Abstract
Non-contact positions sensors are desirable because they have lower failure rates than traditional potentiometers. However, using a Hall Effect sensor as a non-contact position sensor requires a particular input polarity. In an embodiment, a polarity insensitive Hall Effect sensor includes conversion sensors configured to produce outputs responsive to an input. The sensor also includes a semiconductor rectifier arranged to power a first conversion sensor and a second conversion sensor with a given polarity regardless of whether the input has a positive or negative polarity. The sensor also includes a semiconductor multiplexer circuit arranged to direct the first output to a common output port if the input has a positive polarity and direct the second output to the common output port if the input has a negative polarity. The polarity insensitive Hall Effect sensor provides an output representing a position without requiring a input polarity.
