Additional Details

The EM-1712 typically operates with a supply voltage range of 2.4 V to 5.5 V and has a typical operating current of around 3mA. It's available in a small SOT-23 or similar surface-mount package. The output switches when the magnetic field strength exceeds a certain threshold (operate point) and switches back when the field strength falls below another threshold (release point). The specific values for operate and release points depend on the specific configuration of the sensor. It is RoHS compliant.
