Balluff
Balluff is a German sensor and automation technology manufacturer founded in 1921 and headquartered in Neuhausen auf den Fildern, Germany, operating as a family-owned company with global sales subsidiaries and manufacturing across Europe, the Americas, and Asia. The company’s magnetic sensor portfolio centers on its magnetic cylinder sensors — a product line for which Balluff is particularly well known, offering piston position detection directly on pneumatic and hydraulic cylinders using embedded permanent magnet targets — alongside a broad range of proximity sensors, linear position transducers (LPTs and BTLs using magnetostrictive technology), Hall effect switches, and RFID systems. Balluff’s linear position transducer (BTL series) based on magnetostrictive technology is widely specified in machine tools, hydraulics, and automation where absolute, non-contact multi-position measurement over long strokes is required, and the company rounds out its magnetics-adjacent portfolio with magnetic field indicator accessories and mounting hardware for its cylinder sensor line.
