W2GF-02 Type
Touch Switch with FG Terminal
 Features
 Built-in type ideal for touch detection in gaming machines.
 Touch switch appropriate for each application becomes available
only by attaching product electrode to conductive member with
screw.
 Use of FG terminal allows easy prevention of static electricity
intruding from human body to electrode.
 Compatible with 5 to 15 DCV. Open collector output.

Detection
capacitance (*1)
25 ± 5 pF
Electrical rating
5 DCV (-10%) to 15 DCV (+10%)
Output
Open collector (Maximum output current: 50 mA)
Way of operation
When capacitance detected (Presence of human body contact): Output
transistor ON
When capacitance not detected (Absence of human body contact):
Output transistor OFF
Current consumption 10 mA or less
Effect of voltage
Within the range of ±10% of the rated power voltage, the rate of change
in the detection capacitance must be within ±10% relative to the
detection capacitance provided at the time of the rated power voltage.
Effect of temperature Under operation within the specified ambient temperature range, the
rate of change in the detection capacitance must be within ±10%
relative to the detection capacitance provided at 23 deg C.
Ambient temperature
When in use: -10 to 60 deg C (must be free from freezing or
condensation)
When stored: -20 to 70 deg C (must be free from freezing or
condensation.)
Ambient humidity
25 to 85% RH
*1. Detection capacitance refers to the capacitance value that triggers detection when the path between the electrode and GND terminal of
the touch switch circuit is electrically charged.

*2. You are recommended to connect the FG terminal to the area of stable
electric potential including the frame ground in the machine. When not
using the FG terminal, connect it to GND.
