The Bomag 740052508 Potentiometer is a genuine OEM replacement designed for Bomag cold milling machines, including the BM 1300/30, BM 1200/30, BM 2000/60, BM 2000/50, and BM 1000/30-2 series. Sourced directly from Bomag, this potentiometer matches the original component specification, ensuring correct signal output and seamless integration with the machine's control system. Verified fitment extends across multiple BM-series cold milling machine variants, covering generation and Tier 3 configurations including the BM 1300/30-2, BM 1300/30-T3, BM 1200/30-T3, BM 1200/30-2, BM 1300/30, and BM 1300 30-2.
Key Features
- OEM Signal Accuracy — manufactured to Bomag's original resistance and output specifications, ensuring the control system receives the precise positional feedback it depends on
- Direct-Fit Replacement — matches the original mounting configuration and connector interface, dropping into place without rework or adaptation
- Broad BM-Series Coverage — fits BM 1300/30, BM 1200/30, BM 2000/60, BM 2000/50, BM 1000/30-2, BM 1300/30-2, BM 1300/30-T3, BM 1200/30-T3, and related cold milling machine variants
- Cutting Depth Control Integrity — a correctly functioning potentiometer maintains accurate milling depth feedback, keeping cut tolerances consistent across the full working pass
- Electrical Safety Compliance — as a genuine OEM component, this potentiometer meets Bomag's original electrical standards, reducing the risk of erratic sensor signals that could affect machine operation or operator control
The potentiometer is a position-sensing component that translates mechanical movement — such as the travel of a leveling cylinder or depth-control actuator — into an electrical signal the machine's control unit reads to determine and regulate milling depth. On cold milling machines, accurate positional data from the potentiometer is essential for maintaining consistent cut depth and surface profile. When the potentiometer wears or fails, the control system loses reliable feedback, which can cause erratic depth control, warning faults, or a complete loss of automated grade regulation.
