How do ATEX-certified EX-AZM300 interlocks mitigate explosion risks in mining operations while optimising procurement costs?

The EX-AZM300 is an ATEX-certified safety interlock designed for use in explosive environments, such as those encountered in mining operations. The interlock is certified for ATEX Zones 2 (gas) and 22 (dust), and it is designed to withstand ignition sources —a vital safety requirement in volatile settings.

The EX-AZM300's robust, sealed structure and IP66/IP69 protection ratings provide excellent resistance to water, dust, and corrosive elements. This ensures consistent operating in both underground and surface mining environments. The failure-safe and tamper-resistant design is critical. Its fail-safe mechanism ensures that the interlock deactivates safely during power outages, preventing harmful access. It reduces the possibility of manipulation or circumvention when combined with a high coding level that complies with ISO 14119.

The integration of RFID technology improves this protection. Coded RFID actuators enable only the selected guard or door to be opened, preventing tampering and ensuring controlled access. Global certification enables the same unit to be used continuously across multinational sites, thereby increasing operational efficiency and procurement savings. Multi-functionality is also advantageous if a single device provides guard locking, safety interlocking, and explosion prevention.

Integrated electronics and diagnostics reduce installation costs by simplifying wiring and streamlining the process, saving time. LED diagnostics ease troubleshooting, reducing downtime and staff expenses. A minimum lifespan of one million operations is ensured by the durable housing's ability to endure mining conditions. This reduces replacements and lowers long-term maintenance expenses.
