The Keyence PZ-G41CN Square Reflective Sensor is a compact, high-performance photoelectric sensor designed for industrial applications that demand long-range detection and durability. Featuring a rectangular housing with M8 connector type output, this model is optimized for reliable operation in automation systems where both flexibility and resilience are critical.

This sensor’s standout capability is its diffuse reflective detection range of up to 1 meter when detecting standard white paper targets measuring 30 × 30 cm. This extended detection distance enables the PZ-G41CN to handle a wide variety of objects, including larger surfaces and materials placed at greater distances from the sensor. The red LED light source ensures clear, stable detection performance with consistent output feedback.

With a response time of 500 µs, the PZ-G41CN is well-suited for high-speed operations, ensuring quick and accurate detection of moving or fast-passing objects. Its LIGHT-ON/DARK-ON switch-selectable operation provides flexibility for diverse system requirements, while built-in output and stability LEDs (orange and green, respectively) give operators instant visual confirmation of sensor status during operation.

Ease of setup is another key advantage. The unit features a 1-turn sensitivity trimmer (230°), making it simple to fine-tune detection according to application needs. Combined with its M8 connector interface, the sensor allows quick connection, replacement, or maintenance, reducing downtime and simplifying integration into existing industrial systems.

Engineered for rugged performance, the PZ-G41CN is built to withstand demanding operating environments. Its glass-fiber reinforced PBT housing, polyarylate lens cover, and robust internal components ensure structural integrity, while its IP67/IP69K enclosure rating guarantees protection against dust, water spray, and even high-pressure washdowns. It also meets NEMA standards (4A, 6, 12), further proving its suitability for challenging industrial environments such as food processing, packaging, and outdoor installations.

The sensor is highly resistant to external interference, thanks to its automatic different frequency function, which allows up to two units to operate without signal overlap. Electrical protection is also integrated, including reverse polarity protection, overcurrent protection, and surge absorption, safeguarding both the device and connected equipment.

Environmental adaptability is ensured with a wide operating range of -20 to +55 °C and tolerance to ambient light up to 20,000 lux sunlight and 5,000 lux incandescent light, enabling reliable detection even in brightly illuminated or variable lighting conditions. It is also designed to withstand vibration (10–55 Hz, 2 hours in all axes) and shock resistance of 1,000 m/s² applied six times per axis, making it a dependable choice for heavy-duty environments.

Weighing just 10 g, the PZ-G41CN is lightweight yet built with industrial-strength materials, ensuring both portability and long-term durability. Its combination of long-range detection, rugged environmental resistance, and ease of setup makes it ideal for diverse industrial applications such as packaging lines, assembly processes, materials handling, and quality inspection systems.
