Antenna
The Limit Touch Switch
constantly emits a high
frequency. If an object
comes in touch with the
touch antenna, ..
Switching circuit
will operate and
send out output
signals.
Constants of the
oscillation circuit
will change and
oscillation will stop.
Applicable to a variety of
purposes in combination
with a dedicated sensor
