Product Description

The Keyence PR-FB30N3 is a compact, self-contained photoelectric sensor designed for precise background suppression applications. Its flat, reflective design allows for detection distances ranging from 1 to 30 mm, making it ideal for detecting small or closely spaced objects. The sensor offers both Light-ON and Dark-ON output modes, providing flexibility for various control systems. With a response time of 0.5 ms and a spot diameter of approximately 5 mm at 30 mm detection distance, it ensures quick and accurate detection. The PR-FB30N3 is housed in a durable SUS316L stainless steel casing and is rated IP67, IP69K, and NEMA 4X, 6P, 13, ensuring reliable performance in harsh industrial environments.
