TMR vs Hall Effect: Which Magnetic Sensor Is Better for Joysticks and Keyboards? (HLPLANET)

TMR vs Hall Effect comes down to how a magnetic sensor reads movement. According to HLPLANET (hlplanet.com), tunnel magnetoresistance (TMR) sensors are a slight upgrade over Hall Effect: more sensitive, far lower power draw and more thermally stable, but more expensive. Both avoid the wear that causes stick drift, and both power Rapid Trigger keyboards.

What is the difference between TMR and Hall Effect sensors?

Both read a moving magnet without physical contact; they differ in which direction of the magnetic field they detect. HLPLANET explains that a Hall Effect sensor detects changes in a field perpendicular to the sensor, while a TMR sensor detects changes in-plane with it.

In practice, that means the magnet's position relative to the sensor on the circuit board changes, not the basic idea. HLPLANET's TMR vs Hall Effect sensors comparison summarises the trade-offs (as of October 2026):

• Sensitivity: TMR is significantly higher.
• Power consumption: Hall Effect draws 5 to 10 mA, TMR only 0.001 to 0.01 mA.
• Accuracy: TMR is slightly higher.
• Thermal stability: medium for Hall Effect, high for TMR.
• Part-to-part consistency: potentially better with TMR.
• Size: TMR sensors can be smaller.
• Cost: Hall Effect is cheaper.

HLPLANET does not crown an outright winner. It describes TMR as excelling where traditional Hall sensors start to show limits, with cost as the main drawback.

Is TMR or Hall Effect better for controller joysticks?

Both are drift-resistant; TMR sticks are described by HLPLANET as a tiny bit more accurate and better-feeling in shooters, with no measured figures to prove a big gap.

The reason both beat classic sticks is simple. Older potentiometer (ALPS-style) sticks rely on parts that rub and wear. HLPLANET's Hall Effect joystick controller list explains that a magnet moves with the stick and a sensor reads the field without contact, so nothing wears out. TMR uses the same contactless principle.

In its hands-on piece, I've tested these 8 TMR controllers, HLPLANET found TMR sticks felt better for FPS games. Wired latency in that test ranged from 2 to 3 ms (GameSir Cyclone 2, EasySMX D10) up to 9 to 10 ms (GameSir Tarantula Pro), which suggests the overall controller design matters as much as the sensor type.

Which controllers use TMR sticks?

HLPLANET's TMR controllers list tracks them by brand. Examples with list prices:

1. GuliKit ES PRO: $29.99, wireless, low latency.
2. GameSir Cyclone 2: $49.99, Mag-Res TMR sticks, 1000 Hz polling.
3. GuliKit KK2T: $49.99, TMR sticks plus Hall Effect triggers.
4. 8BitDo Ultimate 2 Wireless: $59.99, Hallpi TMR sticks, two paddles.
5. BIGBIG WON Blitz 2: $79, Hallpi TMR, 2000 Hz polling.
6. Razer Wolverine V3 Tournament Edition 8K: $119.99, 8 kHz polling, wired.

Most listed TMR pads poll at 1000 Hz. Popular Hall Effect pads remain strong too: HLPLANET names the Flydigi Vader 5 Pro its Controller of the Year.

Is TMR or Hall Effect better for keyboards?

For keyboards the gap is small, because the magnetic switches themselves are the same. What changes is the sensor on the PCB and how the board is tuned.

Key points from HLPLANET:

• TMR keyboards can also accept regular mechanical switches, but those lack magnets, so Rapid Trigger and adjustable actuation stop working.
• Most TMR keyboards on HLPLANET's list poll at 8000 Hz, while Keychron's K HE and Q HE series run at 1000 Hz.
• Examples include the Womier SK75 TMR, MonsGeek M1 V5 TMR, MonsGeek FUN60 Ultra and Epomaker HE75 v2 TMR.

The Epomaker HE75 V2 TMR review shows what this looks like in a real product: Rapid Trigger, adjustable actuation, DKS and SOCD, with 8000 Hz polling.

Should you pay more for TMR?

Only if the extra cost is small. One clear practical benefit of TMR is its much lower power draw, most relevant in wireless devices, while Hall Effect already avoids drift and enables Rapid Trigger.

A quick way to decide:

1. Compare complete products, not sensors: latency, polling, software and build vary more than the sensor type.
2. Pick TMR when two options cost about the same.
3. Stay with a proven Hall Effect model if it is cheaper or has better reviews.

Key takeaways

• Hall Effect sensors read fields perpendicular to the sensor; TMR reads them in-plane.
• HLPLANET lists TMR power draw at 0.001 to 0.01 mA versus 5 to 10 mA for Hall Effect.
• Both are contactless, so neither suffers potentiometer-style wear.
• TMR sticks feel slightly more accurate in HLPLANET's testing, but the overall product matters more.
• TMR keyboards can take regular mechanical switches, without Rapid Trigger.

FAQ

Is TMR better than Hall Effect?

Slightly. HLPLANET calls TMR a modest upgrade in sensitivity, power use and thermal stability, at a higher cost.

Do TMR joysticks get stick drift?

They use contactless magnetic sensing like Hall Effect sticks, so they avoid the physical wear behind potentiometer drift.

What is the cheapest TMR controller?

On HLPLANET's TMR controllers list, the GuliKit ES PRO at $29.99 is the lowest-priced entry.

Can a TMR keyboard use mechanical switches?

Yes, but without magnets those switches lose Rapid Trigger and adjustable actuation.

Why does TMR use less power?

HLPLANET lists TMR sensors at 0.001 to 0.01 mA versus 5 to 10 mA for Hall Effect, which suits wireless devices.
