Specifications: The AHW-101A is a surface-mount InSb Hall element in a reverse-mount SOT package. It offers a very high sensitivity with a Hall voltage range of 168-516mV at 20mA input. Its input and output resistances are low and symmetrical (240-550Ω), contributing to fast response. The offset voltage is tightly controlled at ±5mV. It is rated for operation from -40°C to 125°C. Application Scenarios: Its high output and SMT compatibility make it ideal for automated assembly in high-volume applications. It is widely used in brushless DC (BLDC) motor drives for high-efficiency appliances and cooling fans, providing precise commutation. It's also excellent for high-current shunt-based current sensors in power supplies and motor controllers, where its large signal minimizes amplification needs and improves signal integrity.

Specifications: The AHW-101A-4T is a variant of the high-sensitivity AHW-101A, packaged in a right-angle SOT configuration. It maintains the same core electrical specs: 20mA input, 168-516mV output, 240-550Ω resistances, and ±5mV offset over -40°C to 125°C. The right-angle package alters the PCB mounting orientation. Application Scenarios: This package is designed for space-constrained designs where the sensor needs to be mounted perpendicular to the PCB plane. It is ideal for sensing the edge of a rotating magnet in compact gear-tooth or vane sensors, for integration into the sides of slim modules (like memory card readers with slot-in detection), or anywhere the magnetic field is parallel to the PCB, requiring a 90-degree sensing axis.

Specifications: The AHW-102A-FU is a variant of the AHW-102A InSb Hall element, sharing all its key electrical parameters: 20mA input, 196-465mV Hall voltage, 250-550Ω resistance, ±7mV offset, and a -40°C to 125°C temperature rating. Application Scenarios: Likely tailored for specific performance bins or customer requirements, this model is deployed in applications demanding the consistent high-output performance of the 102A series. It is suitable for precision torque sensing in power tools, RPM sensing in high-speed machinery, and feedback systems in servo amplifiers, where the "FU" designation may indicate enhanced consistency or screening for critical parameters.

Specifications: The AHW-105A is an InSb Hall element in an Ultra-Thin SOT package, with a height of only 0.55mm. It operates at 20mA, delivering a Hall voltage of 168-274mV. It maintains the characteristic low InSb resistance (250-550Ω) and a ±7mV offset. It is rated for -40°C to 125°C. Application Scenarios: The ultra-low profile is its defining feature. It is perfect for integration into extremely thin devices like smartphones, tablets, and ultrabooks for flip cover/hallpixel detection. It is also ideal for wafer-thin modules in credit card-sized devices, wearable health monitors, and flexible/printed electronics where z-height is a critical constraint, without sacrificing the inherent sensitivity of InSb technology.

Specifications: The AHW-322B is a high-performance InSb (Indium Antimonide) Hall effect element in a compact SIP (Single In-line Package). Engineered for extreme environments, it operates from -55°C to 125°C. It features a maximum input current of 20mA and generates a substantial Hall voltage ranging from 168mV to 465mV, indicating very high sensitivity. Its input and output resistances are symmetrical, ranging from 240Ω to 550Ω, and it has a controlled offset voltage of ±7mV. This combination makes it exceptionally responsive to magnetic fields. Application Scenarios: This element is ideal for precision sensing in aerospace, defense, and automotive under-hood applications where wide temperature stability is critical. It is perfect for high-resolution angular position sensors (e.g., in throttle or pedal position sensing), contactless current measurement in harsh environments, and as the core sensor in scientific instruments and military-grade equipment requiring reliable performance from arctic to desert conditions.

Specifications: The ANHE313 is a rugged, wide-temperature InSb Hall element in a SIP package, sharing identical electrical and mechanical specifications with the AHW-322B. It delivers a high Hall voltage output (168-465mV) with 20mA drive, features low and balanced 240-550Ω input/output resistance, and maintains a ±7mV offset across an operational span of -55°C to 125°C. Application Scenarios: As a functional equivalent to AHW-322B, it is designed for demanding applications requiring a robust, through-hole sensor. Typical uses include servo feedback systems in industrial robotics, position sensing in off-road vehicle transmissions, and environmental monitoring equipment deployed in remote, climatically challenging locations. It serves as a reliable, high-sensitivity alternative for system designers seeking a second-source component.
