Complete emergency stop button, 2NC unlock by rotation F40 XB4BS8444

Emergency stop button for industrial and other applications

This complete emergency stop button, identified by catalog number XB4BS8444, is a reliable solution for ensuring safety in a variety of applications. Designed for mounting in 22.5 mm diameter holes, it is a key element of machine and workstation safety systems. Its robust construction and high IP66 protection rating guarantee resistance to harsh environmental conditions such as dust, water and vibration.

Construction and operation

The button features a twist-release mechanism, providing intuitive and quick restoration of machine operation after the hazard has been removed. The mushroom head, 40 mm in diameter, is made of metal, increasing its strength and resistance to mechanical damage. A 2NC (two normally closed) contact configuration provides redundancy – in the event of a failure of one contact, the other will still effectively break the circuit, increasing the level of safety. Connection of the auxiliary circuit is made using a screw connection, guaranteeing a stable and durable connection of the wires.

Applications and benefits

The XB4BS8444 safety button finds wide application in:

• Production machines and assembly lines: Quick stopping of processes in emergency situations.
• Control panels: Immediate ability to stop operations by the operator.
• Robotics and industrial automation: Emergency shutdown of robots and automated devices.
• Workshops and industrial halls: Protection of machine tools, presses and other potentially hazardous equipment.

Thanks to its construction and IP66 certificate, the button works perfectly in demanding industrial conditions, providing reliable protection against dust and strong jets of water. The twist-release mechanism is easy to use, and the standard 22mm mounting hole facilitates integration with existing control panels. This is an ideal solution for installers looking for a reliable component for building safe control systems and for end users who value a high level of work safety.
