In this case, the sensor covers up, choose the output signal transmission with shielded twisted paircable, its performance will be better.
在这种情况下，将传感器罩起来，输出信号选择带屏蔽的双绞线缆传送，其性能会好一点。

RS-485 communication cable in general occasion using twisted pair can be, but under the high requirement of environment can be using tape shielded twisted pair cables.
485通讯电缆在一般场合采用双绞线就可以，但在要求比较高的环境下可以采用带屏蔽层的双绞电缆。

Two types of twisted-paircable are shielded twisted-pair (STP) and unshielded twisted pair (UTP).
