52mm 3 Pin Reed Switch Silver Contact Magnetic Sensor SPDT NO NC Glass Type Magnetic Switch (Reed Switch Sensor)

The 52mm 3 pin reed switch with silver contact is a magnetic sensor designed to detect magnetic fields and provide switching output in normally open and normally closed configurations. It uses a glass sealed structure with silver contacts for stable performance and cost effective operation.

Key Features -

• Magnetic field operated reed switch sensor
• 3 pin SPDT configuration normally open normally closed
• Silver contact for reliable switching performance
• Passive device with zero power consumption
• Glass encapsulated sealed construction
• Suitable for general purpose sensing 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 - silver contact
• 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 reeds move and change the 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.
