The content focuses on the differences between the Field75HE with magnetic keyswitches, which recently appeared as a teaser image, and the regular version of the Field75.

Conclusion: Which do you recommend, Field75HE or Field75?

Difference between Field75HE and Field75

Below is the official published difference table.

There are four differences between Field75HE and Field75 as follows

Keyswitch mechanism is magnetic

After all, the biggest difference is that the keyswitches are magnetic.

The published difference table is quoted below.

	Magnetic Switch	mechanical switch
operating principles	analog signal	digital signal
rapid trigger	Support	Not supported
Adjustable actuation	Support	Not supported
Working range	0.1-4.0mm	1.2 to 1.6mm
Minimum trigger stroke	0.1mm	1.2mm

Thus, magnetic switches are characterized by the ability to set a very fine “operating range,” which is the range from the time the switch is pressed to the time it responds.

Therefore, even a slight touch of a keyswitch can be set to output as a signal, allowing the user’s thoughts to be reflected on the PC more quickly.

It also supports “Rapid Trigger,” in which input is entered at the moment a key is pressed and is released the moment the key begins to return.

Polling rate is 8 times higher

The unit of delay from input to operation is the “polling rate.

The Field75HE is only available with a wired connection, but while the polling rate of the regular version of the Field75 was 1000 Hz, the HE has a whopping 8000 Hz.

Latency is only 0.5 ms.

This allows for a faster response.

Controlled by dedicated software

Magnetic switches are different from mechanical key switches and require more detailed settings.

We are therefore developing the NuPhy Dashboard exclusively for the Field75 HE.

At present, the control software is installed on a PC as before, but a web-based driver is scheduled for release in late 2024.

Upgraded top mount

It is top-mounted, and seems to improve the keystroke feel by mounting multiple sound-absorbing materials in addition to connecting the PCB via silicone plugs against the top plate.

Specifically, it is expressed as follows

Resonance between the internal structure and the case is greatly reduced, providing a more pleasant typing sound and relatively soft keyboard feel.

significantly reducing resonance between the internal structure and the casing, thereby providing a more pleasing typing sound and a relatively softer feel to the keyboard.

After all, when it comes to magnetic keyboards, which require faster response, “soft key feel” like gasket mounts may cause delays, so in many cases, harder top mounts and aluminum plates seem to be the choice.

However, we appreciate that doing so tends to make the keys feel as if they are being struck on a “hard board,” and that there is currently a trade-off between responsiveness and key feel.

I am very much looking forward to seeing what this “challenge” will be.
