From Rugged Computers to Explosion-Proof Terminals: How Emdoor Enhances Safety in Industrial Environments

Amid global digital and intelligent transformation in industry, Emdoor—a leading A-listed enterprise in the rugged terminal sector—has established itself as a key provider of rugged computers and vehicle-mounted industrial devices. With strong technical expertise and extensive industry experience, Emdoor’s products serve as critical tools linking production and management, and are widely used in manufacturing, warehousing, transportation, utilities, and more.

However, in flammable and explosive environments such as those found in oil, gas, chemical, and coal mining operations, conventional rugged devices can pose significant safety risks. During operations, when the concentration of explosive gases or dust in the air exceeds a critical threshold, traditional equipment may generate electrostatic sparks, potentially triggering combustion or explosion.

Emdoor Explosion-Proof Terminals—Specialized Equipment for High-Risk Industries

To address the needs of flammable and explosive environments across various industries, Emdoor has launched three explosion-proof products:

1. EM-I17J(EX) Rugged Tablet
2. T1 Outdoor Rugged Tablet
3. P1 / H68T Outdoor Rugged Phone / Handheld Terminal

These devices are specifically engineered for high-risk sectors such as petrochemicals and coal mining. Each product complies with stringent explosion-proof design and certification standards, ensuring operational safety by preventing sparks or thermal effects—even in the presence of explosive gases or dust.

Intrinsic Safety (EX)—Setting the Benchmark in Industrial Explosion Protection

All three Emdoor explosion-proof products are ATEX-certified, with ratings of Ex ic IIC T4 Gc and Ex ic IIIB T130°C Dc. They provide reliable safety in Zone 2 environments with Group IIC gases (e.g., hydrogen, acetylene, carbon disulfide) and Zone 22 environments with Group IIIB non-conductive dust (e.g., flour, wood chips).

Compared to devices with IIB and IIIA ratings, Emdoor’s terminals support a broader range of explosive gas and dust environments, delivering higher levels of safety in volatile conditions.

Triple Explosion-Proof Protection—The Core Shield for Safety

Emdoor’s explosion-proof products utilize an intrinsically safe circuit design, implementing triple protection across three core dimensions—mainboard, battery, and housing—to eliminate ignition risks at the source.

01 Mainboard Protection
- Circuit Protection: High-reliability components with overcurrent, overvoltage, and short-circuit protection.
- Current Limiting: Strict control of current, voltage, and power to prevent energy levels that could ignite gases.

02 Battery Protection
- Charge/Discharge Control: Monitors and manages battery activity to prevent overcharging or over-discharging.
- Thermal Management: Automatically disconnects the circuit in case of high temperature or pressure.
- Separator Protection: High-density coated separators provide insulation and thermal resistance.

03 Housing Protection
- Rugged Design: MIL-STD-810H/G and IP65/IP68 ratings for dust, water, and drop resistance.
- ESD Protection: Withstands ±8kV contact discharge and ±15kV/±12kV air discharge.
- Impact Resistance: Vibration- and shock-proof design to safeguard internal components.

Beyond Explosion Proofing

Emdoor’s explosion-proof terminals offer more than just safety. They are equipped with rich functionalities tailored to real-world applications, making them ideal for mining, emergency response, and other critical fields.

Important Usage Guidelines

1. Batteries should only be replaced or charged in areas confirmed to be non-hazardous.

2.  In hazardous locations, the battery lock must remain engaged.

3.  Only use genuine Emdoor batteries.

4. Expansion ports, docks, and side I/O interfaces are not suitable for use in hazardous environments.

5. Operating temperature range: -20°C to 60°C.
