Sick WTV4-3N1171 Overview



PHOTOE.PROX.SWITCH

Sick WTV4-3N1171 Description



  • Scanning distance 4 - 50 mm
  • Reliable detection of planar, highly transparent and reflective objects at distances of 20to 25 mm
  • 5-speed potentiometer for precision setting
  • Large, homogenous light spot
  • Robust plastic housing with metal inserts and inner thread
  • IR versions available for detection of jet-black objects
  • Versions available with linear light spot
  • Your benefits

  • Low-cost machine design as reflective and transparent objects are scanned directly making design time required for a reflector or through-beam system superfluous.
  • The WTV4-3 saves time when mounting and commissioning machines as no alignment is required
  • Robust mounting due to M3 threaded metal sockets for a long service life.
  • Reliable detection thanks to best-in-class background suppression and high resistance to extraneous light
