Series Information

BRQ Series

Cylindrical Photoelectric Sensors

The Autonics BRQ series Ø18 mm cylindrical photoelectric sensors are available in various sensing sides (front, side), housing material (SUS316L stainless steel, nickel-plated brass metal, plastic), and body sizes (standard, short-body) for flexible application in diverse environments. The sensors feature long detection distance up to 30 m and accurate sensing performance with excellent noise immunity and minimal influence from ambient light. Mutual interference prevention function also allows the sensors to be installed close together. With IP67 protection rating, the sensors offer stable and error-free operation even in wet or dusty environments. The IP67K models are also available for application in high pressure and high temperature water and dust environments.
