Autonics BFX-D1-N Digital Fiber Optic Amplifiers

The Autonics BFX-D1-N is a high-speed, dual-display digital fiber optic amplifier engineered for high-precision sensing applications. It mounts onto standard 35 mm DIN rails and pairs with Autonics plastic fiber optic cables (FT/FD series) to detect tiny components, marks, or edges in tight industrial environments.

Key Features & Operating Benefits

• High-Contrast LCD Dual Display: Displays the current light intensity (PV) and the active threshold limit (SV) simultaneously for clear visibility.

• Ultra-Fast 50 µs Speed Mode: Capable of detecting rapidly moving targets on high-speed conveyor lines or indexing stations.

• Anti-Saturation Function: Automatically dampens light emission intensity when targets are very close to prevent signal overflow/saturation.

• External Input Terminal: Supports remote teaching, emitter OFF control, peak reset, and power-saving modes via external control lines.

Typical Applications

• High-Speed Packaging: Print registration mark detection and clear bottle/cap presence verification.

• Semiconductor & Electronics: Pin alignment, IC chip positioning, and PCB edge detection inside robotic pick-and-place machines.

• Pharmaceutical Machinery: Blister pack inspection, tablet counting, and liquid fill level checking.
