<p>The BWC cross-beam type area sensors utilize a 3-point
  cross-beam method detection to minimize non-detection area
  and provide reliable detection. 7 different configurations 
  are available based on the number of optical axes, 
  optical pitch, and detection area size. The sensors
  provide reliable detection even in areas with high
  ambient light, up to 100,000 lx. The series also
  features various user-friendly functions including 
  installation mode function, mutual interference 
  prevention function, and self-diagnosis functions.</p>
