Professional 191-8305 Variable Reluctance High-Speed Sensor for Caterpillar Power Systems
The 191-8305 (1918305) Speed Sensor is a high-performance, Passive Variable Reluctance component engineered for Caterpillar’s most demanding engines and transmissions. Operating independently of an external power supply, this passive unit generates a self-produced AC sine wave signal proportional to rotational speed. Its inherent simplicity makes the 191-8305 an exceptionally reliable choice for monitoring critical engine timing and gear speeds in isolated or high-vibration environments.
I. Reliable Passive Sensing Technology
This sensor utilizes magnetic induction to track passing gear teeth, providing stable high-speed monitoring without the need for complex internal circuitry:
- Over-Mold Construction: Injection-molded nylon is applied directly over the internal magnet and coil, protecting against fluid ingress and high-frequency vibration damage.
- Self-Generated Signal: Produces a clear AC sine wave. As RPMs climb, the sensor maintains signal clarity, providing the ECM with accurate camshaft or transmission data.
- Magnetic Integrity: Features high-grade magnetic pole pieces that maintain flux density even under extreme engine bay temperatures.
II. Extensive Application in Large-Scale CAT Machinery
The 191-8305 is a versatile component found in Caterpillar’s premium power platforms:
| Gas Engines | Essential for G3606, G3608, G3612, and G3616 timing and control. |
| Marine & Petroleum | Trusted for C280-6/12/16 marine engines and C175-16 power units. |
| Mining & Earthmoving | Fits 793 Trucks, AD55 Underground Trucks, and D7R II Tractors. |
| Transmissions | Direct replacement for CX31 Transmissions and C15 truck engines. |
III. Technical Verification & 12-Month Warranty
CRITICAL FITMENT STEP: SIGNAL TYPE VERIFICATION
To ensure your machine returns to work with total confidence:
- Configuration Check: This is a 2-Pin passive unit. Please note it produces an AC Sine Wave, not a digital square wave.
- Expert Double-Check: Send us your Model Number or Engine Serial Number (ESN). Our team will verify compatibility via the CAT database.
- Warranty Protection: Benefit from a full 12-month warranty on this factory-spec, high-speed sensor.
