22mm - Reed Switch/Sensor (Magnetic Switch) -Gold Platted - NO (Normally Open)

22mm Gold Plated Normally Open (NO) Reed Switch Sensor

The 22mm Gold Plated Normally Open (NO) Reed Switch Sensor functions as a magnetic switch. It is engineered for precise magnetic field detection. Operation initiates when an external magnetic field causes the internal metal reeds to close. The reeds are hermetically sealed within a tubular glass envelope. This configuration ensures the circuit remains open until a magnetic field is detected. Gold-plated pins provide enhanced conductivity and corrosion resistance. Its 22mm length facilitates integration into diverse electronic systems. This sensor is suitable for applications requiring responsive magnetic sensing. It offers a functional design for both prototyping and professional implementations.

Frequently Asked Questions:

Q: What is a Normally Open (NO) reed switch?
A: A Normally Open (NO) reed switch maintains an open circuit state until a magnetic field is applied, causing the internal reeds to close and complete the circuit.

Q: What are the benefits of gold-plated pins on a reed switch?
A: Gold-plated pins enhance electrical conductivity and provide increased resistance to corrosion, contributing to the sensor's operational lifespan.

Q: How does a reed switch detect a magnetic field?
A: A reed switch detects a magnetic field when the field magnetizes and attracts two ferromagnetic reeds, causing them to flex and make electrical contact.
