Feeler Bar Type Sensor

– PFD-40

PFD-40 is a contact type sensor that detects the web edge position with a feeler bar. The detection signal is used to continuously output the degree of deviation from the neutral position to control the web with higher accuracy.

Photoelectric Transmission Type Sensor

– PTD-70B

PTD-70B is a transmission type edge sensor that detects the web edge position without making any contact. The detection signal is used to continuously output the degree of deviation from the neutral position to control the web with higher accuracy. Also, the detection method can be selected between edge detection and bit count mode.

Photoelectric Reflection Type Sensor

– RPD-70B

RPD-70B is a reflective type edge sensor that detects the web edge position without making any contact. The detection signal is sent to the control unit as an output signal from a proportional voltage according to the deviation of the web. The detection range is ± 13mm and smooth control is possible.

Feeler Bar/Photoelectric Reflection Type Sensor

– RFD-70B (Changeable)

The RFD-70B is basically the same as the RPD-70B type, but by adding a feeler bar, it can be used both as a reflection type edge sensor and a feeler type edge sensor.

Ultrasonic Type Sensor USS-20

– USS-20

USS-20 detects the edge of the web using ultrasonic. Especially for transparent films, stable detection is possible without being affected by color or pattern transparency.

Photoelectric Transmission Type Sensor (for high transparency films)

– ESD-40(PCDA-80A)

Mainly for transparent films. Used when transparency of the film is high and cannot be detected by ordinary photoelectric sensors. This sensor can also be used for opaque webs.
