The Wacker Neuson is a genuine OEM Pressure Switch designed for the RD27-100 and RD27-120 hydrostatic vibratory rollers. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component installed at the factory. It is confirmed compatible across multiple configurations of the RD27-100 and RD27-120 series, giving you confidence that you are ordering the correct part for your machine. Replacing a faulty or failed pressure switch with a genuine Wacker Neuson part restores proper hydraulic system monitoring and keeps your roller operating as intended.
Key Features
- Genuine OEM Pressure Rating: — Matched to the exact switching threshold required by the RD27 hydraulic circuit — no calibration guesswork or aftermarket variance.
- Direct Connector Compatibility: — Plugs into the existing wiring harness and hydraulic port on the RD27-100 and RD27-120 without modification, using the original mounting configuration.
- Confirmed RD27 Series Fitment: — Verified for RD27-100 and RD27-120 hydrostatic vibratory rollers across all listed machine configurations.
- Hydraulic System Integrity: — A correctly functioning pressure switch ensures the machine's hydraulic circuit is continuously monitored, triggering protective shutdowns or alerts before low-pressure conditions cause pump or drive damage.
- Electrical Safety Compliance: — As a genuine OEM electrical sensing component, the 5000161531 meets Wacker Neuson's original circuit protection requirements, reducing the risk of undetected hydraulic faults during operation.
A pressure switch monitors fluid pressure within the hydraulic system and sends an electrical signal when pressure drops below or exceeds a set threshold. On tandem rollers like the RD27 series, this is critical for protecting the hydrostatic drive system — if hydraulic pressure falls outside the safe operating range, the switch triggers a warning or shutdown to prevent serious component damage. When a pressure switch fails, the machine may operate without pressure protection, run erratically, or display fault codes that prevent normal operation.
