Photoelectric sensors
Photoelectric sensors are optoelectronic devices designed for non-contact detection of objects, utilizing light beams (typically infrared, visible red, or laser) to sense presence, position, or distance.

Photoelectric sensors are optoelectronic devices designed for non-contact detection of objects, utilizing light beams (typically infrared, visible red, or laser) to sense presence, position, or distance. These sensors operate in through-beam, retro-reflective, or diffuse modes, with sensing ranges from a few millimeters up to 60 meters depending on the model. Key technical parameters include supply voltage (typically 10-30 VDC), output types (PNP, NPN, or analog), response time (often under 1 ms), and housing materials (stainless steel or plastic with IP67 or IP69K protection). They are essential for precise detection in industrial automation, offering immunity to electromagnetic interference and reliable performance in dusty or wet environments.
These sensors are widely deployed in manufacturing, packaging, logistics, and material handling sectors. Common applications include presence detection on conveyor belts, object counting, positioning in assembly lines, and level monitoring in automated storage systems. They are also used in the automotive industry for part verification, in food and beverage processing for hygienic sensing, and in printing or labeling machines for edge detection. Their ability to detect transparent, shiny, or small objects makes them versatile for complex automation tasks.
Subcategories include through-beam sensors (emitter and receiver pair), retro-reflective sensors (with reflector), and diffuse sensors (with background suppression or foreground suppression). Key article codes often follow a pattern like E3Z, E3F, or E3JK series from major manufacturers, with suffixes indicating sensing mode (e.g., -D for diffuse, -R for retro-reflective) and output type (e.g., -N for NPN, -P for PNP). For example, the E3Z-D61 model is a diffuse sensor with a 1-meter range and PNP output. Other common series include the E3FA, E3FB, and E3S-AD series, each tailored for specific sensing distances and environmental conditions.
