Magnetic Contact Switch Sensor for Arduino

• Magnetic Contact Switch Sensor for Arduino
• Color: black
• Offers compact structure and small weight
• Provides long service life
• Operating Voltage: 0 ~ 100 V
• Operating Principle: Magnetic sensor

The Magnetic Contact Switch Sensor for Arduino consists of two magnetic reeds sealed in a plastic case. The two magnetic reeds are overlapped but there is a small gap between them.

When a suitable external magnetic field comes within 2 cm, the two magnetic reeds will contact and conduct, thereby sensing the change in the position of the object.
