52mm 3 Pin Reed Switch Golden Contact Magnetic Sensor SPDT NO NC Glass Type Magnetic Switch (Reed Switch Sensor)
The 52mm 3 pin reed switch with golden contact is a magnetic sensor designed for detecting magnetic fields and providing switching output in NO NC configurations. It uses a glass sealed structure with gold plated contacts for improved conductivity and long life operation.
Key Features -
- Magnetic field operated reed switch sensor
- 3 pin SPDT configuration NO NC switching

- Passive device with zero power consumption
- Glass encapsulated sealed construction
- High reliability for industrial applications
Specifications -
- Sensor type - reed switch magnetic sensor
- Contact type - SPDT normally open normally closed
- Total length - approx 52mm
- Switching voltage - up to approx 250V AC DC
- Switching current - up to approx 1A max
- Contact material - gold plated contacts
- Output type - digital switching output
Applications -
- Door and window open close detection
- Security alarm systems
- Position and limit sensing
- Industrial automation systems
- Level sensing and float switches
Pinout Configuration -
- Pin 1 - common terminal
- Pin 2 - normally open contact
- Pin 3 - normally closed contact
Working Principle -
The reed switch operates using ferromagnetic contacts sealed inside a glass tube. When a magnetic field is applied the internal reed moves to change contact state between normally open and normally closed terminals. When the magnetic field is removed the contacts return to original state enabling reliable non contact switching.
