S1 FORM B SERIES  

UL APPROVED* MINIATURE SIL REED RELAY WITH FORM B (N/C) CONTACTS  

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

relay for applications where space saving is a prime consideration, with  

normally closed contacts.  

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  

• 1.5kV Isolation Voltage across contacts  

• 1.3A carry current  

• Up to 1000V switching voltage  

Custom versions can be made for particular applications.  

Please contact Sensata with your requirements.
