This Product Selection Guide contains information to help select products in the Magnetic Sensors - Switches (Solid State) category on DigiKey.com
Products in this family use solid-state technology for detecting the presence of a magnetic field in excess of some specific magnitude and/or sign, and provide a two-state output indicating the presence or absence of such a field. They are distinct from reed switches, which provide a similar function through the use of moving mechanical parts, as well as from linear or compass-type solid-state devices which provide a variable output indicative of the strength and/or orientation of an applied magnetic field.
SelectionCharacteristics
Specifications to determine which magnetic switch is right for your application.
Function: Identifies what type of switch it is, such as bipolar, omnipolar, etc.
Technology: How the circuit is setup to function, such as hall effect, magnetoresistive, etc.
Polarization: Identifies the polarity of the magnet.
Sensing Range: Physical distance between the trip and release points.
Test Condition: The temperature or range of temperatures the manufacturer tested the switch in.
Voltage - Supply: Typically represented by a range, this indicates the low and high voltage limits which one can expect standard operation. Voltages outside this range may damage the device and other system components.
Current - Supply (Max): This represents the maximum current to which a device will meet its given specifications. Exceeding this current may damage the device and/or other system components.
Current - Output (Max): The maximum amount of current that can be output by the device.
Output Type: Indicates the type of electrical signal the device provides, such as digital, analog voltage, etc.
Features: These are different capabilities or properties of the device such as amplified output, programmable, sleep mode, etc.
Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.
Mounting Type: Indicates how the device is attached.
Supplier Device Package: This is what the manufacturer calls the package of this device. They are manufacturer specific. It is typically best to use the actual dimensions from the datasheets rather than to go by this terminology when designing your circuit.
Package/Case: Indicates the type of protective case used on an electronic component to allow easy handling, installation, and protection. This selection was determined to be the closest industry standard applicable to the suppliers device packaging. Typically it is best to check the actual dimensions from the datasheet rather than depend on this terminology when designing your circuit.
