Product Advantages and Features
1.High security and compliance
International certification:
Compliant with IEC 60947-5-5, EN 418 (Mechanical Safety Standard), UL, CE and other certifications, ensuring reliable emergency stop function.
Meet global market access needs through regional standards such as CCC (China Compulsory Certification).
Visual warning design:The red mushroom head button with a yellow background circle (compliant with ISO 13850 standard) allows for quick recognition even in high noise or chaotic environments.
Forced disconnection structure (NC contact):Normally closed contact design, physically cutting off the circuit during emergency stop to avoid safety risks caused by electronic component failures.
2.Excellent mechanical durability
Ultra long lifespan: The mechanical lifespan can reach over 500000 cycles (some models), suitable for harsh industrial environments with high-frequency operations. The contacts are made of silver alloy material, which is arc resistant, wear-resistant, and has a long electrical life.
Shock and vibration resistance: The sturdy engineering plastic or metal casing design is resistant to mechanical shock and vibration (in accordance with IEC 60068-2 standard).
3. Flexible design and installation
Multiple button sizes and types:
Mushroom head diameter: Φ 40mm (standard), Φ 60mm (large, such as A22E-L)
Model with LED indicator light (A22E-R): Real time display of device status.
There are various installation methods: panel installation (with a hole diameter of 22.5mm), surface installation (A22E-S), and rope pulling (A22E-LT).
4.Reliable electrical performance
Multiple contact configurations: Provide combinations such as 1NC (single normally closed), 1NC+1NO (normally closed+normally open), etc., to flexibly match control circuits.
High load capacity: The rated load can reach AC250V/6A or DC24V/4A, directly driving contactors or safety relays.
5.Maintain convenience
Modular design: The button head can be quickly replaced (such as the A22E-M series) without the need to disassemble the entire switch.
Status visualization window (some models): Built in LED indicator light, displaying emergency stop trigger status for easy troubleshooting.
