Automobile Parts Sensor

BMW ABS / DSC Brake Pressure Switch – Automobile Parts Sensor BMW braking systems depend on accurate pressure signals for anti‑lock braking (ABS) and dynamic stability control (DSC). A faulty brake pressure sensor can cause warning lights on the dash, reduced braking performance, or loss of stability control. The automobile parts sensor from Flying Bull is a high‑performance ABS/DSC pressure switch designed for BMW models. It comes with compatible part numbers including 34521164458, 55CP09‑03, 30793669, 9173055, 89637‑0C010, 43CP5‑2, and 55CP01‑03. This sensor is specifically engineered for BMW models – E46, E60, E61, E63, E64, Z3, E36, Z4, and E85. It is a go‑to choice for BMW owners and mechanics needing a reliable braking system sensor. First launched on July 20, 2021, this automobile parts sensor has earned a reputation for durability and precision. Its compact packaging (3 x 1.97 x 1 inches) makes storage and transport easy. At just 0.8 ounces, it is lightweight and easy to handle during installation. Functional features Operation – This device has a normally closed contact design. When pressure is low (brake not applied), the circuit stays closed (conducting). Once pressure reaches a set point (e.g., 10 bar / 145 psi), the contact opens by itself. This instantly triggers the ABS/DSC system to react quickly to braking demands. The sensor is easy to use with simple on‑off operation and straightforward touch control. Its single‑channel circuit design ensures signals are sent promptly and reliably. Performance parameters – Rated current: 5 mA. Operating voltage: 120 microvolts (μV) – an extremely low‑power design. Measurement accuracy: up to ±0.5% FS (full scale). This allows the sensor to catch tiny changes in brake system pressure in real time. The ABS/DSC system receives precise data, preventing braking delays or false activations caused by faulty signals. Protection – The housing is made from high‑quality acrylonitrile butadiene styrene (ABS) with a special wear‑resistant treatment. This keeps it safe from oil, dirt, and dust around the brake system. The sensor boasts an IP6K9K protection rating and has passed high‑pressure water jet tests (using 80°C hot water at 14‑16 bar pressure) and high‑temperature steam cleaning tests. This makes it well‑suited for the tough conditions under a car’s chassis. Installation and compatibility Installation method – The sensor comes with plug‑in connectors and screw terminals, providing a secure, vibration‑resistant connection. No extra wiring adjustments are needed during installation – just connect it directly to the original vehicle interface. It fits right into the BMW brake system’s wiring setup. The sensor is compact (3 x 1.97 x 1 inches) and weighs only 0.8 ounces, so it fits easily in the tight space of a vehicle’s brake lines without getting in the way of other parts. Interchangeability – This model is designed specifically for BMWs. It works seamlessly with the brake systems of popular models including the E46, E60, E61, E63, E64, Z3, E36, Z4, and E85. You can replace the original parts with this one without any modifications. A full OEM part number mapping table is provided, including 34521164458, 55CP09‑03, and 30793669. This makes it easy to quickly find the right part for your model and ensure a proper replacement. Quality and certification Lifespan – This product has undergone 1 million cycle stress tests and works reliably in temperatures ranging from ‑40°C to 85°C. Its mean time between failures (MTBF) exceeds 10,000 hours, meeting the long‑term service requirements of automotive parts. It has passed 500‑hour salt spray tests and 500‑hour humidity cycle tests (at 40°C and 95% humidity). This ensures it stays structurally stable and performs consistently even in harsh environments. Certification standards – The sensor complies with ISO/TS 16949 automotive quality management system standards, as well as CE and RoHS environmental certifications. The materials are free from harmful substances like lead and mercury, meeting the entry requirements of major global automotive markets. Failure rate and warranty – The manufacturer offers a one‑year warranty. Thanks to strict factory inspections – each sensor undergoes pressure calibration and performance testing – the product failure rate is kept below 0.3%. Packaging and after‑sales service Packaging method – The sensor is packed with anti‑static bags, cushioning foam, and cardboard. This effectively prevents static damage and physical impacts during shipping. OEM label customization is available – you can print model numbers, certification logos, brand information, and more. This makes inventory management and product tracking simpler. Delivery time – Regular models are well‑stocked and can be shipped within 5‑7 business days after order confirmation. For large orders, advance scheduling ensures on‑time delivery. Flying Bull’s automobile parts sensor is 100% brand new, manufactured in Zhejiang, China, and backed by a 1‑year warranty. Delivery takes 5–7 working days. Choose Flying Bull for reliable BMW ABS/DSC brake pressure monitoring.
