Công tắc hành trình, công tắc giới hạn LX91-12, LX91-21

• Brand: CHFK

It is used in the circuit of AC 50-60Hz , voltage up to 500V and DC voltage up to 440V . It is used to limit the travel of various mechanisms. It can also be used directly as a 5.5kw three-phase squirrel cage asynchronous motor ( the two-phase fire of the main source ) The limit switch has a conventional heating current of 16A .
Structure and working principle
The outer shell of the limit switch is made of copper alloy. Its outer shell has good mechanical strength and good corrosion resistance. Under the environmental conditions of marine ships, the performance of the material will not deteriorate. The shell type is protection type, and the protection grade can reach IP66 . Due to the spring action, it can automatically reset. Operating position: 45 ° → 0 ° ← 45 °  limit switch contact opening and closing is determined by the cam position. Conform to the standard,
meet the special requirements of IEC377-2 control switch, and pass the inspection of China Classification Society to meet the marine standards.
