This Product Selection Guide contains information to help select products in the Pushbutton Switches - Hall Effect category on DigiKey.com
Pushbutton Switches - Hall Effect, are pushbutton switches that use an electronic circuit, sensing changes in magnetic field position to change operational states. Without any mechanical parts making contact, they can achieve significantly longer operational life cycles and environmental protections while reducing space requirements and operational effort.
SelectionCharacteristics
Switch Function: Refers to the specific operation or behavior of a switch, indicating the primary purpose or mode of operation. For more information please see Switch Basics, Examples of Pole and Throw.
Supply Voltage: 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.
Supply Current: Characterizes the amount of supply current required for device operation.
Voltage - Output (Max): Indicates the maximum output voltage that a device is capable of producing or accommodating, subject to specified limitations or constraints.
Current - Output (Max): Indicates the maximum output current that a device is capable of producing or accommodating, subject to specified limitations or constraints.
Actuator Type: The specific design or style of the mechanism used to change the switch position.
Actuator Color: Refers to the specific color of the actuator or cap of a switch.
Ingress Protection:
IP (Ingress Protection) Ratings (IP20, IP65, IP67, etc.) - Define how likely it is that water and dirt will get into the system. The first number is for dirt and solid contaminants and the second number is for water.
IP Ratings
| Protection Level | Solids | Liquids |
|---|---|---|
| 1 | Protected against solids larger than 50mm. | Protected against vertically falling drops of water. Limited Ingress permitted. |
| 2 | Protected against solids larger than 12.5mm. | Protected against vertically falling drops of water with the enclosure tilted up to 15 degrees from vertical. Limited ingress permitted. |
| 3 | Protected against solids larger than 2.5mm. | Protected against spraying water up to 60 degrees from vertical. Limited ingress permitted for 3 minutes. |
| 4 | Protected against solids larger than 1mm. | Protected against water splashing from any direction. Limited ingress permitted. |
| 5 | Protected against dust. Limited ingress of dust permitted. | Will not affect the operation of equipment 2-8 hours. Protected against jets of water. Limited ingress permitted. |
| 6 | Dust tight. No ingress of dust 2-8 hours. | Protected against powerful jets of water. Limited ingress permitted. |
| 7 | ______________________ | Protected against the effects of immersion in 15cm-1m for 30 minutes. |
| 8 | ______________________ | Continuous immersion in water up to 3m for long periods of time. |
| 9 | ______________________ | Protected against high-pressure jets of hot water. (30 seconds) |
| 9K | ______________________ | Protected against high-pressure jets of hot water. (2 minutes) |
Termination Style: Selection of termination style used to connect the device to a system, such as PC pins or wire leads.
Mounting Type: Indicates how the device is attached.
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.
