Safety Precautions
Please read the matters of agreement when ordering
1. How to use
By connecting and fastening this electrode to a touch electrode
(conductive material made from metal or with a metallic plating), a
touch sensor configuration can be created with specifications that
suit your application. The electrode features a hole that enables it
to be fastened with a screw, etc.
2. FG terminals
Static electricity from the human body, etc., is capable of entering
the touch sensor via its electrode. When anti-static measures are
required, select a model (W7ED-12F or W7ED-12L) with an FG
terminal, which acts as a discharge circuit for static electricity. To
enhance the anti-static effects of the FG terminal, we recommend
connecting the FG terminal to a stable potential on the device’s
frame ground using a thick, short wire.
1. Use a touch electrode made of conductive metal or metal-plated
material.
2. Make sure to insulate touch electrode and electrode of this product
from external grounds.
3. The level of capacitance normally applied will depend on
conditions such as the size of the touch electrode or the existence
of metal around the touch electrode. Make sure to confirm that the
touch sensor operates by applying human touch to the touch
electrode with the touch electrode secured in place while in
contact with the electrode of this product.
4. Avoid use in locations subject to direct contact with liquids such as
water. Failure to do so will result in malfunction.
