Product information

Description

The Siemens SIRIUS ACT Emergency Stop Mushroom Pushbutton is a high-performance industrial control device engineered for safety-critical applications. Featuring a 40mm red actuator head, this unit is designed to provide immediate machine shutdown in hazardous situations. It adheres to the EN ISO 13850 standard, ensuring reliable performance and positive latching when activated. The device is built with a durable, shiny metal housing and includes a yellow backing plate with the inscription NOT-HALT, making it highly visible and compliant with safety regulations.

Advantages

This emergency stop button benefits from an innovative snap-on installation concept that allows for one-handed mounting without the need for specialized tools. The integrated twist prevention feature ensures the unit remains securely in place during operation. Its robust construction provides a high degree of protection against environmental factors, including dust, oils, and caustic solutions, and it is even resistant to high-pressure water jet cleaning. The inclusion of a holder and contact modules makes it a complete, ready-to-install solution for industrial safety systems.

Suitable for

  • Industrial machinery and production lines
  • Safety-critical control panels
  • Outdoor industrial environments
  • Systems requiring EN ISO 13850 compliance

This device may not be suitable for applications requiring a specific release mechanism other than the rotate-to-unlatch function, such as key-operated or pull-to-unlatch requirements. Additionally, it is intended for standard industrial control circuits and should not be used in environments that exceed its specified protection ratings or electrical load capacities.

Key specifications

  • Actuator diameter: 40 mm
  • Mounting diameter: 22 mm
  • Color: Red
  • Release method: Rotate-to-unlatch
  • Contacts: 1 NC + 1 NC
  • Terminal type: Spring-type
  • Material: Shiny metal
  • Standards: EN ISO 13850

Installation is straightforward due to the snap-on design. The unit is mounted into a 22mm hole, and the integrated twist prevention eliminates the need for additional grooving. Once the holder is secured, the contact modules can be attached easily. The device is designed for intuitive operation; in an emergency, the user presses the mushroom head to latch the circuit, and it is reset by rotating the head according to the manufacturer's instructions.

What to consider before purchase

  • Verify that the 40mm mushroom head size meets your specific safety layout requirements.
  • Ensure the rotate-to-unlatch mechanism is appropriate for your operational safety protocols.
  • Check that the spring-type terminal configuration is compatible with your existing wiring infrastructure.
Ensure that the emergency stop button is positioned in an easily accessible location for operators and that the yellow backing plate is clearly visible to comply with safety standards. Regular testing of the latching and release mechanism is recommended to maintain system integrity.
