RS PRO Retroreflective Photoelectric Sensor Block Sensor 150 mm to 10 m Detection Range PNP Output IP66 IP67 IP69K 729-5157

RS PRO 729-5157 is a retroreflective photoelectric sensor designed as a block sensor for efficient industrial object detection over distances ranging from 150 mm to 10 meters. It features a PNP output type and operates within a 10V to 30V DC voltage range, making it highly compatible with a variety of automation control systems. The sensor is encased in rugged ABS and polymethyl methacrylate material, ensuring durability and resistance against harsh industrial environments.

This sensor incorporates an LED light source emitting visible red light at a wavelength of 640 nm, allowing for consistent and precise detection performance when paired with suitable reflectors. It ensures extremely fast response times of 2.5 milliseconds, which supports rapid object detection essential for high-speed processing lines.

Designed for reliability, the 729-5157 sensor offers IP66, IP67, and IP69K ingress protection standards, making it ideal for wash-down areas, food processing, and environments exposed to dust and moisture. Its operating temperature range from -30 °C to +60 °C extends its application to settings with significant temperature variations.

The sensor includes multiple protection features such as reverse polarity protection, interference suppression, and output over-current/short-circuit protection, enhancing operational stability on industrial power supplies. A 4-pin M12 connector interface facilitates straightforward plug-in installation and integration with PLCs and robotic cells.
