Addressing Long Wiring Harness Challenges in Automotive

With rapid advancement of automotive intelligence and electrification, increasingly complex vehicle body functions and highly integrated domain controllers have significantly extended wiring harnesses between sensors and control units. This introduces critical challenges including elevated signal interference risks, increased costs, and compromised system reliability. 

NOVOSENSE's MT72xx series delivers robust signal integrity while effectively reducing wiring complexity and lowering harness costs. Designed for long-wiring scenarios such as door lock detection, anti-pinch window control, power tailgate position sensing, seat adjustment, and seatbelt buckle detection, these devices provide stable current output with superior anti-interference capabilities, maintaining signal reliability even in extended wiring conditions. 

High Integration & Robustness for Automotive-Grade Standards

Engineered for harsh automotive environments with strong EMI interference, the MT72xx series integrates a 100nF(only TO92S package)capacitor to enhance EMC/ESD performance, simplify peripheral configuration, and optimize BOM space, enabling flexible system architecture design. Compliant with AEC-Q100 Grade 0, the devices ensure long-term stability under extreme high-temperature conditions. 

Featuring multiple sensing polarity options (unipolar, omnipolar, latch) and adjustable sensitivity thresholds, the MT72xx series offers design flexibility to accommodate diverse magnet solutions and vehicle architectures, streamlining development and debugging processes. 

Comprehensive Resources to Accelerate Time-to-Market 

To expedite customer development, NOVOSENSEN provides dedicated MT72xx demo boards and magnetic simulation services. These resources enable rapid device validation, magnet solution matching, and cost-effective debugging, significantly shortening product deployment cycles.
