Brief: Get a guided demo that shows common workflows and troubleshooting tips for the BUP-50-HD Elevator Leveling Sensor. In this video, you'll see how this U-shaped photoelectric switch ensures millimetre-accurate floor positioning for elevator cars, demonstrating its robust IP66-rated housing and zero-contact sensing technology in action.
Related Product Features:
  • Zero-contact through-beam sensing eliminates mechanical wear for long-term reliability.
  • Features a 50 mm wide U-slot capable of detecting opaque targets as small as Ø 4 mm.
  • Light-ON or Dark-ON output logic is selectable via wiring for flexible integration.
  • IP66-rated ABS housing provides robust protection against dust, oil, and water ingress.
  • Operates reliably across a wide temperature range from -25 °C to +65 °C.
  • Includes a 2-meter oil-resistant pig-tail cable, eliminating the need for an external connector.
  • Fast response time of ≤ 1 ms ensures precise and timely elevator car positioning.
  • CE compliant with a low current consumption of ≤ 30 mA for energy-efficient operation.
Faqs:
  • What is the sensing principle of the BUP-50-HD sensor?
    The BUP-50-HD uses a through-beam (U-slot) photoelectric sensing principle. An infrared LED emitter and receiver are housed opposite each other in the U-shaped slot, detecting when an object interrupts the beam, enabling zero-contact and wear-free operation.
  • How is the output mode configured?
    The output mode is selectable between Light-ON and Dark-ON logic via the wiring configuration. This allows you to choose the desired output state (ON when the beam is uninterrupted or ON when it is blocked) without needing different sensor models, offering great installation flexibility.
  • What environmental conditions can this sensor withstand?
    With an IP66 protection rating, the sensor is sealed against dust and powerful water jets. It operates in temperatures from -25 °C to +65 °C and is built to endure the humidity and vibrations typical in elevator hoist-ways, ensuring reliable performance in harsh conditions.
  • What is the minimum object size this sensor can detect?
    The sensor can reliably detect opaque objects with a diameter of 4 mm or larger that pass through its 50 mm wide U-slot, providing the precision needed for accurate elevator floor leveling.
