The Wacker Neuson Oil Alert Sensor is a genuine OEM component designed for VP-series single-direction vibratory plate compactors and BFS-series floor saws, including the VP1135R, VP1135RW, VP1340R, VP1340RW, VP1550R, VP1550RW, VP2050R, VP2050RW, AP1550R, BFS 1345B, BFS 1345BZ, and BFS 1350L. As a direct Wacker Neuson OEM part, is manufactured to the exact specification of the original, ensuring a drop-in fit with no additional adaptation. This sensor plays a critical role in engine protection, and replacing a failed or degraded unit promptly keeps your equipment running safely and efficiently. Verify your machine model and serial number against the fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Engine Protection: — Manufactured by Wacker Neuson to the original sensor specification, delivering accurate low-oil detection rather than an approximation of it.
- Direct-Fit Replacement: — Connects to the existing oil alert circuit using the original wiring harness and mounting point, so installation is straightforward.
- Broad VP and BFS Series Coverage: — Confirmed fitment across VP1135R, VP1340R, VP1550R, VP2050R, AP1550R, and their RW variants, plus BFS 1345B, BFS 1345BZ, and BFS 1350L.
- Engine Shutdown Integrity: — A functioning oil alert sensor triggers automatic engine shutdown before oil pressure drops to a damaging level, protecting the engine block and extending service life.
- Electrical Safety Compliance: — As an OEM safety-critical electrical component, this sensor meets the original circuit resistance and trigger-threshold requirements, ensuring the shutdown system responds correctly under real operating conditions.
The oil alert sensor monitors engine oil level and pressure continuously while the machine is running. When oil drops below a safe threshold, the sensor signals the engine control circuit to shut down the unit automatically, preventing catastrophic internal engine damage. A worn, corroded, or failed sensor can either fail to trigger a shutdown when oil is genuinely low — leaving the engine at risk — or trigger false shutdowns that interrupt work. Replacing the sensor with a genuine OEM part like the Wacker Neuson 5000077425 ensures the protection system works exactly as designed.
