Below you will find 2 different versions of our 2 output Hall Switch Speed and Direction sensor. The HSCD triggers only from the S pole of a magnet and has a high enough operate point that it ignores stray fields. The MRCD is a very sensitive Magneto-Resistive Speed / Direction Switch that triggers from either pole of a magnet. Use this version with our Multi-Pole Magnet Strip Tape, when you don't know the magnet pole, or desire a farther trigger gap. Click on the box that best fits your needs, and you will be brought to the electrical option choice page.
