The Autonics BF4R-R is engineered as a Fiber Optic Sensor Amplifier with external input sensitivity setting capability via SW1 and SW2, providing flexible detection control directly from external switches. It uses a Red LED (660nm) light source and delivers quick signal processing with a response time of 0.5ms (Frequency 1) and 0.7ms (Frequency 2). The amplifier operates on a standard 12β24VDC Β±10% supply and consumes just max. 45mA, ensuring stable performance with low power draw. Engineers can toggle Light ON/Dark ON operation using the built-in ON/OFF button, and the NPN open collector output supports seamless integration into PLC-controlled environments.
The BF4R-R includes a self-diagnosis output that alerts users to unstable sensing or output short circuits, helping prevent costly equipment failures. An OFF Delay timer (40ms) is also included to reduce signal noise and false detections. With a 6-wire cable design and compact construction, this amplifier is easy to install inside tight control panels. The housing is built with heat-resistant ABS and polycarbonate, allowing it to withstand ambient temperatures from -10Β°C to 50Β°C and humidity up to 85% RH. It comes complete with fixing brackets and mounting hardware. To compatible models, visit the Autonics Sensors & Controllers brand page or see the full selection at Autonics Fiber Optic Sensors.
This model is well-suited for use in electronic assembly lines, packaging machines, food processing equipment, and pick-and-place systems where quick feedback and consistent signal output are critical. The Autonics BF4R-R delivers consistent sensing even in challenging conditions, making it a preferred choice for OEMs, machine builders, and automation maintenance engineers across India.
