Product Description

The Keyence PZ-M33P is a compact, high-performance photoelectric sensor designed for precise object detection in industrial automation applications. This multi-reflective sensor features a 5 to 300 mm detection range, red LED light source, and a 1-turn sensitivity adjustment trimmer for easy calibration. It offers a fast response time of up to 1 millisecond and supports both LIGHT-ON and DARK-ON operation modes. The sensor is equipped with PNP output, providing a control output of up to 100 mA at 24 V with a maximum residual voltage of 1 V. Its robust construction includes a glass-fiber reinforced plastic housing with an IP67 enclosure rating, ensuring reliable performance in harsh environments. The PZ-M33P operates within a wide temperature range of -20°C to +55°C and is resistant to ambient light up to 20,000 lux, making it suitable for various industrial settings.​
