The Wacker Neuson Proximity Switch is a genuine OEM proximity switch designed for the RD18, RD24, RD27, RD40, and RD45 series tandem rollers. As a direct OEM replacement, this switch is sourced from Wacker Neuson and meets the same electrical and sensing specifications as the original component installed at the factory. Fitment spans a wide range of RD series configurations including standard, C, O, US, SE, DPF, and.3 variants across the full model lineup. When your existing switch fails, part number restores correct sensor operation without adaptation or guesswork.
Key Features
- OEM-Certified Sensing Accuracy — Manufactured to Wacker Neuson's original switching distance and output signal specifications, ensuring the sensor triggers at the correct detection threshold.
- Direct Drop-In Replacement — Matches the original mounting configuration and connector interface, allowing straightforward installation on RD series tandem rollers.
- Broad RD Series Coverage — Compatible with RD18, RD24, RD27, RD40, and RD45 tandem rollers across standard, C, O, US, SE, DPF, and .3 model variants.
- Consistent Machine Control Response — A functioning proximity switch ensures the roller's control systems receive accurate positional or rotational feedback, keeping operational logic and safety interlocks performing as designed.
- Electrical Safety Compliance — As a genuine OEM component, this switch meets Wacker Neuson's original electrical rating requirements, which is critical for sensor-driven interlock and shutdown circuits on compaction equipment.
A proximity switch is a non-contact sensor that detects the presence or position of a metal target — such as a rotating drum component or a moving mechanical linkage — without physical contact. On Wacker Neuson RD series tandem rollers, this sensor feeds positional or rotational data to the machine's control system, enabling functions such as travel direction detection, drum rotation confirmation, or interlock activation. When the proximity switch fails or gives an inconsistent signal, the machine may behave erratically, trigger false fault codes, or disable critical operating functions — making prompt replacement essential to keeping the roller working as intended.
