Introduction
Points to note when using the touch sensor
Thank you very much for purchasing the touch sensor.
The touch sensor is a product that has been developed based on our advanced technology and rich experience.
This user manual describes the information necessary for use of the sensor, such as its functions, capabilities and proper
usage.
When using the touch sensor, please keep the following in mind:
・ Only specialists with knowledge of electricity must handle the touch sensor.
・ Please read and understand the contents of this manual thoroughly to use the touch sensor appropriately.
・ Keep this manual handy to refer to it again later on specific problems.

The technical information contained in this manual is prepared only to describe typical performances and
application examples of the product. Application of the products based on the information does not infer the
grant of any OMRON or third party intellectual property, right or license.
1. Preventing malfunction caused by contact with an electric conductor other than a human finger with the touch
2. Preventing operational error
3. Preventing the entry of water or corrosive gases
4. Preventing malfunction caused by noise
5. Preventing direct touching of the electrode
Before using the touch sensor, please contact OMRON’s business development personnel, if necessary, to confirm
Although OMRON makes constant efforts to improve the quality and reliability of its semiconductor products, products
such as this touch sensor may malfunction or break.
product specifications, while also paying attention to using the sensor with a sufficient margin allowed for its ratings
and capabilities, and taking safety measures such as installing safety circuits to minimize hazards in the unlikely event
that a failure of the sensor might occur.
Basically, this product is not designed and manufactured for use in equipment or systems operated under potentially
hazardous conditions. If you intend to use the touch sensor with any of the following systems, facilities or equipment,
be sure to consult OMRON sales personnel or an agent or dealership first:
electrode
(A) Atomic power control equipment, incineration facilities, railroads, aircraft, vehicle equipment, medical
(B) Systems, machines and devices that are potentially hazardous to humans and property.
(C) Other usages that require a high degree of safety.
Because this product measures the electrostatic capacitance of the detector (electrode), the product may
operate if something other than a human finger is brought into contact with the electrode. Therefore, a fail-safe
design is required for use of the product so that it does not cause any functional or safety problem even on
such occasions. Substances, etc., that may cause a malfunction if they are present near to or on the detector
are:
Because this product detects human touch, it may operate if the detector (electrode) is touched only lightly or if
somebody remains nearby. When incorporating this product into a device, check the detection range
thoroughly, and employ measures to prevent the device from malfunctioning caused by operational error.
Especially, if the device is used where children may come into contact with it, provide some safety measure
such as a child safety lock.
If water or a corrosive gas enters the operating part of the sensor (electrode), in the event of a short circuit or
corrosion of the electrode, the sensor may malfunction or its detection sensitivity may be lowered. If the product
is supposed to be used in an environment where this may occur, employ some structure to prevent the entry of
water or gas, and check to be sure in actual operation that the device is protected securely against such an
event.
The product may malfunction if subjected to excessive noise.
Check to be sure that no safety problems are caused by excessive noise.
Do not employ any structure that exposes the surface of the touch electrode to the air and allows somebody to
touch the metal part of the touch electrode directly. Otherwise, the safety of the product may be impaired,
accumulated electrostatic charges may damage the product, or the electrode may corrode. Adopt a structure
that covers the surface of the touch electrode with nonconductive material and does not allow anybody to touch
the metal part of the electrode directly.
The recommended thickness for the nonconductive material is:
･ Water, metal, animals, other conductive materials
appliances, amusement machines, safety devices, and facilities that must comply with the regulations of
administrative agencies and their respective industries.
Resin material (dielectric constant of 2 to 3): no more than 2mm
Glass material (dielectric constant of about 5): no more than 4mm
