Product Description

The KEYENCE PZ2-51 is a compact, high-performance photoelectric sensor designed for precise object detection in industrial automation applications. Utilizing a thrubeam detection method, it offers a detection distance of up to 7 meters, making it suitable for various material handling and positioning tasks. The sensor features a red LED light source and is capable of detecting opaque objects with a minimum area of 30 mm². Its built-in amplifier design ensures a streamlined setup, reducing the need for external components. With an IP67-rated enclosure, the PZ2-51 is resistant to dust and water ingress, ensuring reliable operation in harsh environments. The sensor's 1-turn trimmer sensitivity adjustment allows for fine-tuning, while its 1.5 ms maximum response time ensures quick detection. The PZ2-51 is ideal for applications requiring precise, long-distance detection in compact spaces.
