Photoelectric Sensors for PCB Detection The BJP series photoelectric sensors are optimized for detection of printed circuit boards (PCB) with a 30 mm x 3 mm rectangular light beam and background suppression (BGS) sensing method. The sensors provide accurate and stable detection of PCBs regardless of holes, protrusions or intrusions on the boards. Configuration is made simple with operation mode switch and adjustable sensing distances. Main features 30 mm x 3 mm light beam (at 30 mm distance) provides accurate detection of PCBs regardless of holes, protrusions, intrusions, or errors on the boards. Background suppression (BGS) sensing method allows stable detection regardless of the color, texture or surface of the background object. Sensing distance: 10 to 100 mm (adjustable distance: 20 to 100 mm) Light ON / Dark ON operation mode switch Built-in reverse polarity protection circuit and output overcurrent (short-circuit) protection circuit IP65 protection structure (IEC standard)
