Sick WT34-B400S04 Overview



Photoelectric proximity switch WT34-B400S04 PNP/NPN, Light/Dark switching selector, Plug M12, 4pin, Test input small light spot

Sick WT34-B400S04 Description



  • Precise background suppression at long ranges
  • Immune to ambient light and crosstalk from another sensor
  • Switch selectable PNP or NPN output and light/dark switching
  • Versions with DC voltage (10...30V) or universal AC/DC voltage (12 240 V DC / 24 240 V AC)
  • Optional test input, adjustable ON and OFF time delays, alarm output
  • M12 or terminal chamber connection: 90 rotatable
  • UL approval

    • Your benefits

  • Versions with IR LED provide precise object detection at sensing ranges of 2500 mm
  • Immune to ambient light and crosstalk from another sensor, providing reliable operation and less downtime
  • The sensor cover protects configuration components against environmental hazards
  • Adjustable time delay, alarm output, test input, and universal AC/DC voltage provide additional flexibility and reduce the number of part numbers needed
