One of the most critical factors in choosing a reed switch sensor is its magnetic sensitivity. This is the amount of magnetic force required to actuate the switch. Magnetic sensitivity is typically measured in ampere-turns (AT). Depending on your application, you may need a sensor with higher or lower sensitivity. For instance, a higher sensitivity reed switch (10-30 AT) might be necessary for low-power applications, while a lower sensitivity switch (50-100 AT) could be suitable for applications where a stronger magnetic field is available.

2. Contact Configuration

Reed switch sensors come in various contact configurations, including:

Form A (Normally Open): The switch is open when no magnetic field is present and closes when exposed to a magnetic field.

Form B (Normally Closed): The switch is closed when no magnetic field is present and opens when exposed to a magnetic field.

Form C (Changeover): This configuration has a common contact that switches between normally open and normally closed contacts.

Choosing the correct contact configuration depends on your specific application needs. For example, Form A switches are commonly used in alarm systems, while Form C switches are often found in more complex circuitry requiring dual state operation.
