The Autonica BF5R-D1-P is a dual-display standard-type sensor featuring a 4-digit 7-segment LED readout and a red LED light source at 660 nm. It offers precise response times of 50 μs, 150 μs, 500 μs, 4 ms, and 10 ms to cover a range of sensing applications, and operates from 12 to 24 V DC with a ripple tolerance of up to 10%. The device draws a maximum of 50 mA and supports Light ON or Dark ON operation set by a parameter, with a PNP open-collector control output and a versatile timer function including OFF, OFF Delay, ON Delay, and One-shot (1 to 5000 ms). Sensitivity is adjustable manually and supports teaching options such as auto-tuning, 1-point, 2-point, positioning, with batch teaching available when multiple units are connected via I2C for up to eight units. It tolerates ambient illumination up to 11,000 lx in sunlight and 3,000 lx under incandescent lighting, and operates from -10 to 50°C (storage -20 to 70°C) with IP40 protection and 35–85% RH humidity (storage). The unit features built-in mutual interference prevention, initializes in factory mode, and offers energy-saving modes (Normal, Energy Saving 1, Energy Saving 2). The housing uses a polybutylene terephthalate case with a polycarbonate cover, and the cable is Ø4 mm, 3-wire, 2 m long with AWG22 conductors plus a side connector for easy installation. Accessories include a fixing bracket, bolts, and nuts.
