Description

This Hall Effect Switch Sensor is ideal for detecting the presence of ferrous or magnetic objects to determine rotational speed, the presence or absence of parts, or position limits.

The output for this sensor is an open collector type. This means it is like a switch that connects the signal wire to ground (0V) when activated, and leaves it open circuit when not active. When you connect to a microcontroller to detect this changing you need to connect a pull-up resistor (1K-10K) between the signal wire and the power supply.
