Description
Long Description
The 3034572 Magnetic Pickup Sensor is designed for industrial diesel engines and generator sets (such as Cummins K38, QSK38, KTA38, G38, and similar models). It’s a critical component in speed governors and engine control systems.
-
Threaded specs: 5/8‑18 UNF‑2A, 120 mm length
-
Operating Principle: Generates an AC output (~1.5 VAC at cranking, up to 30 VAC at speed) as gear teeth pass the sensor tip
-
Electrical Specs: Coil resistance max 300 Ω
-
Temperature Range: –55 °C to +105 °C
-
Installation Clearance: Requires 0.028–0.042 in. gap between sensor tip and gear teeth
-
Housing: Durable metal body for long-term rugged operation
This sensor is ideal for reliable speed sensing on large diesel gensets and heavy-duty equipment, built to resist high vibration, heat, and environmental exposure.
