Digital Hall Effect Sensor: Magnetism Sensor

This digital Hall Effect Sensor / Magnetism Sensor is useful for telling whether a magnet is nearby or not. This sensor's behavior is similar to a reed switch, except the output toggles when a magnet is nearby instead of just staying steady on.

If you are looking for an analog hall effect sensor that varies the voltage with proximity of a magnet, check out this Analog Hall Effect Sensor.

Specifications:

• Latching Digital Hall Effect Sensor / Magnetism Sensor
• Digital Output
• Supply Voltage: 3.5V - 24V DC
• Max Supply Current: 5mA
• Output toggles when a north followed by south pole of a magnet are nearby. Note: Requires both a north and south pole to function. If mounting on a wheel, you will mount 2 magnets on the wheel diametrically opposite from each other so that the north and south pole both pass the sensor and toggle the input high and low. See datasheet for more details.
