Edge Sensor

A variety of TK PID sensors are available according to the kind of web or the state of web edge such as feeler-bar type, photoelectric type, ultra sonic type. Accurate and stable guiding capability can be obtained in combination with TK actuator and controller.


PFD-30 is a touch sensor to detect the web edge with filler bar. Detection signal is output continuously whether the deviated much for the neutral, to make more accurate position control of the web.


  • because it uses non-contact potentiometer, long service life.
  • filler bar is located by taking sufficiently dynamic balance, vibration is very small, then the stable detection of the dumping was heard.

RPD / RFD / PTD 70B series

70B Series, the transmission photoelectric, photoelectric reflection, There are three types of dual-purpose type / lever photoelectric reflection, the light receiving element is using the image sensor, respectively. The detection signal, and outputs a voltage proportional to the amount in accordance with the deflection of the web.

Transparent film is mainly for. Transmittance is high, and used in the case that can not be detected by the photoelectric sensor normal. Of course, you can also use the web without going through the light.


  • detection width, and widely ± 6mm, can also be applied to the control center.
  • BLA-11 amplifier, the sensor can also be used to each non-ESD-30. For more information, please contact us.

USS-10 will detect the edge of the web using ultrasound. Colors and patterns, stable detection without being affected by the transmittance of the transparent film is possible in particular.


  • can be detected without adjustment (transparent film, opaque film, paper, etc.) as long as they are for the ultrasonic sound insulation also has changed the type of web.
  • web thickness available is greater than or equal to 10μ.
