M52EXSV

## Saft M 52 EX SV 2 cell Primary Li-MnO 

3 V lithium manganese dioxide C-size spiral cell certified for ATEX applications 

Saft’s M 52 EX SV cell is ideally suited for applications requiring high energy and long operating life, with stable voltage under high discharge in - 40°C / + 72°C environment. The cell is certified according to ATEX and IECEx for use in potentially explosive atmospheres. 

## 

- High drain / high pulse capability 

- High voltage response, stable during most of the lifetime of the application even after long dormant periods 

- High capacity and very high pulse capability 

- Low self-discharge compatible with long operating life (less than 1% after 1 year of storage at + 20°C) 

- 

- Superior resistance to corrosion 

- ■ Low magnetic signature 

## Key features 

- Spiral construction 

- Hermetic construction with glass-to-metal seal 

- Stainless steel container

- (1) Dependent upon current drain, temperature and cut-off. 

## Typical applications 

   - (2) Limitation of the max. current to a lower level, e.g. by a series resistor, may be necessary depending on the electrical properties of the device and the desired level of protection (ia, ib, ic) and the explosion group (IIA, IIB, IIC). 

- Smart gas meters 

   - (3) To maintain cell heating within safe limits. Battery packs may imply lower level of maximum current and may request specific thermal protection. Consult Saft. 

- Gas and oil tank level monitoring 

   - (4) Long time storage at high temperature may affect performances. Consult Saft. 

- Leak detectors 

   - (5) 

- Portable gas detectors 

(6) During the 3 mΩ short-circuit test according to IEC 60079-11. 

- Petrochemical facilities
