## **SCHRACK SLIMLINE PCB RELAY SNRII** 

## GENERAL PURPOSE RELAYS PCB RELAYS 

## **INTRODUCTION** 

TE Connectivity (TE)’s SCHRACK SNRII slim PCB relay is a compact 5 mm-wide solution designed for PCB mounting, available in vertical, flat pack, and DIN rail socket-compatible versions with reinforced coil terminals. Featuring a 6A single changeover (CO) contact, the SNRII serves as a direct replacement for the legacy SNR (V23092 Series), offering full compatibility with existing socket solutions. It delivers enhanced performance with improved vibration resistance and a longer mechanical and electrical lifecycle, making it highly suitable for space-constrained applications that demand reliability and durability. 

## FEATURES 

- 1 pole 6A, 1 form C (CO) 

- Ambient temperature up to 105 °C 

- Only 5 mm wide 

- Flat pack version available 

- Sensitive coil 170 mW 

- Reinforced insulation (protection class II) 

- Reinforced coil pins for DIN-rail socket 

- Allows high function - packaging density 

## APPLICATIONS 

- Automation 

- Motion and drives 

- Control cabinet builders 

- Machine manufacturers 

- Interface technology 

## APPROVALS 

- VDE: 40060851 

- UL: E214025
