Unique 18-mm-dia. Capacitive Touch Switch with Choice of Three Actuators is Activated with Only a Very Slight Physical Contact • 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.
