Emergency STOP switch – Ex ATEX mushroom head
The Ex ATEX emergency mushroom safety switch is a device belonging to the control apparatus, used in potentially explosive atmospheres. It is used for immediate stopping of machines, equipment and entire process lines in emergency situations or in cases of danger to the health and life of employees. The mushroom safety switch can be unlocked by twisting or pulling. It can also be fitted with an additional protective collar to minimise the risk of accidental activation.
The HARDO brand emergency mushroom switch is ATEX-compliant, meaning that it meets strict safety standards for equipment used in potentially explosive atmospheres. It is mainly used in the chemical, oil and gas industries. This emergency stop allows for quick disconnection of energy sources in an emergency situation, minimising the risk of explosion or fire.
Immediate emergency response
The mushroom switch allows immediate response in an emergency situation, minimising potential risks to human health and life and protecting property and infrastructure from damage. It is equipped with features that allow easy and quick activation even in difficult conditions.
Use of emergency stop switches
The design of ATEX emergency switches meets the stringent requirements of the operating environment, which guarantees their reliability and long-lasting performance. Their installation is mandatory in many industrial sectors. These circuit breakers are a key component of safety systems in the chemical, petrochemical and energy industries, and wherever production processes or the storage of substances can lead to an explosive atmosphere.
Robust housing construction – protection against mechanical damage
The design of the emergency stop is based on a housing made of glass fibre reinforced polyester, which increases resistance to mechanical damage and provides excellent protection for the internal components. The robust housing further protects the device from external influences, guaranteeing safe use and reliable operation in Ex zones.
Application-specific customisation
As a manufacturer of electrotechnology and lighting for hazardous areas, HARDO makes it possible to flexibly adapt products to specific user requirements. With a choice of suitable technical parameters and additional accessories, Ex switches can be configured according to the needs of the industrial application. The available options cover different voltage ranges, allowing the devices to be integrated into a wide range of industrial systems.
