Function and Usage
The YBLX-22 series limit switches are suitable for use in circuits with AC 50Hz or 60Hz, voltage 380V, and DC voltage 220V. They are used as devices to limit the travel of various lifting and transportation machinery, metallurgical plant equipment, and coal and coke equipment.
Detailed Parameters
| Parameter Category | Parameter Item | Parameter Value |
|---|
| Protection Level | | IP52 |
| Rated Heating Current | 20A |
| Rated Voltage | AC-15: 380V DC-13: 220V |
