2Dex™ Hall Sensor Technology
2Dex™ Hall Sensor Technology Features
- Sensor technology used in FP Series probes for the F71/F41 teslameters
- Under development for release as stand-alone sensors for higher volume applications
- Plug-and-play versions are now available for direct connection to F71/F41 teslameters
- Improved sensor ruggedness
- Active area indicators where possible
Multiple package types
Due to the directional nature of magnetic fields, the positioning and orientation of the sensor are critical for accurate measurements. 2Dex sensors are offered in a range of packages and orientations to simplify the process of locating the sensor in just the right location.
Products featuring 2Dex sensor technology
2Dex sensors for DIY instrumentation (FUTURE RELEASE)
2Dex plug-and-play sensors connect directly to the F71/F41 teslameters, giving you the installation flexibility of a Hall sensor with the measurement simplicity and performance of a teslameter/probe combination.
Smaller active areas
2Dex Hall sensors have significantly smaller active areas than previous generation products. This results in improved spatial resolution and reduced signal averaging, useful when measuring fields close to a source where field gradients can be extreme.
Better 3-axis measurements
2Dex 3-axis magnetic sensors have been designed to maximize orthogonality between x, y, and z sensor elements, resulting in more accurate vector magnitude measurements when field direction is unknown or changing.
Suitable for extreme environments
Materials in 2Dex sensors have been selected to work at both cryogenic and elevated temperatures, resulting in sensors with extremely wide operating temperature ranges. These sensors have also been characterized over their full operating temperature range for variables such as sensitivity, resistance, offset voltages, and quantum oscillations. This provides sensors with predictable behavior for various scenarios, and when they are paired with an F71 or F41 teslameter, automatic compensation for these variables result in highly accurate measurements — even in extreme environments.
The 2DEG material used in these sensors is inherently resilient to radiation — so much so that the same material used in 2Dex sensors has been used in satellite solar panels.
(New package coming soon) Based on the popular SD package for cryogenic temperature sensors, the hermetic construction of the SH package makes it suitable for extreme research environments, including UHV scenarios.
Until this package is released, please contact Lake Shore to discuss how customization of our existing sensors can achieve your required level of vacuum suitability.
