In industrial applications, they are intended for use in position encoders and commutation of brushless motors and fans.

The development of these devices addresses a growing market demand for high-sensitivity InSb Hall sensors in the industry-standard 4-pin SOT23-4 and SIP-4 packages.

The AHE300 InSb sensor supports Hall output voltage (VH) classifications C-G, which range from 168mV to 370mV. The AHE10x sensors support classifications C-H and deliver VH up to 415mV.

The ultra-high sensitivity of these sensors allows them to operate reliably even in the presence of weak magnetic fields across a broad range of applications and, in addition, the low offset voltage (5mV to 7mV) of these sensors achieves the level of resolution required to deliver high-accuracy detection capabilities.

The AHE300 sensor operates in the -40°C to +110°C temperatures range, is housed in a SIP-4 (Type MA) package.

The AHE10x devices operate over a wider temperature range (-40°C to +125°C), making them sufficiently robust for use in harsh thermal environments. For application flexibility, they are supplied in SOT23-4 packaging with various height options (A, B, C).
