The Dr.E.Horn FRG00035-R-138 is a high-performance differential Hall-effect speed sensor designed for precise and reliable measurement of rotational speed. Engineered for demanding industrial and marine applications, this sensor operates without contact, detecting the movement of ferromagnetic targets like gear wheels. Its robust stainless steel housing and IP68 protection rating ensure durability and consistent performance even in harsh environments with high temperatures, vibration, and moisture. The sensor provides a clean, square-wave output signal, making it compatible with a wide range of control systems, tachometers, and monitoring equipment.
