Wheel Probe

The MONIT Wheel Probe (PR001) is an inductive speed sensor engineered for wheel hub mounting applications where accurate rotational velocity data is critical. This steel-constructed probe delivers reliable wheel speed detection through electromagnetic induction, eliminating mechanical contact wear and providing consistent signal output across a wide range of operating conditions. The zinc oxide protective coating ensures corrosion resistance in harsh automotive environments, making it suitable for both OEM replacements and performance measurement systems.

Inductive wheel probes function by detecting ferrous material movement—typically tone rings or ABS reluctor rings mounted on wheel hubs. As the wheel rotates, the probe generates proportional voltage pulses that translate to precise speed calculations. The compact 3.5 x 1.5 x 5.5 inch form factor and lightweight 0.22 lb construction allow straightforward installation in confined hub spaces without adding significant mass. Steel construction provides mechanical durability while withstanding vibration, thermal cycling, and the mechanical stresses inherent to wheel-speed measurement in vehicle dynamics applications.

This sensor is essential for technicians upgrading ABS systems, implementing traction control retrofits, or installing performance data acquisition systems that require independent wheel-speed inputs. Motorsport applications, off-road diagnostics, and precision braking system tuning all depend on the accuracy and stability that inductive sensing provides. The wheel probe eliminates common problems associated with mechanical switches—chattering, contact resistance drift, and debris sensitivity—delivering the signal integrity needed for modern vehicle control systems and telemetry equipment.

Compatible with any system designed to accept standard inductive wheel speed sensors, the MONIT PR001 serves as a direct replacement for OEM units or as an original component in custom ABS and traction control builds. The zinc oxide finish resists salt spray, moisture, and road contamination—critical for longevity in marine, coastal, and winter environments. Buyers should verify tone ring compatibility and signal cable specifications before installation to ensure proper integration with existing control modules or data acquisition hardware.

TacticalSurplusUSA stocks the MONIT Wheel Probe as a single unit for customers requiring reliable OEM-grade speed sensing without bulk purchasing. Whether you're rebuilding a classic ABS system, upgrading suspension diagnostics, or assembling a data acquisition platform, this inductive sensor delivers the precision and durability automotive technicians depend on.
