S1 RELAY SERIES  

UL APPROVED* MINIATURE HIGH VOLTAGE RELAY  

The S1 series is a miniature high voltage single-in-line 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  

• Single-in-line package  

• 4kV Isolation Voltage across contacts  

• Isolation Voltage 5kV contact to coil  

• 2.5A carry current  

• Up to 350V switching voltage  

Please refer to this document for circuit design notes:  

Custom versions can be made for particular applications.  

Please contact Sensata with your requirements.  

*Consult factory for UL ratings  

These products have been UL approved for use as per pollution degree  

2 classification.
