4 Performance Comparison

This section explains the details of the test setup used for each of the devices as well as the resulting data to provide a suitable comparison of performance and repeatability in detection. For all tests explained in the ensuing sections, the same cylindrical magnet is used leveraging the same approach to the sensor/switch.

Another set of tests for these 3 devices which can be important to product designers is tamper susceptibility. In the case of door and window sensors, it goes without saying that the devices must not be susceptible to tampering through the introduction of an external magnet into the detection field of the sensor. This condition lends itself to a final set of tests to determine how efficient each device is at resisting tampering attempts. The test environment is set up per the following descriptions.
