Model HTD-20 Touch switch - Panel installation type -

Application

  • Touch switch for door knobs
  • Elevator switch
  • Input switch of entertainment equipment
  • Input switch for electric devices

Features

  • Does not operate by mistake when touched by an object with small electrostatic capacity such as plastic objects or bags.
  • Fixed sensitivity to avoid the need for troublesome settings.
  • Can withstand human static electricity without any external connection.
  • Does not use any contact point to prevent poor contact problems and increase the lifespan.
  • Normal type outputs the signal only when you have touch.

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.

Usage precautions

  • Do not apply excessive force when installing the HTD-20 to the panel. Otherwise, it may malfunction.
  • When using two or more of the same product aligned together, place them separated by at least the distances indicated in the figure below, or use standard products and products with a different frequency alternately to prevent interference.
    (B or C is added at the end of the model names of different frequency sensors.)
    HTD-20_L20_Usage_precautions.gif
  • 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.
  • 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.
  • 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 electrodes 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.
  • See Touch sensor general usage precautions for other precautions.
