Photoelectric sensors use a beam of light to detect objects without touching them, often from several meters away. They are a staple of packaging, material handling and assembly lines, counting cartons, checking for missing parts and confirming that a product is in position.

Sensing Modes

• Through-beam – separate emitter and receiver for the longest range and highest reliability
• Retroreflective – a single sensor and reflector, easy to align across conveyors
• Polarized retroreflective – detects shiny and wrapped objects without false triggers
• Diffuse and background suppression – sense the target directly and ignore what's behind it
• Clear object and contrast sensors – for bottles, film and printed marks

Selecting the Right Sensor

Consider range, target size, color and surface, and whether there's room for a reflector or receiver. Laser and red-light versions make alignment easier, and IO-Link models allow remote setup and diagnostics. For washdown areas, look for stainless housings rated IP67 or IP69K.
