Hotel Card Readers Use Reed Sensors for Detection

Features

• Magnet and Reed Sensor are isolated and have no physical contact by typically having the magnet mounted to a mechanical arm, and the Reed Sensor mounted and positioned usually on a PCB to accurately pick up the movement of the magnetic field from the magnet on the arm.
• The reed switch used in the Reed Sensor is hermetically sealed and is therefore not sensitive to wet, dirty, dusty environments.
• The magnet is not affected by its environment
• Tens of millions of reliable operations.
• Surface mount and through hole packages available
• Contacts dynamically tested
