BIRA HARTTE MG280SR 280kg Cerradura electromagnética de puerta con supervisión de estado de puerta y señalización LED

Unlike conventional electromagnetic locks that require separate sensors and indicators, the BIRA HARTTE MG280SR integrates door status monitoring and LED signaling into one robust unit. This 280 kg (600 lbs) holding force lock is built for high-traffic access control points where reliability and real-time feedback are essential. Its built-in NO/NC/COM relay outputs and clear visual status indication streamline installation and enhance security oversight.

Highlights

• 280 kg (600 lbs) holding force for secure door locking
• Integrated door status sensor with NO/NC/COM outputs for monitoring
• LED status indicator: green when locked, red when unlocked
• Selectable 12V DC / 24V DC input voltage for flexible integration
• Fail-safe operation (power to lock) ensures safety in emergencies
• Durable anodized aluminum housing with high-strength steel armature plate
• Built-in MOV surge protection and anti-residual magnetism design
• Tested to 500,000 cycles for long-term reliability

In daily use

Installed on wooden, glass (with U-bracket), metal, or fireproof doors, the MG280SR provides dependable locking for offices, server rooms, and controlled entry zones. The 5-wire connection (Power+, Power-, NO, NC, COM) allows straightforward integration with access control systems, intercoms, or alarm panels. The LED indicator gives immediate visual confirmation of lock state, while the monitoring relay enables remote supervision. With selectable 12V or 24V DC operation and a current draw of 500mA at 12V or 250mA at 24V, it adapts to various power setups. The lock operates in temperatures from -10°C to +55°C and humidity up to 95% non-condensing, ensuring consistent performance in diverse environments.
