14mm 2 Pin Reed Switch Magnetic Sensor Normally Open Glass Type Mini Reed Switch (14mm Reed Switch)

The 14mm reed switch is a compact magnetic sensor designed for detecting magnetic fields and providing a simple switching output. It consists of sealed ferromagnetic contacts inside a glass tube and operates without external power, making it suitable for low power and embedded systems.

Key Features -

• Miniature 14mm glass reed switch
• 2 pin normally open contact type
• Fast switching response to magnetic field
• Zero power consumption passive device
• Hermetically sealed for long life
• High sensitivity to magnetic fields

Specifications -

• Sensor type - magnetic reed switch
• Contact type - normally open SPST
• Length - approx 14mm glass body
• Switching voltage - up to approx 100V DC typical
• Switching current - up to approx 0.5A max
• Contact resistance - low resistance when closed
• Operating mode - magnetic proximity switching

Applications -

• Door and window sensing systems
• Position detection in small devices
• Counting and speed sensing
• Security alarm circuits
• Embedded electronics and IoT devices

Pinout Configuration -

• Pin 1 - reed contact terminal
• Pin 2 - reed contact terminal

Working Principle -

The reed switch contains two ferromagnetic contacts sealed inside a glass tube. When a magnetic field is applied the contacts attract and close the circuit and when the magnetic field is removed the contacts return to open state. This enables reliable non contact switching operation.
