Feeler bar sensor PFD-40
|
Model PFD-40 detects the edge position of running web with touching it and it gives output proportional to the amount of deviation from the neutral.
 - ●Long life through use of a contactless potentiometer.
- ●The feeler is dynamically balanced to a high degree and the vibration is minimum, ensuring well-damped, stable-detection.

Photoelectric sensors RPD / RFD / PTD・70Bseires
|
70B series consists of three different models, photoelectric reflection type RPD-70B, hybrid type RFD-70B by means of reflection and feeler bar and transmission type PTD-70B. Those sensors feed output signals, proporational to the amount of deviation from the neutral position, to a controller to achieve accurate web guiding.

Photoelectric transmission sensor ESD-40
|
Mainly suitable for transparent film. Used for film which can't be detected with normal photoelectric sensor. Also can be used for opaque web.
- ●ESD-40 provides wide detection range of ±6mm, this can be applied to the centering control.
- ●Controller differs according to the actuators used.

Ultrasonic sensor USS-20 |
Model USS-20 detects the edge of web by means of ultra sonic. And stable detection can be obtained without being affected by color and pattern, permeability of transparent film.
- ●Althouth kind of web changes(transparent film, opaque film, paper etc), USS-20 can detect web which intercept sound without adjusting.
- ●The web which has over 10μ thickness can be detected.
