Product Overview

The Saft M 52 EX SV is a compact, high‑reliability Lithium Manganese Dioxide (Li‑MnO₂) primary cell engineered specifically for explosive atmospheres, hazardous industrial zones, and intrinsically safe (IS) equipment. With its ATEX/IECEx‑compliant construction, stable 3.0V output, and strong pulse capability, the M 52 EX SV is widely deployed in oil & gas, petrochemical, mining, metering, and industrial IoT systems that require long‑life, maintenance‑free power under strict safety constraints.

Engineered for Hazardous Environments

The defining feature of the M 52 EX SV is its EX‑rated safety design, making it suitable for equipment operating in environments with flammable gases, vapors, or dust. Its construction is optimized to prevent ignition sources while maintaining long‑term electrical performance.

Key safety advantages include:

• Compliance with ATEX, IECEx, and other hazardous‑area standards

• Intrinsically safe (IS) design for Zone 0/Zone 1 equipment

• Non‑pressurized, non‑flammable Li‑MnO₂ chemistry

• Hermetically sealed stainless‑steel construction

• High mechanical robustness for vibration, shock, and thermal stress

This makes the M 52 EX SV a trusted choice for OEMs designing certified industrial devices.

Li‑MnO₂ Chemistry and Performance Benefits

The M 52 EX SV uses Li‑MnO₂ chemistry, which provides a balanced performance profile ideal for moderate‑drain and pulse‑driven applications:

• High pulse capability without external capacitors

• Stable 3.0V output across most of the discharge curve

• Excellent intrinsic safety due to the stable Li‑MnO₂ system

• Good performance at moderate to high discharge rates

• Wide operating temperature range, typically −40°C to +70°C

• Low self‑discharge, enabling multi‑year deployments

This chemistry ensures reliable operation even after long periods of inactivity.

Key Technical Characteristics

The Saft M 52 EX SV delivers dependable performance in compact, safety‑critical devices:

• Compact cylindrical format for space‑constrained designs

• Strong pulse performance for RF transmissions, sensing, and telemetry

• Hermetically sealed construction for leak‑proof durability

• Long shelf life with minimal voltage drop during storage

• High energy density relative to its size

• Designed for long‑term, maintenance‑free operation

These characteristics make the M 52 EX SV suitable for both continuous low‑drain operation and periodic high‑drain events.

Common Applications for the Saft M 52 EX SV

The M 52 EX SV is widely used in industries where intrinsic safety, long‑term reliability, and compact size are essential:

• Oil & gas instrumentation (pipeline sensors, pressure transmitters, flow meters)

• Petrochemical and refinery monitoring systems

• Mining safety equipment

• Hazardous‑area IoT sensors and wireless modules

• Utility metering (AMR/AMI) in explosive zones

• Industrial safety systems and gas detectors

• Asset tracking in hazardous environments

• Environmental and structural monitoring

These applications benefit from the M 52 EX SV’s ability to deliver stable voltage and dependable pulse performance while meeting strict safety certifications.

Why Engineers and OEMs Choose the M 52 EX SV

• Certified for hazardous and explosive atmospheres

• High pulse capability for RF and sensor‑driven workloads

• Stable 3.0V output for sensitive electronics

• Low self‑discharge for long‑term storage and deployment

• Wide temperature tolerance for extreme industrial environments

• Proven reliability in mission‑critical, safety‑regulated systems

• Maintenance‑free operation for sealed or remote devices

The M 52 EX SV is often selected when designers need a compact, EX‑rated, pulse‑capable Li‑MnO₂ power source that can operate safely and reliably for years without maintenance.
