Specification

SEODescription

The Q38DB Photoelectric Sensor and Q38DB Inductive Switch are versatile industrial sensors designed for precise object detection. The Q38DB 30mm NPN Sensor variant features a compact housing with a 30mm sensing range, utilizing photoelectric technology for reliable detection of transparent or opaque objects, while the inductive version detects metallic targets. Both models operate on a 10-30V DC supply, support NPN output configurations, and integrate seamlessly with PLCs or control modules via direct wiring. They operate efficiently in temperatures ranging from -25°C to 70°C, making them ideal for harsh environments in automotive, packaging, and material handling industries. Key advantages include high durability, resistance to environmental interference, and easy installation. However, the inductive variant is limited to metallic objects, and the photoelectric sensor may require calibration for specific surface reflectivity. Both versions lack built-in communication protocols but excel in straightforward industrial automation tasks.
