WF

WFnext fork sensors are at work in the detection of labels, marks, double sheets, holes, edges, and various objects. Thanks to the design principle that sees both the sender and receiver integrated in a single housing, no adjustment is necessary. This easy-to-use sensor line includes fork widths between 2 mm and 120 mm with fork depths of 40 mm, 60 mm, and 95 mm. Extremely fast response times and fine resolution means that WFnext fork sensors from SICK can even detect small and flat objects, as well as those traveling at high speeds.

Features

  • Infrared light source
  • Simple and precise setting of the switching threshold via IO-Link, teach-in button, or plus/minus buttons
  • Fast response time: 100 μs
  • PNP and NPN switching output
  • Light/dark switching function
  • Stable aluminum housing with IP 65 enclosure rating
  • Smart sensor with integrated IO-Link interface
