Application
- Touch switches for door knobs
- Touch switches for automatic doors
- Input switches for electronic devices
- Input sensors for amusement arcade machines
- Elevator switches
- Security touch sensors
- Seat sensors
Features
- A locking connector securely prevents disconnection of connectors caused by running wires or vibration.
A clear click touch when plugging together ensures a secure insertion. - When used in a large-output transmission station or near a large-sized inverter device,
the common mode noise from the DC power source can be diverted to the frame ground. - Because this is an ultra-small sensor, it can be easily installed locations where space is very limited.
- Open collector output means direct connection to a microcomputer input is possible without any special interface circuit.
- The sensor does not react to objects of small capacitance such as plastic bags or small pieces of luggage.
There is no need to adjust the sensitivity level. - The static electricity generated by human activity is countered by built-in protection circuits.
No additional countermeasures are required. - The sensor features a contact terminal for the touch electrode.
Connection is available by the simple connection of a touch electrode.
International Standards
- Our products do not have overseas safety regulations such as CE mark, UL standard, EN standard etc.
- Products is compliant to the RoHS directive.

Precautions During Use
- Do not apply any voltage greater than 100V peak, between GND and F.G
- The touch (detection) electrode of the touch sensor is connected to the detection circuit.
Accordingly, between the touch sensor power and AC power,
ensure the insulation is sufficient for the breakdown voltage for safety. - When the coupling capacitance between the primary and the secondary power in the DC-DC converter power supply is
1000 pF or less,the capacitance between the primary 0V line and the secondary 0V line should be approximately 1000 pF.
Ensure the capacitor has a sufficient breakdown voltage. - The touch sensor detects the capacitance to ground.If the power source is a battery, connection should be either directly
made with a high current capability of either the plus or minus side to the ground (such as a housing),
or there should be a capacitor fitted of approximately 1000 pF. - The touch sensor uses a high-frequency oscillator circuit.
If multiple touch sensors are approached or the same person touches the touch electrodes of multiple touch sensors,
mutual interference may occur which could reduce detection accuracy. - To prevent mutual interference, models using oscillators of differing frequencies are used.
The influence of mutual interference depends on the arrangement of the touch sensor and touch electrode as well as the
wiring status; consult us for the details.
For the Shifted Frequency types, either B, C, D, or E is included after the model name. - When using the normally open output type, be sure to use the sensor with the wiring capacity of the output line under 1,000 pF. Otherwise, the charge of the output line may exceed the maximum output current at output drive, resulting in output malfunction.
When a longer output wiring is needed for larger output wiring capacity over 1,000 pF, either add a 100 Ω resistor in series besides the output terminal of the sensor side, or use the normally close output type. - For normally open output type sensors, the output line wiring length should be 5 m or less in order to eliminate the influence of the output drive current capability of the IC used in this sensor and the anti-static performance due to wiring inductance.
- If the F.G. terminal is not to be used, open status is required. In this case, the sensor can still be used as a normal touch sensor.
- The tightening torque for the case should be 0.5 Nm or less.
- For other precautions during use, refer to the General Precautions for touch sensors.
