Which configuration is NOT a typical package type for Hall effect sensors?

The configuration that is not a typical package type for Hall effect sensors is the transformer. Hall effect sensors are primarily designed for detecting magnetic fields and are commonly found in configurations such as plunger, vane, and cylinder.

Each of these configurations serves specific applications. For instance, plunger-type sensors can be used for proximity sensing or limit detection where a moving part engages the sensor. Vane-type sensors are often employed in applications such as speed sensing or position detection, where a rotating element can disrupt the magnetic field. Cylinder configurations typically place the sensor within a cylindrical housing, suitable for various environmental conditions while facilitating specific mounting options.

In contrast, a transformer configuration is designed for electromagnetic induction rather than magnetic field detection, which is the primary function of Hall effect sensors. Therefore, transformers do not apply to the typical configurations used for Hall effect sensors, making this the correct choice.
