S8 RELAY SERIES  

MINIATURE HIGH VOLTAGE RELAY  

The S8 series is a miniature high voltage reed relay for applications  

where space saving is a prime consideration.  

The coil pins are positioned near the center of the relay while the  

contact pins are near the ends to give improved isolation between the  

High Voltage contacts and the low voltage coil.  

Features  

• Space saving package  

• Isolation Voltage across contacts 4kV or 5kV  

(dependent on coil voltage)  

• Isolation Voltage 7kV contact to coil  

• 2.5A carry current  

• Up to 1000V switching voltage
