The SA1E-BP1 is a miniature high performance photoelectric sensor featuring background suppression sensing compatible with different colour objects. The sensor features a 1ms maximum response time, allowing continuous detection of closely spaced objects. The sensor features an easy-to-allign optical axis and visible red LED allowing the detecting position to be seen. Brackground suppression ignores the background and detects the objects only, making it suitable for detecting small objects with narrows gaps on PCB lines.
