requiring reliable and precise motion control.
