Balluff BES-515-449-SA7-S21 Inductive Proximity Switch

The Balluff BES02FP (BES 515-449-SA7-S21) is a cylindrical inductive proximity switch designed for flush-mount installation in industrial automation. It has an Ø12 mm, 70 mm-long M12x1 housing, and a 2 mm sensing distance, making it suitable for compact spaces. The sensor provides a normally open (NO) switching output, enabling straightforward integration into control circuits for metal-detection tasks. As part of Balluff’s BES proximity sensor family, the BES02FP is built for reliable operation in industrial environments and supports flush-mount installation to minimize profile within equipment. This variant, identified by 515-449-SA7-S21, combines a small footprint with a short detection range for detecting metal proximity in automation lines, conveyors, and machine assemblies where space is limited.
