The Autonics BF3RX-P is a fiber optic amplifier sensor equipped with a PNP open-collector output, designed for accurate and stable object detection when paired with compatible Autonics fiber optic units. It uses a red LED light source (660 nm, modulated) and provides reliable sensing even in dusty, narrow, or high-temperature areas where conventional photoelectric sensors cannot be installed.
The amplifier supports Light ON / Dark ON selection via control wire and offers coarse and fine sensitivity adjustment for precise tuning.
