As a high-sensitivity Hall element, the NHE312 adopts evaporated indium antimonide (InSb) thin-film technology and delivers outstanding performance in low magnetic field environments:

1. High Sensitivity for Weak Magnetic Field Scenarios

Under conditions of Vc=1V and B=50mT, it features an excellent typical output voltage VH, ranging from 196~428mV, enabling accurate capture of weak magnetic field changes. Whether for rotor position detection in brushless motors or signal acquisition in low magnetic flux sensors, it can output clear and stable voltage signals, avoiding detection errors caused by insufficient sensitivity.

2. Low Offset Voltage for Purer Signals

At zero magnetic field (B=0mT), the offset voltage Vo is only ±7mV, far lower than conventional Hall elements, reducing signal interference. It can be directly connected to the post-stage amplifier circuit without the need for additional compensation circuit design, simplifying hardware development.

3. Multi-Grade Voltage Options for Flexible Adaptation

Classified into multiple grades (Grade 4~9) based on output voltage VH, covering a range of 168mV~428mV, it allows selection according to actual magnetic field intensity and detection precision requirements. For example, high grades (Grade 8~9) are selected for weak magnetic field scenarios, and medium grades (Grade 5~7) for regular scenarios, enabling adaptation to different projects without circuit modification.

Industrial equipment, automotive electronics, and other scenarios impose high requirements on the environmental adaptability of components, and the NHE312 excels in stability:

1. Wide Operating Temperature Range

The operating temperature ranges from -40℃ to 110℃, and the storage temperature from -40℃ to 125℃, enabling adaptation to harsh environments such as low outdoor temperatures and high temperatures in industrial equipment. Even in scenarios with drastic temperature changes, the temperature drift coefficient (VH temperature coefficient αHI: -1.8%/℃) remains stable, ensuring no significant fluctuations in detection accuracy.

2. Rugged and Reliable Sip Package

It adopts a Sip-type package with a 4-pin design featuring reasonable pin spacing for easy soldering. The compact package structure offers strong vibration and impact resistance, making it suitable for installation in high-vibration equipment such as brushless motors and automotive sensors.

3. Mature Packaging Solution

Supplied in bulk packaging (1000 units per bag, 30000 units per carton), it facilitates bulk procurement and automated surface mount technology (SMT) production, with a stable and guaranteed supply chain.

The high performance and high reliability of the NHE312 enable it to deliver value across multiple sensing fields:

1. Brushless Motors

Used for rotor position detection in motors, it accurately outputs magnetic pole switching signals, cooperating with driver ICs to achieve smooth speed regulation and commutation of motors. High sensitivity ensures accurate detection even during low-speed operation, while low offset voltage reduces rotational speed fluctuations.

2. Position/Rotation Sensors

For non-contact position detection (e.g., door/window switches, robotic arm positioning) and rotational angle sensors (e.g., auxiliary detection for encoders), the non-contact design extends service life, and the wide-temperature characteristic adapts to industrial environments.

3. Current Sensors

Detects tiny currents in circuits (measured indirectly through magnetic fields generated by currents), suitable for current monitoring scenarios in power management and industrial control. High sensitivity allows it to capture weak magnetic fields corresponding to small currents.

4. Other Magnetic Flux Sensors

Such as magnetic field strength meters, magnetic card identification modules, and non-contact switches – whenever low magnetic field detection is involved, the NHE312 enables precise signal acquisition.

Selection Recommendations

• Select voltage grades based on magnetic field intensity (choose high grades for weak magnetic fields and low grades for strong magnetic fields);

• For projects with strict environmental protection requirements, prioritize the NHE312-HF halogen-free and lead-free version.

Wiring Notes

• Pins 1 and 3 are input terminals, while Pins 2 and 4 are output terminals. Pay attention to pin definitions during soldering to avoid reverse connection;

• Minimize pin wiring length to reduce the impact of electromagnetic interference on signals.

Driving Method

It is recommended to use 1V constant voltage drive or 1mA constant current drive. Avoid input current exceeding the upper limit of 20mA to prevent component damage.

Temperature Drift Compensation

When used over an ultra-wide temperature range (e.g., the full range of -40℃~110℃), a simple software compensation algorithm can be designed based on the temperature drift coefficient (-1.8%/℃) to further improve detection accuracy.

With core competitive advantages of "high sensitivity, low offset, strong adaptability, and stable performance over a wide temperature range", the NHE312 Hall element perfectly addresses pain points such as weak signals, high interference, and difficult integration in low magnetic field detection scenarios. Whether for brushless motors, position sensors, current detection, or magnetic flux collection, it provides accurate and reliable sensing solutions. Additionally, it features easy integration and strong compliance, making it the preferred Hall element for industrial electronics, consumer electronics, automotive electronics, and other fields.
