The Magnetic MPU 171‑257 is a magnetic pick‑up speed sensor designed for diesel generators and industrial engines. It detects engine or crankshaft rotation by sensing passing ferrous teeth and sends electrical signals to the controller for accurate speed measurement and engine timing. It’s a critical component for proper generator performance and control systems.
Where It Is Used

Diesel generators (commonly Perkins & FG Wilson gensets 7.5 kVA–35 kVA)
-
Industrial engine speed sensing and control systems
-
Applications requiring reliable RPM detection for engine management and safety shutdowns
Key Functions & Features
-
Magnetic pick‑up sensing: Converts rotating gear movement into electrical pulses used for speed monitoring and control.
-
Accurate engine speed detection: Delivers reliable signals for RPM and governor control.
-
Durable construction: Suitable for harsh industrial and genset operating conditions.
-
Easy installation: Standard threaded fit (e.g., M18 × 1.5) for direct replacement.
