Additional Details:

The SS411A-S operates on a supply voltage range that should be consulted in the datasheet. The sensor has a defined operate and release point for the magnetic field strength, also specified in the datasheet. Hysteresis (the difference between the operate and release points) ensures clean switching and prevents false triggering. The sensor is typically packaged in a small SIP (Single In-line Package). Refer to the Honeywell datasheet for detailed electrical and mechanical specifications, as well as application notes. Proper magnet selection and placement are crucial for optimal performance.
