Open collector output.  Type code standard Type W2GF-02 (1) (2) (1) Represents a touch switch (2) Represents a series name  Rating/performance Item Rating/performance 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.  Output circuit diagram  Operation chart Capacitance detection Detected Touch switch main circuit Electrode Not detected Output transistor *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. 1 W2GF-02  Exterior dimensions Note: 1. The relationship between the terminal numbers and symbols are shown below. Terminal No. Terminal symbol 2. The housing compatible with the connector shall be Type 51065-040 series made by Molex Japan LLC. Electrode  About usage Type code Brand name * Unless otherwise specified, the dimensional tolerance shall be IT16. [Unit: mm] Terminal arrangement Lot number (1) Usage The touch switch incorporating the specifications required in each application is available by making the electrode of this product come into contact with the Human body (finger) member (made of metal material or metal plated member) for touch switch and fixing it. The through-hole in the electrode allows its attachment with a screw. (2) FG terminal Due to the characteristics of touch switches, static electricity of human body may intrude into a touch switch through the electrode. The FG terminal is provided as the path for discharging the static electricity. To effectively use the FG terminal as anti-static measure, you are recommended to connect the terminal to the area of stable electric potential including the frame ground in the machine with thick and short wiring. When not using the FG terminal, connect it to GND. Touch switch  Precautions for use member Screw Electrode (1) As the touch switch member, use a conductive member including metal member and metal plated member. (2) Be sure to insulate the touch switch member and the electrode of this product from the earthing conductor. (3) Depending on the conditions including the size of the touch switch member and its surrounding metals, the regularly applied capacitance differs. Before using the product, check that the applied capacitance is equal to or smaller than the rated detection capacitance with the touch switch member attached. (4) Do not apply stress that causes the bending of the electrode during use. 2 W2GF-02 3 All sales are subject to Omron Electronic Components LLC standard terms and conditions of sale, which can be found at http://www.components.omron.com/components/web/webfiles.nsf/sales_terms.html ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
