Heavy Duty Truck Air Brake System Fluid Pressure Sensor Replacement for Scania DAF Mercedes | WABCO SB220 OEM 4410400110

Product Overview The 4410400110 / SB220 Air Brake and Pneumatic System Pressure Sensor is a high-precision heavy-duty safety component engineered as a premium aftermarket replacement for Scania, DAF, and Mercedes-Benz commercial truck fleets. Designed to meet strict industrial diagnostic telemetry baselines, this sensor is primarily integrated into the truck’s pneumatic brake circuit manifolds, multi-circuit protection valve bodies, or EBS/ABS control blocks. By reading instantaneous pressure levels and converting them into precise electronic telemetry for the central vehicle ECU, it provides the critical feedback needed to guarantee proper braking force distribution, prevent wheel lockup, and manage stable chassis pneumatic infrastructure. Technical Specifications Primary WABCO Cross-Reference Code: 4410400110, 441 040 011 0 Industry Designation Model: SB220, SB 220 Series Transducer Component Class: Inductive/Piezoresistive Fluid & Air Circuit Pressure Sensor Sender Housing Design: Heavy-duty, anti-oxidizing brass connector base fused with a high-impact polymer wire plug shield Terminal Array: Premium weather-sealed pins matched to factory harness snap configurations Condition: Brand New Premium Aftermarket Replacement Vehicle Family & System Compatibility Matrix This replacement fluid-pneumatic tracking probe matches factory resistance curves and indexing dimensions, enabling stable drop-in replacement across prominent commercial transport chassis line-ups: Truck Manufacturer & Family System Integration & Application Profiles Scania Trucks (P / G / R / T Series Platforms) Fits international heavy haulage and distribution models running WABCO-based EBS (Electronic Braking System) or pneumatic reservoir monitor loops. DAF Trucks (XF 95 / XF 105 / CF Series) Direct fitment for Class-8 long-haul highway transport tractors utilizing SB220-indexing parameters on the main air-line protection network. Mercedes-Benz Trucks (Actros / Axor Configurations) Compatible with heavy-duty distribution rigs and vocational tippers operating matching circuit-valve pressure sensing configurations. Performance Benefits Restores Brake System Response: Directly resolves common pneumatic circuit failures including slow brake deployment, uneven multi-axle braking balance, or erratic dashboard brake system warning lamps. High Vibration Isolation: Internal micro-circuits are reinforced against harsh chassis vibration, frame twist, and severe industrial job-site terrain shaking. IP67 Waterproof Enclosure: Engineered with tight sealing gaskets to isolate electrical components from high-pressure under-chassis washing, deep puddles, wet mud, and corrosive winter road de-icers. Maintenance Tip: In heavy-duty truck logistics routines, a failing 4410400110 / SB220 sensor usually triggers an ABS/EBS fault code on the driver dashboard or forces the vehicle into a conservative air backup safety mode. Because this sensor is positioned under the chassis near the main pneumatic air lines, it is continuously subjected to aggressive moisture condensation, road grime, and fine air-system oil film scaling. Before replacing this component, make sure the vehicle’s air reservoirs are fully bled to zero pressure and the wheels are securely chocked. Clean all accumulated grime around the thread block, verify the seal ring sits flush, and push the wire loom plug home until the locking tab securely clicks into place to maintain a fully moisture-isolated connection.
