Reed Magnetic Switch

Description

• Contact Form: Typically SPST (Single Pole Single Throw, normally open) or SPDT (Single Pole Double Throw, changeover). 
• Operating Principle: Magnetic actuation, with contacts closing in the presence of a magnetic field. 
• Contact Material: Ferromagnetic reeds sealed in a glass capsule. 
• Switching Capacity:
  • Voltage: Can range from low voltage to high voltage (e.g., 10,000 VDC). 
  • Current: Can range from low current to high current (e.g., 15 Amps, pulsed to 30 Amps). 
  • Power: Can range from milliwatts to watts, depending on the specific switch. 
• Contact Resistance: Typically low to ensure efficient conductivity. 
• Sensitivity: Measured in ampere-turns (AT), with lower numbers indicating greater sensitivity. 
• Response Time: Typically fast, allowing for quick switching. 
• Environmental: Hermetically sealed, making them suitable for various environments, including those with temperature and humidity variations.
