GT101 Style High Frequency Hall Effect Sensor Size: 18mm Diameter

Overview

The Haltech GT101 Style High Frequency Hall Effect Sensor delivers precision RPM and position sensing for high-performance applications where reliability at extreme speeds is non-negotiable. This 18mm diameter sensor provides accurate triggering up to incredibly high RPM limits, making it the go-to choice for drag racing builds, circuit cars, and any application where engine speeds regularly exceed standard sensor capabilities.

Why You Need This

Standard inductive sensors start failing as RPM climbs - signal quality degrades, timing becomes erratic, and eventually you get complete signal dropout just when your engine needs precise timing most. Hall effect sensors solve this fundamental problem by providing clean digital signals regardless of RPM. The GT101 style sensor is specifically designed for extreme applications where engines regularly see 8,000+ RPM, whether that's a built LS spinning to 7,500 on the limiter, a screaming SR20 reaching 9,000 RPM, or a race-prepped Honda hitting stratospheric speeds.

The 18mm diameter makes this sensor perfect for aftermarket trigger wheels and custom crank sensor installations. We've fitted these to everything from drag-spec RB30 builds where the stock sensor simply couldn't keep up, to circuit-prepared BMW M engines running aggressive cam timing that demands rock-solid crank position accuracy. The robust hall effect design also handles vibration and electromagnetic interference far better than conventional sensors - crucial when you've got high-output ignition systems and alternators running nearby.
