Wacker Neuson 5200007992 Air Filter Restriction Sensor

The Wacker Neuson is a genuine OEM Air Filter Restriction Sensor designed for the RD27-100 and RD27-120 series tandem rollers. As a factory-original component, the is manufactured to the same specifications as the sensor installed at the factory, ensuring accurate detection and seamless integration with the machine's monitoring system. This sensor fits across a wide range of RD27 configurations, including the RD27 Pro Tandem Roller, RD27-100 Roller Pro T4F, RD27-120 Roller Pro T4F, RD27-100 Roller Basic T4F, and RD27-120 Roller Basic T4F. Choosing the correct OEM part number is the most reliable way to confirm compatibility and maintain machine performance on the job.

Key Features

• Accurate Restriction Detection: — Calibrated to the precise pressure-differential threshold of the RD27 series air intake system, ensuring the sensor triggers at the correct restriction level — not too early, not too late.
• Genuine OEM Part: — Sourced directly from Wacker Neuson, this sensor matches the original component specification for the RD27-100 and RD27-120, with no guesswork on fit or connector compatibility.
• Broad RD27 Series Coverage: — Compatible with multiple RD27 machine numbers across the RD27-100 and RD27-120 families, including Pro and Basic T4F configurations and earlier hydrostatic vibratory roller variants.
• Protects Engine Health: — A functioning air filter restriction sensor alerts the operator before a clogged filter starves the engine of clean air, helping prevent accelerated wear and unplanned engine service.
• Direct Plug-In Replacement: — Connects to the existing wiring harness on supported RD27 models, allowing straightforward swap-out during routine filter service or sensor failure diagnosis.

The air filter restriction sensor monitors the pressure differential across the engine air filter to detect when the filter becomes excessively clogged or restricted. When the filter reaches the point where airflow is significantly reduced, the sensor triggers a warning signal, alerting the operator to service or replace the filter before engine performance is affected. A failed or inaccurate restriction sensor can either miss a real restriction — leaving the engine running with starved airflow — or generate false alerts that disrupt normal operation; replacing a suspect sensor with a genuine OEM part like the Wacker Neuson 5200007992 restores confidence in the machine's monitoring system.
