【English Introduction】
The Pepperl+Fuchs NBB4-12GM50-E0 and NBB4-F1-E2 proximity switches are non-contact detection devices developed with mature technology, specifically designed for industrial automation applications. Featuring a compact cylindrical housing (12mm diameter), these inductive sensors reliably detect metal targets through electromagnetic principles, simplifying mechanical installation and enhancing system integration.
The NBB4-12GM50-E0 model offers a 12mm sensing range with M12 connector interface, utilizing DC 2-wire connection. Its stainless steel housing provides exceptional mechanical durability, capable of withstanding vibrations up to 10g (10-55Hz frequency range). Operating within -25℃ to +70℃ temperature range and IP67 protection rating, it demonstrates reliable performance in environments with oil, dust, or temporary water immersion.
The NBB4-F1-E2 variant maintains core series advantages while optimizing output characteristics. This DC 3-wire model features switchable NO/NC contacts to accommodate different control systems. The built-in status indicator facilitates on-site commissioning, with 1kHz response frequency suitable for high-speed object detection.
Both models undergo rigorous factory testing with industrial-grade EMC performance. The fully sealed, non-moving-part design ensures extended service life exceeding 100,000 MTBF. Supporting flush or non-flush mounting, these sensors find applications in machinery manufacturing, automotive production lines, packaging equipment, and logistics sorting systems, delivering stable detection for equipment safety.
