Product Description

Product Overview

This high-precision magnetic pickup speed sensor set (Part Nos. 3078155, 2872353, 4327233, 3073899, 3616371) is specifically engineered for Cummins NT855, NTA855, M11, and NH855 diesel engines—widely utilized in heavy-duty trucks, industrial machinery, and power generation systems. As direct replacements for legacy Cummins part numbers, these sensors deliver ±0.5% speed measurement accuracy and operate reliably in extreme conditions (-55°C to 105°C), ensuring consistent performance in harsh environments.

Constructed with a stainless steel housing and high-temperature epoxy encapsulation, each sensor features a 5/8"-18 UNF-2A threaded interface for secure mounting. The design includes dual-output capabilities to provide redundant signals for engine control modules (ECMs), while the 142 mH inductance guarantees stable output even at low crankshaft speeds (≥100 RPM).

Detailed Product Description 

Advanced Sensing Technology
These sensors utilize a dual-coil magnetic pickup design to detect rotational speed via ferromagnetic gear teeth (with a minimum proximity of 0.028"). The integrated three-stage signal conditioning ensures:

Noise Reduction: Shielded wiring eliminates electromagnetic interference (EMI) from alternators and fuel injectors, ensuring signal integrity.
Thermal Stability: High-temperature epoxy encapsulation prevents signal drift even after 1,000 hours of continuous operation at 105°C.
Redundancy: Dual outputs provide backup signals for ECMs, a critical feature in applications where sensor failure could lead to operational downtime.

Durability & Performance

Vibration Resistance: Tested to withstand 50g acceleration (10-2,000 Hz) without performance degradation, making it suitable for high-vibration environments typical of heavy machinery.
Chemical Compatibility: Resistant to diesel fuel, engine oil, and ethylene glycol-based coolants, ensuring longevity in contact with common engine fluids.
Longevity: Validated to perform reliably for over 10,000 hours in dusty conditions (tested with ISO 12103-A3 fine dust).

Application Scenarios

Heavy-Duty Trucks: Ideal for NT855-powered long-haul trucks, ensuring accurate speed signals for transmission control and engine protection systems.
Industrial Machinery: Compatible with NTA855 engines in construction and mining equipment, providing precise RPM data for load management.
Power Generation: Ensures stable speed control for NT855-driven generator sets (500-1000 kVA) in prime and standby power applications.

Packaging and Delivery

The speed sensors are carefully packaged to prevent any damage during transit. They are typically placed in sturdy cartons with appropriate cushioning materials to protect them from impacts and vibrations. Delivery options can vary, and customers can choose from methods such as express shipping for urgent requirements or more cost - effective sea or land freight for larger orders. The delivery process is coordinated to ensure that the speed sensors each the customers in a timely manner, minimizing any downtime for vehicle maintenance or repair.

Warranty

Cummins offers a warranty on these speed sensors , which provides customers with peace of mind. The exact terms of the warranty may vary depending on the region and the specific application. Generally, the warranty covers any manufacturing defects and ensures that in case of a problem, customers can get the speed sensors epaired or replaced as per the warranty conditions. This warranty reflects Cummins' confidence in the quality of its products.
