Datasheet

## **FORCE GUIDED RELAY SRS2** 

## GENERAL PURPOSE RELAYS 

## **INTRODUCTION** 

TE Connectivity (TE)’s SRS2 is a force guided relay (IEC/EN61810-3 type A) for safety applications with limited space. The just 210 mW coil power consumption helps allow a dense arrangement in hot environments. The NO contact can switch 2 A/ 250 VAC or 6 A/ 24 VAC/DC and is linked to a monitoring NC contact with a diagnostic coverage of 99% (IEC 61508-2). The relay can be mounted upright or horizontal. 

## FEATURES 

- Slim 2 pole relay with force guided relay according to type A of IEC/EN 61810-3 (EN50205) 

- 1 form A (NO) + 1 form B (NC) contacts 

- Small size (28 x 6 x 15.5) mm 

- Polarized magnet system with small coil power consumption (210 mW) 

- Reinforced insulation between NO and NC–circuit and between NO and relay coil
