○ KJT-WN series wireless proximity switches bring you more convenience


● There is no need to dig trenches and wire cables, and the cost of cables, labor and engineering cycles are greatly reduced.

● Simplify engineering design and reduce the workload of designers (especially cable routing).

● Affected by natural terrain such as bridges, rivers, and mountains, cables cannot be laid arbitrarily.

● According to the increase of detection points, a private data collection network can be quickly established, with flexible and convenient expansion.

● When a fault occurs, the detection points are concentrated, eliminating the cumbersome tasks encountered in the past such as patrolling along the line.
