Hall Effect Limit Switch

A hall effect switch will turn on in the presence of south magnetic field on its face or north magnetic field on the opposite side.

Hall effect limit switch.

Edwin hall for whom it is named back in the late 1870 s. Self centering device with no mechanical switch components to worry about degradation over time. Contactless bounce free hall effect technology provides precision control and long life operation. It will turn off when the magnet is removed.

For clarity the original effect is sometimes called the ordinary hall effect to distinguish it from other hall effects which have. The effect of generating a measurable voltage by using magnetic fields was discovered by dr. I decided to pursue a limit switch based upon a hall effect sensor and the following is what i learned along the way. Miniature hall effect switch stick.

You can disconnect the hall effect switch from pin 2 of the arduino or you can just leave it alone and ignore it the sketch will only be looking at the switch on pin 3. It will turn off if the north pole is applied to the face or the power is turned off. It was discovered by edwin hall in 1879.

Homing sensor arduino sketch. The hardware setup for this experiment is identical to the limit switch demo except you only need one hall effect switch. Miniature low voltage thumb controlled 4 way hall effect switch. Mini 3 way air switch general purpose miniature rotary ii 6 position selector 300 series cartridge 400 series cartridge 4 way 4 series 45 series rugged industrial ergo low stress ltv light touch actuation general purpose.

The heart of every micro switch hall effect de vice is the integrated circuit chip that contains the hall element and the signal conditioning electronics.
