TMR Keyboards list

hall effect vs tmr hall effect vs tmr

After a year full of Hall Effect keyboards there are now TMR keyboards popping up. But how’s that different than Hall effect keyboards with magnetic switches?

TMR is basically a slight upgrade from the Hall effect technology. In the case of the first TMR keyboard I’ve used – Monsgeek FUN60 Ultra the switches are just regular hall effect switches. But the PCB of the keyboard uses TMR magnetic sensors instead of Hall effect magnetic sensors.

And what’s the difference between TMR and Hall effect sensor in the context of mechanical keyboards?

In TMR keyboards you can use regular mechanical switches and they will work fine, but they don’t have magnets, so all the magnetic switch features like Rapid Trigger, adjustable actuation etc won’t work then.

TMR switches

The switches used in TMR sensor keyboards are exactly the same as the ones used in Hall effect keyboards. TMR and HE keyboards are different in a way that they have a different position of the magnet, but the magnetic switches used there are the same. So you can use Gateron Jade, Jade Pro, Lekker V2 V60 and other magnetc switches freely in HE keyboards like Wooting 60HE and in TMR keyboards like Womier SK75 TMR.

One thing that’s different is a sensor position on some PCBs, so there are Gateron KS20 and KS37 standard witches. The KS20 standard is much more popular and the KS37 is mainly used in Keychron HE/TMR keyboards. So you can’t use a Gateron Jade or Lekker V60 in a Keychron Q5 HE for instance.

The first released keyboard with TMR sensors seems to be the Monsgeek FUN60 Ultra (there are wired and wireless versions).

Comparison of TMR keyboards, all of them are hotswappable

Note: Turns out all of the Keychron K HE and Q HE series have TMR sensors – but they have been advertised misleadingly as “HE” keyboards, because that term was much more popular at the time when Wooting 60HE and other competitors started releasing HE keyboards. So they just went with it, despite having TMR technology.

Keychron’s keyboard definitely have the best software out of these, with Womier at the second place in my opinion.

Keydous NJ98-CP V3 HE is the only 98%/full sized TMR keyboard on the market as of 2025.

There are now also a few keyboards released with inductive switches such as Ducky One X and Epomaker Magcore 87. This is yet another technology with different sensors.

Uses for TMR sensors

TMR (Tunnel Magnetoresistance) sensors can be used across a surprisingly wide range of gaming hardware — basically anywhere precision movement or position detection is needed. Here’s a breakdown of where and how TMR sensors can be applied:

Device / ApplicationTMR Sensor RoleKey Benefit
Gaming keyboardsLinear sensors for detecting key press depth or actuation pointUltra-low latency and precise keystroke detection (better than Hall sensors)
Game controllersAngle or position sensors for thumbsticks, trigger buttonsHigher precision and consistency for analog input control
Mice (mouse wheels & motion tracking)Angle sensors for scroll wheels or linear movement trackingSmooth, lag-free scroll and cursor movement
Steering wheels (driving simulators)Angle sensors for wheel rotation and positionRealistic steering feedback with accurate motion tracking
Pedals (racing gear)Linear sensors for throttle, brake, or clutch pedalsPrecise input proportionality and reduced input noise
AR/VR headsets and controllersAngle sensors for tracking hinge positions, orientation, or motionImproved spatial accuracy and responsiveness
WebcamsPosition or proximity sensorsAutomatic lens cover detection or auto-focus mechanisms
Foldable or hinged devices (e.g. AR glasses)TMR hinge sensorsDetect open/closed or in-use states
Custom gaming peripherals (e.g. flight sticks, simulators)Angle/position sensorsEnhanced accuracy in motion-sensitive components

TMR sensors excel where traditional Hall sensors start to show limits — they’re up to 10× more sensitive, consume less power, and maintain better stability over temperature or magnetic drift. That’s why they’re increasingly showing up in next-gen gaming gear, particularly premium keyboards and controllers.
