Overview These precision 5mm rare earth magnets are essential components for cam and crank position sensor setups in custom engine builds and EFI conversions. Whether you're fabricating trigger wheels for an LS swap, building a custom reluctor setup for a turbo RB engine, or converting a classic motor to modern engine management, these neodymium magnets deliver the magnetic field strength required for reliable RPM sensing at all engine speeds. Technical Specifications Part Number: HT-010602 Dimensions: 5mm diameter x 2mm height Material: Neodymium rare earth magnet Temperature Rating: Suitable for engine bay applications Magnetic Strength: High-grade neodymium for reliable sensor triggering Why You Need This Cam and crank position sensing is absolutely critical for any modern engine management system, yet it's often overlooked until you're deep into a build. These rare earth magnets are specifically sized for custom trigger wheel fabrication and sensor applications where OEM components aren't available or suitable. In LS conversions into Japanese chassis, turbo SR20 builds, or classic car EFI swaps, you'll frequently need to create custom timing references. The 5mm diameter suits most fabricated trigger wheels and sensor mounting scenarios we see at Billy's. Too weak a magnet and you'll get inconsistent RPM reading at idle or high RPM dropout - potentially catastrophic with boost. These neodymium units provide the field strength needed for clean, reliable triggering through Haltech's crank and cam inputs, whether you're running a simple missing tooth setup or complex multi-tooth pattern for sequential injection and individual coil control. ECU & System Compatibility Compatible with all Haltech ECU trigger inputs including Elite 550, 750, 1000, 1500, 2000, and 2500 series, plus Nexus R3, R5, and Rebel units. These magnets work with both magnetic reluctor sensors and Hall effect setups depending on your trigger wheel design and sensor choice.
