Function and Application
The YBLX-K3 series limit switches are suitable for control circuits with AC 50Hz, voltage 380V, and DC voltage 220V. They are used for travel control of moving mechanisms, change of motion direction or speed, machine tool automatic control, limit action of moving mechanisms, and control of travel or program.
