S SERIES  

HIGH VOLTAGE RELAYS  

The S series relay was developed for the high voltage ATE market, where  

printed circuit board space is at a premium.  

The S series high voltage relay offers a 3kV or 5kV* isolation performance  

in a 30mm package.  

Low contact resistance, through the use of Rhodium contact reed  

switches, makes the S series suitable for many high voltage  

applications at DC and low frequency, where performance and reliability  

are paramount.  

Features  

• Compact footprint  

• Designed specifically for High Voltage ATE  

• Rhodium contacts for Low Contact Resistance  

• 3kV or 5kV* Isolation between contacts and 5kV isolation between  

contacts and coil  

• Excellent lifetime characteristics
