Stick drift is the single most common reason a perfectly good PS5 or Xbox controller ends up in a drawer. TMR thumbsticks — short for Tunneling MagnetoResistance — are the newest answer to that problem, and they go a step further than the Hall effect sticks that started replacing worn-out potentiometers a few years ago. Here's what TMR actually is, how it compares to the alternatives, and where it's available today for PS5 and Xbox controllers.

What causes stick drift in the first place?
Most factory controllers, including the standard PS5 DualSense and Xbox Series X|S pad, use potentiometers to track thumbstick movement — a physical contact point that slides across a resistive strip as the stick moves. That physical contact is exactly the problem: dust, debris, and simple friction wear the contact surface down over time, and eventually the controller reports stick movement even when your thumb isn't touching it. That's stick drift, and it's a hardware wear issue, not a software bug — which is why it eventually affects almost every controller built on potentiometer sticks.
What are TMR thumbsticks?
TMR sticks replace the physical contact point entirely. Instead of a wiper sliding across a resistive strip, a TMR sensor reads the position of a tiny magnet through quantum tunneling in a magnetic junction — a non-contact method that doesn't wear down the way a physical contact point does. Because there's nothing to physically rub against, TMR sticks resist the exact failure mode that causes drift on stock controllers.
TMR is closely related to Hall effect sensing — both are non-contact, magnet-based technologies — but TMR reads magnetic fields with higher sensitivity, which translates to tighter linearity (a more accurate 1:1 relationship between how far you push the stick and what the controller reports) and lower latency.

The short version: potentiometer sticks are the cheapest to manufacture and the most prone to failure. Hall Effect sticks fixed the wear problem for a wide range of controllers. TMR takes the same non-contact principle and adds more sensitivity and tighter tolerances on top, aimed at players who want the most precise, most durable option available today.
TMR thumbsticks for PS5: ModdedZone's DualSense Edge module
ModdedZone's Custom DualSense Edge Thumbstick TMR Module is a drop-in replacement built specifically for the PS5 DualSense Edge's interchangeable stick modules — no soldering, no permanent modification, and no special tools.

Electromagnetic TMR sensing — non-contact, drift-resistant by design
-
Rated for 5M+ cycles with consistent centering force
-
CNC-tight tolerances, low-friction bushings, premium springs, and an EMI-shielded PCB
-
Plug-and-play install directly into the DualSense Edge's module slots
-
Available in 12 finishes, from Standard Black to Clear Purple
Price: $59.99 (Standard Black) to $69.99 for color finishes, sold per unit. Shop it here: moddedzone.com/products/custom-dualsense-edge-thumbstick-tmr-module
Because it's built around the DualSense Edge's official swappable module system, this specific TMR module is designed for the Edge only — it isn't a fit for a standard PS5 DualSense, which doesn't use interchangeable stick modules.
What about Xbox?
ModdedZone's dedicated TMR module today is built specifically for the DualSense Edge's module system. On the Xbox side, the equivalent drift-resistant upgrade currently available is Hall Effect sensing — available through the MODDEDZONE PowerA Advantage Hall Effect Wired Controller for Xbox Series X|S, which starts at $109.99. It uses the same non-contact, magnet-based principle as TMR to resist drift, just without TMR's added sensitivity.
If your priority is simply eliminating wear-based drift on Xbox, Hall Effect delivers the same core benefit — no physical contact point to wear down. If TMR-specific modules become available for Xbox platforms, that changes the calculus, but as of this guide, TMR is a PS5 DualSense Edge upgrade and Hall Effect is the Xbox option.
Is upgrading to TMR or Hall Effect worth it?
Worth it if:
-
You play daily or competitively, where a drifting stick directly costs you matches
-
You've already experienced drift once and don't want to replace the whole controller again
-
You want the tightest, most consistent stick feel available for aiming or precision movement
Skip it if:
-
You play casually and replace controllers every couple of years regardless
-
Your current sticks feel fine and show no early signs of drift
Frequently asked questions
What is TMR and how is it better than Hall Effect?
TMR uses quantum tunneling in a magnetic junction to measure stick movement with extremely high sensitivity and stability. Like Hall Effect, it's non-contact, but it offers tighter linearity and better long-term drift resistance.
Do I need to solder anything to install a TMR module?
No. ModdedZone's DualSense Edge TMR modules are drop-in replacements — slide them into the Edge's existing module slots and you're done.
Will the DualSense Edge TMR module work on a regular PS5 DualSense?
No. This module is built specifically for the DualSense Edge's interchangeable stick module system. A standard DualSense doesn't use swappable modules, so it isn't compatible.
Does TMR eliminate stick drift permanently?
No sensor lasts forever, but TMR resists the wear-based failure mode far longer than potentiometer sticks, and significantly longer than most Hall Effect implementations, thanks to its non-contact design and 5M+ cycle rating.
Is there a TMR option for Xbox controllers?
Not yet from ModdedZone specifically — the current Xbox option is a Hall Effect wired controller, which shares TMR's core non-contact, drift-resistant principle. TMR modules today are built for the PS5 DualSense Edge's module system.
How do I calibrate a new TMR thumbstick module?
Detailed calibration instructions are included with every TMR thumbstick module shipped.
Ready to eliminate stick drift for good? Upgrade your DualSense Edge with ModdedZone's TMR thumbstick modules, or step up to a Hall Effect controller on Xbox.
