Product Details
Professional 201-6616 High-Coil Speed Sensor for Caterpillar Engines & Transmissions
The 201-6616 (2016616) Variable Reluctance Speed Sensor is a critical electronic component designed to capture the high-frequency rotational data required by your Caterpillar machine’s ECM. Utilizing a specialized “High-Coil” design, this sensor converts the mechanical movement of gears into a precise AC sine wave signal. Whether synchronizing camshaft timing or monitoring transmission output on a CX31 gearbox, the 201-6616 ensures your machine operates with factory-spec precision.
I. High-Coil Technology: Engineered for Reliability
The 201-6616 stands out due to its high-output coil architecture, which provides superior sensing capabilities through magnetic induction:
- Passive Operation: A “self-powered” sensor that generates its own voltage. This eliminates the need for external power wires, significantly reducing the risk of electrical shorts.
- Superior Signal Clarity: High-coil density ensures a strong, clear signal even at lower cranking speeds—vital for starting large engines in D10T and D11T dozers.
- Reinforced Plastic Housing: Formulated for high-vibration and high-temperature environments, resisting chemical degradation from engine oils and hydraulic fluids.
II. Wide-Ranging Application Across the CAT Lineup
The 201-6616 is one of the most versatile speed sensors in the Caterpillar inventory:
| Mining & Dozers | Primary sensor for D10N/R/T, D11T, and 854K wheel dozers. |
| Excavators & Loaders | Optimized for 345C/D L and 966H, 972H, 990H, 992K loaders. |
| Articulated Trucks | Essential for 725, 730, and 773F off-road series. |
| Industrial & Graders | Fits 14M/16M Motor Graders and SR4/B/5 Generators. |
III. Technical Verification & 12-Month Warranty
CRITICAL FITMENT STEP: PASSIVE VS. ACTIVE CHECK
Caterpillar utilizes multiple speed sensor configurations. To ensure a perfect fit:
- Identification: This is a Plastic Variable Reluctance (Passive) sensor. Confirm your existing unit is not an “Active” (hall-effect) type.
- Expert Support: Send us your Machine Model or Engine Serial Number (ESN). Our team will verify the fitment against the official CAT database.
- Warranty: Benefit from a full 12-month warranty on this factory-new, rigorously tested component.
