Product Description

The Keyence PQ-02 is a compact, amplifier-integrated photoelectric sensor designed for medium-range through-beam detection applications. It features a detection distance of up to 300 mm, making it suitable for detecting small or closely spaced objects. The sensor operates in DARK-ON mode, providing flexibility for various control systems. With a response time of 1 ms and a minimum detectable object size of 0.9 mm (copper wire), it ensures quick and accurate detection. The PQ-02 is housed in a durable enclosure rated IP64, ensuring reliable performance in industrial environments.​
