Autonics FD-420-05 Fiber Optic Sensor
Autonics FD-420-05 Diffuse Reflective Fiber Optic Sensor Unit
Autonics FD-420-05 is a diffuse reflective fiber optic sensing unit with 2 m of FREE-CUT plastic fiber, engineered for reliable small-object detection in compact and harsh industrial environments when paired with Autonics fiber amplifiers.
The Autonics FD-420-05 is a diffuse reflective type fiber optic sensor unit from the FD/GD Series, designed for accurate detection of small objects in tight installation spaces, high-vibration areas, and electrically noisy environments.
It features a 2 m FREE-CUT plastic fiber cable, allowing on-site length adjustment using a compatible cutter. The FD-420-05 must be used with an Autonics fiber optic amplifier (BF3RX, BF4R, BF5R series, etc.) to form a complete sensing system.
