Recently, TMR keyboards have taken the market by storm. As the latest sensor technology in magnetic keyboards, TMR (Tunneling Magnetoresistance) takes the typing and gaming experience to a whole new level – with maximum precision, low power consumption, and impressive stability.
Today we take a comprehensive look at TMR keyboards and discover why they have become a new favorite among high-performance input devices.
What is a TMR keyboard?
A TMR keyboard is a magnetic keyboard that utilizes Tunnel Magnetoresistance (TMR) technology. It uses magnetic sensor technology to detect keystrokes, offering high precision, durability, and fast response times.
What is TMR technology?
TMR (Tunneling Magnetoresistance) technology uses ferromagnetism and quantum tunneling to precisely detect signals and transmit them to the connected device.
Features of TMR technology:
High sensitivity: Detects even the smallest magnetic changes for precise inputs.
Ultra-fast response: 0.2 ms latency – ideal for gaming or industrial applications
Wide temperature range: Works reliably even in extreme environments
Low energy consumption: Efficient for wireless and mobile devices
How TMR technology works in a keyboard
TMR technology is already used in many industries, e.g. in game controllers, mice and other gaming PC peripherals.
In the keyboard sector, TMR is used in magnetic keyboards. Each key switch contains an embedded magnet, while a TMR magnetic sensor is mounted on the underlying circuit board (PCB).
When a key is pressed, the distance between the magnet and the sensor changes. The TMR sensor continuously and precisely detects this change in the magnetic field. The keyboard's microcontroller (MCU) interprets this as an analog input, enabling:
- Real-time tracking of key movement
- Adjustable trigger points
- Fast triggering: immediate reset upon releasing the button.
Advantages of TMR keyboards
1. High precision
TMR (Tunneling Magnetoresistive) sensors achieve a trigger accuracy of 0.005 mm and a response time of less than 0.2 ms. This precision and speed ensure an accurate and smooth gaming experience.
2. Low energy consumption
TMR technology consumes less energy than Hall-effect magnetic switches, thus extending the battery life of wireless keyboards – an advantage for users who need long sessions.
3. Strong stability
TMR sensors are less susceptible to temperature fluctuations and maintain stable performance even under high loads or complex environments. Users thus benefit from a reliable input experience.
4. High adaptability
TMR keyboards support extensive customization features such as RT key travel adjustment, adjustable actuation points, DKS, and analog inputs. This allows keys to be optimized to individual needs for maximum performance.
5. Broad applicability
TMR keyboards are not only suitable for e-sports and gaming, but also for office work and everyday use.
6. Long lifespan & robustness
Thanks to their contactless design, TMR sensors avoid wear and tear problems caused by metallic contacts, thus offering a longer service life – a crucial advantage for users who want to invest in a durable solution.
Why only a few brands use 2025 TMR
Although TMR technology offers many advantages, most magnetic keyboards on the market still rely on Hall-effect technology . The reasons for this are:
1. Technological maturity
TMR sensors require precise control of magnetic field changes, which places extremely high demands on algorithm tuning and hardware design.
Brands must have extensive experience in the field of magnetic keyboards and be able to mass-produce high-precision keyboards.
2. Higher development costs
TMR keyboards incur higher engineering costs due to new firmware architectures, custom signal processing algorithms, and more complex QA processes. Not all brands can bear these costs.
3. Supply chain maturity
Currently, TMR components are not yet widely available, which makes it difficult for other brands to ensure a stable supply.
TMR vs. Hall Effect vs. Mechanical vs. Optical Keyboards
| feature | TMR (Tunnel Magnetoresistance) | Hall effect (HE) | Mechanically | Visually |
|---|---|---|---|---|
| Operating principle | Resistance change due to a magnetic field that influences the current flow through metal layers | Voltage is generated by charge deflection in a magnetic field. | Physical metal contact closes circuit when pressed | The light beam (infrared) is interrupted or reflected when the key is pressed. |
| Contact type | Contactless | Contactless | Contact-based | Contactless |
| Response time / latency | ≤ 0.2 ms | ~1–2 ms | ~5–10 ms | ~1–3 ms |
| Sensitivity / Precision | Very high, recognizes small key movements | Lower than TMR, requires a strong magnetic field | Means, depending on mechanical tolerances | High, only recognizes full activation |
| Trigger point adjustment | Fully adjustable via software (0.3–3.6 mm) | Less precise, calibration usually required. | Mostly fixed | Limited; some models allow minor adjustments. |
| Durability / Lifespan | 100 million+ attacks, very stable | 100 million+ attacks, stable | Approximately 50 million keystrokes, wear and tear over time | 100 million+ keystrokes, very durable |
| Temperature stability | Excellent, insensitive to temperature fluctuations | Performance decreases with temperature changes | Means, mechanical parts can expand | Good, stable across a temperature range |
| Energy consumption | Low profile, ideal for wireless devices | Medium | N/A | Low |
| Complexity / Costs | Complex manufacturing, higher price | Medium complexity, moderate price | Simple, usually cheapest option | Medium, somewhat more expensive than mechanical |
| Applications / Areas of use | High-end gaming, analog keyboards, premium typing devices | Industrial keyboards, some high-end keyboards | Standard desktop, mechanical enthusiast keyboards | Gaming and productivity with fast response |
TMR, Hall-effect and optical keyboards are all contactless and use magnetic or optical sensors, whereas traditional mechanical keyboards use physical contacts that wear out over time.
TMR keyboards: Utilize tunnel magnetoresistance technology to detect keystrokes through changes in the magnetic field. Physical contacts are eliminated, ensuring extremely high sensitivity, low power consumption, and excellent stability across varying temperatures.
HE keyboards (Hall effect): These use Hall effect sensors that trigger keys through changes in the magnetic field. They are also contactless, but generally less sensitive and stable compared to TMR switches.
Optical keyboards: These use infrared light beams to detect keystrokes. Metal contacts are completely eliminated, ensuring reliable optical signal detection.
Conventional mechanical keyboards: Signals are triggered by the closing of physical metal contacts, which can lead to wear and tear, vibrations, and a reduced lifespan over time.
