Magnetic position sensors use the measured magnetic field to detect the position or presence of a magnet. Common examples are door/window open or closed detection and wheel revolution counting as in a gas or electric meter. Tampering means using second magnet to defeat or fool the position sensor. In today's security conscious world inclusion of tamper detection is becoming more and more a requirement. Attendees of this session will learn about:

1.) Requirements related to tamper detection in security applications and electronic meters (wheel revolution counting)
2.) Strategies for tamper detection and adding tamper detection with minimal cost and power penalty
3.) Case studies related to tamper detection for security applications and electronic meters
