These high voltage PCB and panel mount reed relays have high isolation voltages of up to 15kV. Applications include test equipment and high voltage power supplies. All models are highly reliable and are of extremely good quality.

High power switching
Through hole PCB & panel mount or flying lead versions
15kV high isolation versions available
Tungsten contacts enable high voltage switching

This reed relay from Sensata Cynergy3 uses a high-vacuum reed switch and has been tested to a life of one million cycles so reliability is assured. Robust tungsten contacts mean it can switch at very high voltages of up to 7000V for both AC and DC. You can also count on a very fast switching speed of 3ms (milliseconds) including bounce. This reed relay is ideal for applications where consistency and speed of performance is vital, such as cardiac defibrillators or sensitive laboratory test equipment.

• Wide operating temperature range of -20°C to +70°C for use in harsh environments
• Robust tungsten for exceptional hardness and resistance to wear
• Hermetically sealed to protect against contaminants and corrosion

This model is PCB (printed circuit board) mounted using the through-hole method, which makes it reliably secure.

SPNO stands for single pole, normally open and is the most common configuration for reed switches. It means that the contacts are normally open, so the circuit is closed until the electromagnet is switched on.
