SA1U Photoelectric Switches

Universal voltage and DC power types available.


  • Universal voltage types operate on 24 to 240V AC and 12 to 240V DC. DC power types operate on 12 to 24V DC.
  • Washable IP67
  • Four sensing methods: through-beam, polarized retroreflective, diffuse-reflective, and background suppression.
  • Adjustable time delay: 0.1 to 5 seconds
  • Mounting hole centers: 40, 50 to 55 mm
  • Operation and stable LED indicators.
  • SPDT contact for relay output type.
  • Transistor output type has NPN and PNP open collector dual outputs.
  • Interference prevention allows two units to be mounted in close proximity (except through-beam type).
  • Spring-up terminal block structure enables easy wiring. Wiring can be extended to up to 100m using ø8 to ø10 mm round cables.
