The Bomag 05729657 Relay is a genuine OEM component designed for Bomag BF-series pavers and BM-series cold milling machines, including the BF 600, BF 691, BF 800, BM 500/15, and BM 600/15. Sourced directly from Bomag, this relay matches the original specification for a straight-swap installation with no guesswork. It is confirmed to fit a broad range of paver and cold milling machine configurations across the BF 600, BF 691, and BF 800 paver families as well as BM 500/15 and BM 600/15 cold milling machines. When electrical reliability matters on a productive machine, choosing the correct OEM relay is the fastest path back to full operation.
Key Features
- OEM-Spec Switching Performance — matched to the exact coil voltage, contact rating, and pin configuration of the original relay so circuits switch cleanly under load
- Direct Plug-In Replacement — seats into the original relay socket without re-pinning or rewiring, restoring the electrical circuit exactly as designed
- Broad Paver and Cold Milling Machine Coverage — fits BF 600, BF 691, and BF 800 pavers as well as BM 500/15 and BM 600/15 cold milling machines, including EU-Flex variants
- Protects Downstream Electrical Components — a correctly functioning relay safeguards motors, solenoids, and control circuits from overload; a failed relay can cause intermittent shutdowns or prevent machine start-up entirely
- Electrical System Safety — using the correct OEM-rated relay prevents mismatched contact ratings that can lead to arcing, overheating, or damaged wiring harnesses
A relay is an electrically operated switch that allows a low-current control signal — from a switch, sensor, or controller — to open or close a high-current circuit that powers motors, solenoids, or other heavy loads on the machine. On Bomag pavers and cold milling machines, relays manage critical functions such as hydraulic solenoid activation, engine starting circuits, and auxiliary system control. When a relay fails, the circuit it controls goes dead or becomes intermittent, which can halt paving or milling operations entirely until the faulty component is replaced.
