The SMC LEY16AB-50CMF-R16P1 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 features flexible mounting options with direct mounting in three directions and bracket mounting in three types, allowing for easy integration into various systems. The actuator supports auto switch mounting and provides advanced speed control and positioning with a maximum of 64 points. Users can select between positioning or pushing control, making it ideal for applications requiring the actuator to hold a position against a workpiece. With a positioning repeatability of ±0.02 mm or less and a dust/drip proof IP65 specification, this actuator ensures reliable performance in demanding environments. It is compatible with a range of controllers, including JXC51, JXC61, and others, although some models have been discontinued. The LEY Series also includes an AC servo motor option with high output (100/200/400 W), improved high-speed transfer ability, and high acceleration compatibility (5,000 mm/S²). It features a pulse input type and an internal absolute encoder, maintaining the same high positioning repeatability and IP65 protection. Compatible drivers include LECSA, LECSB(-T), and others, with some models also discontinued.
