Fife First*Edge SE-38 Digital Sensor

  • All-digital sensor eliminates effects of opacity variations in non-woven materials
  • Unique 180º foldback prism detects materials that are nearly impossible to sense with infrared-only, air or ultrasound
  • Immune to web plane changes and unaffected by ambient light, including sunlight
  • Compatible with all Fife web guide controllers
  • Standard sensing gap of 50.8 mm (2 inches) with a control range of 43.2 mm (1.7 inches)
  • Flexible mounting and positioning assemblies ensure quick and easy installation
  • Electrostatic discharge protected

The SE-38 First*Edge Sensor is an all-digital web sensor specifically designed or materials with varying opacities. Such voids, common with spun bond and loosely woven materials, are often difficult to detect with typical Infrared sensors, and nearly impossible to detect with air or ultrasound.

With its unique 180º foldback prism, the SE-38 is capable of detecting the first edge of a web and then ignoring any and all subsequent variations. It has a standard sensing gap of 50.8 mm (2 inches) and a control range of 43.2 mm (1.7 inches) delivering precise, versatile control for single-edge or center guiding applications.
