Assemtech SPNO PCB Reed Switch 3 A 400 V ac/dc GC3817 (60-70AT)

Assemtech GC3817 (60-70AT) SPNO PCB Reed Switch is a precision electronic component designed for reliable switching applications in electrical and automation systems. It is hermetically sealed within a gas-filled glass envelope, protecting the magnetic reeds and ensuring stable operation over time. The switch features single pole, single throw normally open contacts with rhodium plating for excellent contact resistance and longevity.

With a maximum switching current of 3 A and switching power of 60 W, this reed switch is suitable for controlling moderate load electrical circuits at 400 V ac/dc voltage. The wire terminals and PCB mount type design facilitate easy integration on electronic circuit boards.

The operating temperature range from -40°C to 125°C makes it suitable for demanding industrial and HVAC environments where temperature extremes occur. The magnetic actuation allows it to be triggered by an electromagnet or permanent magnet, with fast response times including a 0.1 ms maximum release time and 0.5 ms operating time including bounce.

The AT value range of 60 to 70 AT provides variable magnetic sensitivity to tailor the switch actuation based on the application's magnetic field strength. This product belongs to the GC series and complies with ISO standards, ensuring quality and performance consistency.
