Magnetic Keyboards: TMR Or HE?

In the field of keyboards, innovation never stops. From mechanical switches to magnetic and optical switches, the options continue to grow. Now, it’s not just Hall Effect magnetic keyboards—TMR magnetic keyboards have arrived! It uses advanced tunnel magnetoresistance effect technology to make every keystroke accurate and smooth. Moreover, this new TMR sensor magnetic keyboard has a long lifespan and is super energy-efficient.

What is a TMR keyboard?

A TMR keyboard is a type of magnetic keyboard that uses Tunnel Magnetoresistance (TMR) sensors to detect key presses by detecting the changes in resistance.

TMR sensors are based on a quantum mechanical phenomenon where the electrical resistance of a material changes in response to an external magnetic field. It can be very sensitive to changes in the magnetic field and can measure weak magnetic field changes.  

Why Use TMR for Magnetic Keyboards?

TMR sensors are generally more sensitive and more accurate, and especially for battery-powered devices, they generally consume less power too. 

With the TMR magnetic keyboard, you can enjoy:

1. Unparalleled Precision

Compared to Hall Effect sensors, TMR sensors are far more sensitive—possibly up to 1,000 times more. With settings as small as 0.01 mm, this enhanced sensitivity enables incredibly accurate and precise control over actuation points.

2. Ultra-low Latency

TMR sensors are incredibly sensitive and can provide super-fast and responsive performance. It can be a great choice for the game.

3. High Stability

The TMR sensor offers stable performance in wireless conditions, ensuring precise tracking and low latency. This makes it perfect for competitive gaming, providing smooth, reliable control and longer battery life.

4. Lower Power Consumption

The TMR sensor consumes less power, which is especially important for wireless keyboards. This reduced power consumption extends battery life, enhancing the practicality of tri-mode or wireless models.

TMR VS Hall Effect 

Feature	TMR (Tunnel Magnetoresistance)	Hall Effect
Principle	Change in resistance based on the alignment of magnetizations in ferromagnetic layers.	Voltage generated due to the interaction of current and a magnetic field.
Sensitivity	Higher sensitivity, especially for detecting small changes in magnetic fields.	Generally lower sensitivity, suitable for moderate magnetic field detection.
Accuracy	More precise, offering higher resolution and cleaner signal output.	Less precise; often requires calibration for optimal performance.
Technology	More complex and sophisticated, typically used in high-performance applications.	Simpler and more widely adopted in various industries.
Cost	More expensive due to advanced fabrication processes and materials.	Typically cheaper due to simpler design and widespread use.
Applications	Hard drives, advanced sensors, high-end switches, and precision devices.	Position sensors, speed sensors, current sensing, and consumer electronics.
Wear Resistance	Contactless and more stable under varying conditions, with minimal drift over time.	Contactless design reduces wear but can be affected by temperature and calibration.

Hall Effect Sensors: The Pioneer of Magnetic Keyboards

Hall Effect sensors have been around for decades and are widely used in various industries, from automotive to consumer electronics. In keyboards, Hall Effect sensors work by detecting changes in magnetic fields caused by the movement of a magnet attached to each key.

TMR Sensors: The Next Generation of Magnetic Sensing

While Hall Effect sensors are well-established, TMR (Tunnel Magnetoresistance) sensors represent the next step in magnetic sensing technology. TMR sensors are based on a quantum mechanical phenomenon where the electrical resistance of a material changes in response to an external magnetic field.
