The Autonics BF4G-R offers fast, stable detection performance with its External Input Sensitivity Setting type and Green LED (525nm) light source. It features a rapid response time of 0.5ms (Frequency 1) and 0.7ms (Frequency 2), ideal for high-speed part counting, edge detection, and transparent object identification. Powered by 12β24VDC Β±10%, this sensor maintains stable operation with low current consumption of max. 45mA. The amplifier allows engineers to switch between Light ON / Dark ON modes easily via the ON/OFF button, and its NPN open collector control output integrates well into existing industrial control systems.
The BF4G-R includes a practical OFF Delay (40ms) function to help filter unwanted signal noise, improving detection accuracy. It also features self-diagnosis output for error states like unstable sensing or output short-circuitingβgiving real-time feedback for preventive maintenance. Built with heat-resistant ABS housing and polycarbonate cover, the sensor can operate in ambient conditions from -10Β°C to 50Β°C and humidity up to 85% RH. With a compact 6-wire design and included mounting accessories, installation is fast and reliable.
