BUP-50-HD Elevator Leveling Sensor – IP66 U-Shaped Photoelectric Switch for Accurate Floor Positioning

BUP-50-HD Elevator Leveling Sensor – IP66 U-Shaped Photoelectric Switch for Accurate Floor Positioning


Keep every stop perfectly level. The BUP-50-HD is a heavy-duty, through-beam photoelectric sensor designed for elevator-car positioning. IP66-rated ABS housing shrugs off dust, oil and vibration, while the 50 mm slot and 1 ms response guarantee millimetre-accurate floor alignment.


  • Zero-contact sensing – no mechanical wear
  • 50 mm wide slot accepts opaque targets ≥ Ø 4 mm
  • Light-ON / Dark-ON selectable by wire – one part, two logics
  • IP66 & -25 °C ~ +65 °C working range; survives hoist-way humidity
  • 2 m oil-resistant cable – no extra connector needed
  • CE compliant, 30 mA max. draw – energy-saving & export-ready
