Active vs. Passive ABS Wheel Speed Sensors: Understanding the Technology Behind the Wheel

I have been working with ABS wheel speed sensors for over a decade, and I can tell you that the single most common diagnostic error I see in the field is testing an active sensor with a passive sensor's method. A technician measures resistance across the terminals, gets a reading of "infinite," concludes the sensor is dead, replaces it — and the fault remains because the sensor was fine. It was just active, and active sensors do not have a coil to measure.

Technical Analysis of Active Hall-Effect ABS Wheel Speed Sensors — Iteration Relevance of Basic Model, 1st-Generation BWM Auto Parking & 2nd-Generation AK Protocol Parking Products

This article elaborates on the technical principles, structural features and iterative evolution of automotive active Hall-effect ABS wheel speed sensors. It focuses on three mainstream product generations: the basic braking-only model, the 1st-generation BWM semi-automatic parking model, and the 2nd-generation high-precision AK protocol full-scenario intelligent parking model. With consistent hardware and magnetic circuit foundations, the three products achieve progressive upgrades in signal accuracy, communication efficiency, functional safety and parking adaptability, with clear differences in performance and vehicle applicability. It also analyzes the industry trend of Hall sensors replacing traditional magnetoelectric sensors, as well as the market coexistence of three-generation products for OEM and aftermarket applications. Furthermore, it summarizes the advantages of domestic sensors in universal compatibility, cost performance and cross-border export, providing concise and professional technical support for vehicle matching, product selection and overseas market promotion.

Technical Evolution of Active Hall ABS Sensors: Ordinary / BWM / AK / KY Protocol

This article elaborates on the technical evolution of four mainstream communication protocols for active Hall ABS wheel speed sensors: Ordinary, BMW, AK and KY. It contrasts their algorithm, signal performance and applicable vehicle scenarios, covering functions from basic brake control to high-level intelligent driving, and introduces our full-series cost-effective sensors for global OEM and aftermarket businesses.
