Touch Switch
D5C
CSM_D5C_DS_E_4_3
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.
Be sure to read Safety Precautions on page 6 to 7 and
* Malfunction may occur if used in locations subject to water or oil.
Safety Precautions for All Limit Switches.
