Product Description

The Keyence PZ-G42N is a compact, high-performance photoelectric sensor designed for precise short-range detection in industrial automation applications. Utilizing a red LED light source, it offers a detection range of up to 300 mm, making it suitable for applications requiring close-range sensing. The sensor features a built-in amplifier, simplifying installation and reducing wiring complexity. With a rectangular shape and a 2-meter cable connection, it provides flexibility in various setups. The PZ-G42N supports both LIGHT-ON and DARK-ON operation modes, selectable via a switch, and includes a 1-turn sensitivity adjustment trimmer for fine-tuning. Its robust design ensures reliable performance in harsh environments, with an enclosure rating of IP67/NEMA 4A, 6, 12, and IP69K, making it suitable for applications exposed to dust, water, and high-pressure washdowns.
