The Keyence PZ-G42CP is a high-performance diffuse reflective photoelectric sensor designed for industrial automation applications that demand reliability, precision, and durability. Engineered in a compact rectangular housing, this sensor provides powerful detection capabilities while maintaining a space-saving profile. Equipped with a standard M8 connector, the PZ-G42CP ensures straightforward installation, secure connections, and compatibility with a wide range of system setups.

At the core of its functionality is its diffuse reflective sensing method, enabling the sensor to detect objects within a range of up to 300 mm. When aimed at a standard 10 x 10 cm white paper target, it delivers consistent and repeatable results, making it a dependable choice for applications involving part presence, object counting, or position sensing. Its short-range reflective design is well-suited for scenarios where background suppression is unnecessary, providing both simplicity and cost-effectiveness.

The PZ-G42CP outputs a PNP open-collector signal, ensuring smooth integration into modern control systems. Its fast 500 µs response time allows it to track rapid object movements without delay, a critical feature for high-speed production lines. In addition, the sensor includes selectable operation modes, allowing users to choose between light-on and dark-on operation to fit different detection requirements.

Durability is a defining trait of the PZ-G42CP. Built with a fiber-reinforced PBT resin housing and a polyarylate lens cover, it offers resistance against wear, moisture, and harsh cleaning processes. Its IP67/IP69K-rated enclosure and compliance with NEMA standards make it suitable for environments exposed to dust, water spray, or washdown conditions. Vibration and shock resistance ensure dependable operation even in demanding mechanical environments.

The sensor is also engineered with built-in protection circuits, including reverse polarity, overcurrent, and surge absorption, providing long-term reliability and minimizing the risk of system failures. LED indicators simplify setup and operation by offering clear visual feedback on output status and detection stability.

Compact, rugged, and reliable, the Keyence PZ-G42CP offers a balance of high-performance sensing and practical installation features. It is an excellent solution for manufacturers seeking to optimize automation systems with a short-range, diffuse reflective sensor that maintains stability under demanding operating conditions. Whether deployed in packaging, assembly, or general factory automation, this sensor delivers consistent performance and long-lasting durability.
