TMR Hall Effect Eliminates Drift

---

Traditional joysticks use physical contact; TMR uses magnetism. In a TMR sensor, a thin film of insulating material is sandwiched between two ferromagnetic layers. As the joystick moves, a magnet changes its position relative to these layers. This triggers "quantum tunneling" of electrons through the insulator, creating a change in electrical resistance that is translated into precise movement data.

• Zero Physical Wear: Traditional ALPS sticks use carbon-based potentiometers where a metal wiper physically rubs against a surface. This friction eventually scrapes away the material, causing "drift." TMR sensors have no touching parts, meaning they virtually never wear out.
• Higher Precision: TMR sensors provide a much higher signal-to-noise ratio than standard Hall Effect sensors, allowing for "raw" circularity tests with 0.1% error rates.
• .6-.9% Sweet Spot: I use K-Silver JS13 Pro + Joysticks because they are reliable and also stay between the sweet spot for Video Game controller calibration.
• Lower Power Consumption: TMR technology requires significantly less voltage than original Hall Effect sensors, which is critical for maintaining long battery life in wireless controllers like the DualSense or Switch Joy-Cons.
• No Deadzones: Because the sensors are so stable, manufacturers can set the "inner deadzone" to zero, providing an instantaneous response in competitive shooters.
