The Wacker Neuson is a genuine OEM Magnetic Ring designed for the RD7 series walk-behind tandem rollers and the DPU4045, DPU4545, DPU5045, and DPU5545 series diesel reversible vibratory plate compactors. Sourced directly through Wacker Neuson's authorized parts network, this magnetic ring meets the exact specifications required for proper sensor and control system function on these machines. It is a direct-fit replacement for all listed RD7 and DPU variants, including European and North American configurations. Whether you are servicing an RD7He, RD7Heh, DPU5545Heh, or DPU4545He, part number is the correct OEM-specified component.
Key Features
- Genuine OEM Magnetic Integrity — Manufactured to Wacker Neuson's specified magnetic field strength, ensuring accurate signal output to speed sensors and vibration control systems on both roller and plate compactor applications.
- Drop-In Fitment Across Multiple Platforms — Engineered to install directly onto the shaft assembly without machining or modification, matching the original mounting interface on all compatible RD7 and DPU series models.
- Broad Model Coverage — Confirmed fitment across the RD7 tandem roller family (including RD7H, RD7He, RD7Heh, RD7Hehf, and RD7Hehfb variants) and DPU4045, DPU4545, DPU5045, and DPU5545 reversible vibratory plate compactors in EU and US configurations.
- Preserves Vibration and Speed Control Accuracy — A degraded or cracked magnetic ring causes erratic or absent sensor readings, which can disrupt automatic vibration control and drum speed monitoring — correct operation restores full machine response.
- OEM Part Number Confidence — Carrying Wacker Neuson part number 5000129025, this ring is traceable to the original equipment specification, eliminating guesswork when cross-referencing across the wide range of DPU and RD7 model variants.
The magnetic ring is a precision component mounted on a rotating shaft — typically the exciter or drum drive shaft — where it works in conjunction with a proximity or Hall-effect sensor to generate speed and position signals used by the machine's control system. On reversible vibratory plate compactors, these signals govern the automatic vibration adjustment and travel direction logic; on tandem rollers, they contribute to drum speed monitoring and operator control feedback. When the magnetic ring becomes cracked, demagnetized, or physically damaged, the sensor loses a consistent signal reference, which can cause erratic machine behavior, loss of vibration control, or fault codes that prevent normal operation.
