With the explosive growth of automotive electrification, industrial automation, and IoT devices, the market demand for magnetic sensors—which serve as a bridge between the physical and digital worlds—continues to rise. To help global OEMs, distributors, and solution providers resolve inventory backlogs and improve cash flow, Shenzhen Mingjiada Electronics Co., Ltd. (hereinafter referred to as “Mingjiada”) has announced that it will offer high-price buyback services for all types of surplus and obsolete magnetic sensor products on a long-term basis for the global market.
Leveraging its strong financial resources and professional technical team, Mingjiada not only provides component supply services but is also committed to building a green and environmentally friendly circular economy chain for electronic components.
Core Acquisition Focus: Automotive and Industrial-Grade Magnetic Sensors
Magnetic sensors are widely used in fields such as position detection, angle measurement, current sensing, and speed detection. Mingjiada prioritizes the acquisition of magnetic sensors with high reliability and precision (particularly those compliant with the automotive-grade AEC-Q100 standard). Specific types include:
Hall Effect Sensors: Including switch-type, latch-type, and linear Hall sensors, used for proximity switches, level conversion, and position sensing.
Magnetic Position Sensors: Including linear displacement sensors, rotary angle sensors, and 3D magnetometers, widely used for detecting steering wheel angle, accelerator pedal position, and motor rotor position.
Current Sensors: Based on the Hall or magnetoresistive effect, used for current monitoring in BMS battery management, motor drives, and photovoltaic inverters.
RPM/Speed Sensors: Used for automotive wheel speed and engine crankshaft/camshaft position detection.
Electronic Compasses/Magnetometers: Used in navigation systems and drone orientation.
List of Priority Acquisition Brands: Covering Global Top OEMs
Mingjiada Electronics is actively seeking to purchase magnetic sensors from the following top international and domestic brands. We accept brand-new, factory-sealed units, factory surplus stock, full unopened reels, and dismantled components from legitimate sources (must be in good working condition):
1. Automotive and Industrial Sensing Giants (Automotive-Grade Special Section)
With the increasing penetration of new energy vehicles, there is a massive demand for automotive-grade chips. Mingjiada offers high-price cash purchases for automotive-grade magnetic position sensors and current sensors from the following brands:

NXP: We purchase its KMA/KMA series angle sensors and ASL series linear position sensors, commonly used in EPS and accelerator pedal applications.
Allegro MicroSystems: We purchase its A13xx series angle sensors and A12xx series speed sensors, particularly wheel speed sensors featuring “true zero-speed” technology, such as the A1333, A1356, and A1235.
Melexis: Focus on acquiring its patented Triaxis® 3D magnetometer technology chips, including the MLX903xx series and the next-generation MLX904xx series, suitable for steering wheel angle and chassis height detection.
Bosch: Acquire its magnetometers used in MEMS IMUs and automotive inertial measurement units.
2. Diversified and High-Precision Sensor Brands
Beyond the automotive sector, Mingjiada also focuses on magnetic sensing resources for industrial and consumer electronics:
Vishay: Specifically acquiring its full range of magnetic sensors, including Hall-effect switches (such as the SS495 series), position sensors, and angle sensors for motor control. Vishay’s products are renowned in the industry for their high reliability and AEC-Q automotive certification.
Silicon Labs: We source their high-sensitivity Hall-effect magnetic sensors, suitable for IoT node applications such as door/window sensors, battery monitoring, and position sensing.
Texas Instruments (TI): We source the DRV50xx series of Hall switches and the TMAG517x series of 3D linear sensors, known for their excellent cost-performance ratio.
AKM (Asahi Kasei): Acquire their Hall ICs and magnetometers, which dominate the Japanese supply chain.
