The Autonics BUP-50S U-shaped Photoelectric Sensor uses a through-beam sensing method to detect opaque materials as small as Γ1.5mm at a fixed 50mm range. Powered by a 940nm infrared LED, it delivers stable and accurate detection, even in high-speed automation lines, with a rapid 1ms response time. Engineers can fine-tune performance using the built-in sensitivity adjuster, while the Light ON/Dark ON operation is selectable via control wire for flexible output logic.
Operating on a 12β24VDC supply with Β±10% tolerance, the BUP-50S consumes only 30mA, making it efficient for continuous use. Its NPN open collector output ensures compatibility with a wide range of PLCs and control devices. The robust IP66-rated ABS and polycarbonate housing resists dust, water, and oil, ensuring long-term durability in demanding environments. A 2-meter Γ4mm cable provides secure connectivity, and the included adjuster driver simplifies setup and maintenance. With ambient light resistance up to 11,000lx (sunlight) and an operating temperature range from -25Β°C to 65Β°C, this sensor delivers consistent results in diverse industrial settings.
