SMC Corporation XT661-4A-L Inductive Proximity Sensor

XT661-4A-L is an SMC non-contact cyclone vacuum pad gripper in the XT661 series, designed to pick up and hold lightweight parts without mechanical contact by applying controlled vacuum. The pad body has a 40 mm outer diameter (Ø40), delivers up to 14 N of lifting force at a vacuum of 0.5 MPa, and uses an M5 x 0.8 vacuum port for connection to a standard vacuum supply; the unit weighs 49 g, making it compact for automation cells. The model designation XT661-4A-L identifies this specific variant within the XT661-4A family, a non-contact cyclone vacuum pad gripper designed for automated handling. Common applications include precision handling of small parts in electronics assembly, packaging, and other lightweight-part tasks where contactless gripping reduces part damage and contamination. Designed for integration with standard vacuum systems, it supports repeatable gripping with minimal part settling and is suitable for automation cells where space is constrained.
