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
- Handles of Pachinko machines
Features
- In various situations that expose amusement arcade machines to static electricity, such as lengthy internal wiring and/or no grounding connection from the machine to the parlor, this sensor assures excellent anti-static performance. This has been realized by optimizing the design of noise eliminating circuit (see the next page) of the sensor, from which the static electricity enters.
- 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 capacitances such as plastic bags or small pieces of luggage. There is no need to adjust the sensitivity level.
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 contact terminal (touch electrode) of the touch sensor is connected to the detection circuit. Accordingly, for safety, between the touch sensor power and AC power, ensure the insulation is sufficient for the breakdown voltage.
- The static electricity discharged to the touch electrode is released from the GND line. The F.G. line smoothens the voltage in the GND line, enabling to control the voltage fluctuation in the GND line.
The GND line and the F.G. line need to be as short as possible, or the impedance should be as small as possible. - 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, the letter B 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.
- For other precautions during use, refer to the General Precautions for touch sensors.
