Cylindrical Photoelectric Sensors BRQ Series

Product Overview

The BRQ Series sensors are Ø18 mm cylindrical photoelectric sensors designed for versatile application in diverse environments. They are available in various configurations, including different sensing orientations (front or side), housing materials (SUS316L stainless steel, nickel-plated brass, or plastic), and body sizes (standard and short-body). These sensors offer a long detection range of up to 30 meters and deliver precise sensing performance. They feature excellent noise immunity and minimal impact from ambient light, making them ideal for environments with challenging lighting conditions. The mutual interference prevention function allows these sensors to be installed in close proximity to each other without performance degradation. With a protection rating of IP67, and an optional IP69K rating for use in high-pressure and high-temperature conditions, these sensors ensure stable and reliable operation even in wet or dusty environments.

Features

• Noise Immunity: Exceptional resistance to electrical noise and ambient light interference.
• Protection Circuits: Includes reverse power, reverse output, and output short overcurrent protection.
• Interference Prevention: Mutual interference prevention allows close installation of multiple sensors (excluding through-beam types).
• Sensitivity Adjustment: Adjustable sensitivity for precise detection and operation.
• Operation Modes: Light ON/Dark ON modes selectable via control wire.
• Material Options: Available in SUS316L stainless steel, nickel-plated brass, and plastic.
• Protection Ratings: IP67 standard, with IP69K models available for high-pressure and high-temperature environments.
