YBLX-33 series limit switches are improved products mainly used for the end protection of mechanism travel in control circuits of cranes and hoists. The limit switches comply with the GB 14048.5 and IEC 60947-5-1 standards, with protection level of Ip44. They are suitable for AC 50Hz or 60Hz rated working voltage up to 380V and DC working voltage up to 220V. The mechanical life is 60×10 cycles, and the environmental temperature range is -5℃~+40℃ with a relative humidity of no more than 90%.
The YBLX-33 series stroke switch is intended for use in AC 50 Hz or 60 Hz equipment such as hoists, winding machines and other control circuits up to 380 V. It complies with GB 14048.5, IEC 60947‑5‑1 and national mandatory standards.
The manual provides key technical parameters, mechanical life data, environmental limits, and detailed physical dimensions for proper mounting. It also lists model variations and part numbers for different configurations. This manual is written in Chinese.
