The Cynergy3 S8 series miniature high voltage reed relay is perfect for applications where space saving is a prime consideration. To give improved isolation between the high voltage contacts and the low voltage coil S8 miniature reed relays have the coil pins positioned near the centre of the relay while the contact pins are near the ends.

Space saving package
Isolation Voltage across contacts 4kV or 5kV (dependant on coil voltage)
Isolation Voltage 7kV contact to coil
2.5A carry current

If you're looking for a reliable reed relay but have limited space on your PCB (printed circuit board), go for this miniature option from Sensata Cynergy3. It has rhodium contacts that ensure a strong connection thanks to their low-contact resistance. The design of this relay, with coil pins at the centre and contact pins at the end, improves isolation between the two, despite the unit's compact size. Choose it for applications where both space efficiency and reliability are important, such as cardiac defibrillators and test equipment.

• Durable rhodium contacts give a long life cycle of ten million wet and one billion dry operations
• Large operating temperature range (-40°C to +85°C) makes it suitable for harsher environments
• Small size means a fast operating time of 1ms (millisecond) including bounce

Despite its compact dimensions, this relay has a high maximum switching voltage of 1000V.

The reed switch is configured as normally open – that means the contacts are separated (or open) unless the electromagnetic coil is powered on.
