Position sensors

Each web guiding action requires the acquisition of the lateral position of the running web.

Infrared edge sensor FR 45

The digital infrared edge sensor with a CCD line chip detects very precisely the position of web edges of homogeneous, opaque webs such as paper, nonwovens, wovens or knits. Its main area of application is on the small pivoting frames series DRS 12/22 for narrow web applications.

Sensor measuring range +/- 3 mm
Integrated blower for dust particles

E+L Database Details

Infrared edge sensor 50

The digital infrared edge sensor with a CCD line chip detects very precisely the position of web edges of homogeneous, opaque webs such as paper, nonwovens, rubber, tire cord, wovens and knits. Transmitter and receiver are located in the same housing, there is no mechanical connection between sensor and reflector.

Sensor measuring range +/- 10 mm
