In the process of hoisting and lowering the spreader, due to the volume and weight of the container, there will be a great mechanical impact, which will easily cause damage to the shell and internal circuit of the inductive proximity switch. In addition, the moment of high power electromagnetic absorption will produce very strong surge impact and radiofrequency electromagnetic field radiation, making the triode in the voltage regulation circuit inside the proximity switch burn out, resulting in the inability to drive the internal circuit and the oscillation circuit.

The high impact resistance and anti - electromagnetic interference ability of the Biduk proximity sensor can well solve the customer's confusion. At present, there is no damage to the inductive proximity switch caused by impact or interference in the application of the front spreader. In addition, the wide working temperature range and extremely high protection level of the shell can meet the requirements for outdoor work, and meet all the environment for field use.
