General Purpose Area Sensors BW Series

Product Overview

The BW series general-purpose area sensors are designed to provide reliable and accurate sensing capabilities across various applications. These sensors offer a long sensing distance of up to 7 meters and come in 22 configurations, tailored according to the number of optics, optical pitch, and detection area size. With an ambient illuminance limit of 100,000 lux, these sensors can perform flawlessly even in challenging environments, such as under direct sunlight. The inclusion of bright LED indicators on both the emitter and receiver ensures that the operation status is always clearly visible. Additionally, the sensors support mutual interference prevention through a master/slave connection, enabling multiple units to be seamlessly installed side by side.
