Designed for real-time signal processing, the Autonics BF4R-E is a precision Fiber Optic Sensor Amplifier that features an external synchronization input and a reliable Red LED (660nm) light source. With selectable response times of 0.5ms (Frequency 1) and 0.7ms (Frequency 2), this amplifier enables high-speed object detection in automated production lines. It operates on 12–24VDC power with a ripple tolerance of ±10% and consumes only max. 45mA, ensuring energy-efficient, consistent performance across dynamic environments. Sensitivity is adjusted manually, and Light ON/Dark ON modes can be set using the front panel ON/OFF button. The NPN open collector output allows easy integration into PLCs and control systems.
The BF4R-E comes with advanced self-diagnosis output that triggers alerts under unstable sensing or short-circuit conditions, helping prevent unexpected downtime. Its robust housing—made from heat-resistant ABS and polycarbonate—ensures durability in temperatures ranging from -10°C to 50°C and relative humidity up to 85%. This model includes built-in stop transmission and external sync (gate/trigger) functions, enhancing coordination in multi-sensor setups. With a compact 6-wire design and supplied mounting accessories, the BF4R-E is engineered for straightforward installation in tight control panels.
