The Wacker Neuson Magnet is a genuine OEM component designed for the RD24-100, RD27-120, RD40-130, and RD45-140 series tandem rollers, including standard, cab, open-ROPS, and DPF-equipped variants. As a direct Wacker Neuson OEM part, the is produced to the same specification as the original, ensuring a correct, consistent installation without the guesswork of cross-referencing aftermarket alternatives. This Magnet is backed by Wacker Neuson's OEM sourcing, giving you confidence that the part leaving your hands matches what came off the line. With broad coverage across the full RD tandem roller lineup, it's a go-to stocking part for dealers, rental fleets, and owner-operators running multiple machine variants.
Key Features
- Genuine OEM Magnetic Output: — Manufactured to Wacker Neuson's original magnetic field specification, so sensor readings and system responses remain accurate and consistent.
- Direct Drop-In Installation: — Engineered to match the original mounting points and connection interface on the RD series tandem roller, allowing straightforward installation without rework.
- Broad RD Series Coverage: — Fits the full RD24-100, RD27-120, RD40-130, and RD45-140 tandem roller families across standard, cab, open-ROPS, DPF, and third-generation variants.
- Consistent Signal Integrity: — A correctly functioning magnet maintains accurate speed or position feedback to the machine's control system; a failed or weakened magnet can cause erratic readings or loss of critical operational data.
- Verified Part Number: — Sourced and supplied as Wacker Neuson part 5100011971, eliminating compatibility risk when ordering for a known machine serial range.
On a tandem roller, the magnet works as part of the machine's sensing system — typically paired with a speed or position sensor to track drum rotation or travel speed. The magnetic field it generates allows the sensor to detect movement and relay that data to the machine's control circuit, which in turn governs compaction performance and drive behavior. When the magnet weakens, shifts out of position, or fails entirely, the sensor loses its reference signal, which can result in inaccurate speed readings, loss of drum control feedback, or fault codes that take the machine out of service.
