Bomag 05566146 Inductive Proximity Switch

The Bomag 05566146 Inductive Proximity Switch is a genuine OEM component designed for Bomag BW 124 and BW 145 series single drum rollers, as well as C 815 C and C 825 C single drum rollers. Sourced directly from Bomag, this switch delivers the exact electrical and dimensional specifications your machine's sensing system requires. It installs as a direct replacement for the original unit, covering a broad range of -3, -4, and -40 generation variants across the BW 124 and BW 145 families.

Key Features

• Genuine OEM Sensing Accuracy — manufactured to Bomag's original switching-distance and output-signal specifications, ensuring the sensor triggers at precisely the correct detection threshold for your roller's control system
• Broad Single Drum Roller Coverage — fits BW 124 DH-3, BW 124 PDH-3, BW 124 DH-4, BW 124 DH-40, BW 124 PDH-40, BW 145 D-3, BW 145 DH-3, BW 145 PDH-3, BW 145 DH 40, BW 145 PDH 40, C 815 C, C 825 C, and additional variants in these families
• Drop-In Replacement — matches the original connector type, thread size, and mounting configuration so this switch fits the existing bracket and harness without alteration
• Protects Machine Control Systems — a failed or out-of-spec proximity switch can cause erratic drum-speed readings, incorrect vibration control responses, or disabled safety interlocks; replacing with a genuine OEM unit restores normal electronic control behavior
• Electrical Safety Compliance — as a safety-circuit component, using the correct OEM switch maintains the original switching frequency and output voltage range, keeping the machine's interlock and control logic operating within its designed parameters

An inductive proximity switch detects the presence or position of a nearby metal target — such as a rotating drum hub or drive shaft — without physical contact, using an electromagnetic field to trigger a switching signal. In a single drum roller, this signal feeds into the machine's electronic control unit to monitor drum rotation, vibration frequency, or drive engagement status. When the switch weakens, drifts out of range, or fails entirely, the control system may receive false signals or no signal at all, leading to incorrect machine behavior, diagnostic fault codes, or the disabling of vibration and drive functions.
