41. Door Reed Switch Selection
Jennifer is designing an enclosure door detection circuit for an industrial device.
A magnet will be mounted on the door, and a reed switch will be mounted on the PCB to detect door open/close status.
The switch will work in a 24V DC sensing circuit with very low current.
Help her select a suitable reed switch from DigiKey.
Make sure it supports 24V DC sensing, has suitable magnetic sensitivity, and works reliably over temperature.
