KJT analog proximity switch, when a metal object approaches the detection surface of the analog sensor, as the distance changes, it outputs an electrical signal that changes in a linear relationship with the distance, thereby achieving the purpose of detection and monitoring. Wide range of operating voltage facilitates system design. Epoxy resin integrated potting, protection grade IP67, insensitive to dirt, suitable for harsh environments. It can be widely used to measure and control position deviation, bending, and offset; it can measure the amplitude height of oscillation, control dimensional stability, and control positioning, etc.
