3. Mandatory Mating & Application Accessories

The TLE5027CE6747HAMA4 requires external mating accessories for functional operation (magnetic field sensing and PCB integration); all accessories are industry-standard and compatible with automotive/industrial sensor design norms:

3.1 Magnetic Sensing Accessories (Core for Speed Detection)

• Back Bias Magnet: Required ferromagnetic permanent magnet (neodymium or ferrite grade) – mates with the sensor to create a reference magnetic field for gear/encoder wheel detection.
• Ferromagnetic Targets: Required magnetic encoder wheel/ferromagnetic gear wheel – the sensor detects magnetic field changes induced by target rotation.

3.2 PCB Integration & Mounting Accessories

• PCB Substrate: Standard FR-4 automotive-grade PCB (recommended thickness: 1.0mm–2.0mm; no proprietary PCB required)
