Touch Switch D5C

• Only a slight activation force is required, enabling detecting micro deflections, thin wires, or thin-plate conductors (e.g., steel or stainless).

Application possible for non-conductors by indirectly connecting to ground.

• Instantaneous operation upon contact with extremely limited hysteresis for high-precision position detection.

• Diameter of only 18 mm with standard built-in amplifier, operation indicator, and sensitivity adjustment.

• Conforms to IEC IP67 *

• Freely replaceable antenna with screw mounting.

• Free attachment to enable changing the antenna shape according to the application.


* Malfunction may occur if used in locations subject to water or oil.
