*Because there is no reverse connection protection diode built-in, pay careful attention to the polarity of the power supply.

Usage Precautions

1. The touch (detection) electrode of the touch sensor is connected to the detection circuit.
   Therefore, it is necessary to ensure sufficient withstand voltage and insulation between the touch sensor power supply and the AC power supply to ensure safety.
2. All conductors including the wire connected to the terminal No.4 of this sensor detect capacitance, so make them as short as possible,
   Separate from the wiring of the terminals No.1 to No.3 of this sensor so as not to pick up stray capacitance.
   Also, for the same reason, route the wiring for terminal No.4 as far as possible from all other conductors that are insulated from the wiring for this terminal.
   When passing through a restricted opening, where separation is difficult, use a spiral tube with a thickness of 1.5 mm or more of a material with a low relative dielectric constant of 3 or less and connect it to the wiring of the terminal No.4.
3. If the sensor is used near a broadcasting station with high output, or if there is strong common-mode noise in the DC power supply because it is also used for a large inverter-fed device, install a capacitor of 0.1 μF or more to the 0 V line to remove the noise to the FG terminal.
4. A high-frequency oscillation circuit is used in the touch sensor. Therefore, if several sensors get close or if the same person touches the touch lectrodes of several touch sensors at the same time, the detection operation may malfunction due to reciprocal interference. It is recommended to consult with our company since the interference depends on the position and wiring of the touch sensors and the sensor electrodes.
5. 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.
6. 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.
7. The tightening torque for the case should be 0.3 N·m or less.
8. For other precautions, refer to “General Precautions” for touch sensors.
