## **SCHRACK FORCE GUIDED RELAYS SR6 NEXT GENERATION (SR6NG)** 

GENERAL PURPOSE RELAYS 

FORCE GUIDED RELAYS 

## **INTRODUCTION** 

TE Connectivity (TE)’s SR6nG is a fully compatible successor of TE’s force guided relay series SR6A/B/C/V/D/M. With its force guided contacts the state of a contact can be monitored with a diagnostic coverage of 99% (IEC 61508-2) which makes the SR6nG ideal to design safety circuits. The Minimum contact load of 5V / 1mA allows direct monitoring through controller input. A more sensitive monostable magnetic coil system reduces heat generation. The relay height of 15.7mm fits best in 22.5mm DIN rail housings. 

## FEATURES 

- Monostable relay with 6 (4) force guided contacts acc. to IEC 61810-3 

- Circuits of up to 400V can be connected. Contacts can switch up to 8A or 2200VA. 

- Creepage and clearance distances allow reinforced isolation (IEC EN 62477) not just between coil and contacts but also between all contacts. 

- 6 pole version with 3 different contact sets (3NO/3NC; 4NO/2NC; 5NO/1NC) 

## APPLICATIONS 

- Safety Relay modules, 

- Safety Controllers, PLC’s 

- Machines, Presses, Robots, 

- Emergency shut-off, Light barriers 

- Elevator and escalator safety control 

- • Railway Level crossings, Signaling 

## APPROVALS 

   - VDE CERT. NO. 40055844 

- Sensitive coil of 700mW allows use at 85°C under IEC 61810 conditions 

- Special 4 pole version offers >15mm isolation between contacts and just 550mW coil power 

- TUV 968/FSP 2469.00/22 

- UL E214025 VOL.9 SEC.6 

- CCC 2022000303000046
