Autonics BUP-50-P operates on a through-beam sensing method with a 50mm detection range, capable of sensing opaque objects as small as Γ4mm. It uses a high-performance 940nm infrared LED with a rapid 1ms response, making it highly efficient for conveyor and high-speed automation applications. Powered by a 12β24VDC supply and consuming just 30mA, this P Sensor ensures energy efficiency and stable output via a PNP open collector. Built with an IP66-rated ABS and polycarbonate body, it resists dust, oil, and water, ensuring durability in demanding environments. Its robust Γ4, 2m cable connection provides reliable installation in compact or vibration-prone machinery. With selectable Light ON/Dark ON modes and fixed sensitivity, the BUP-50-P integrates seamlessly with PLCs and automation controllers for reliable detection tasks.
The Autonics BUP-50-P is widely used for component verification, position sensing, and small-part detection in assembly lines, packaging, and electronics manufacturing. Maintenance engineers prefer its low-maintenance design, while automation students benefit from hands-on learning with a practical U-shaped Photoelectric Sensor. Its compact slot design makes it ideal for areas where cylindrical sensors cannot fit, providing precise, consistent detection in modern factory automation. With speed, reliability, and durability, the BUP-50-P remains a trusted choice for industrial automation teams.
The BUP-50-P, often referred to as BUP or Autonics BUP-50-P, is part of the proven Autonics sensor range designed for demanding automation needs. Buyers value this P Sensor for its stable performance, rugged IP66 protection, and integration flexibility. Recognized for accuracy and dependability, the Autonics BUP helps industries achieve consistent detection across multiple applications.
