Touch Switch
D5C
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.
* Malfunction may occur if used in locations subject to water or oil.

Detection of End of Cloth or Paper
(Detected with indirect ground)
The D5C detects the end of the paper or cloth
when the antenna touches ground.
Detection of Seams in Cloth or Paper
(Detected with indirect ground)
The D5C detects the seam when the antenna
touches ground pole.

Operating Principle
The limit-type Touch Switch
vibrates at a high frequency.
When an object touches the
antenna...
...the oscillation circuit
constant changes,
oscillation stops...
...the switching circuit
operations, and an
output signal is produced.
Use the specified
voltage.

The D5C by itself can directly switch
a load if DC power is provided.
An AC power supply can be detected
and an AC load can be switched.
