Emergency STOP head (push-pull), red Ø40, non-illuminated EN 418 023874

Emergency STOP head for professional control systems

The red mushroom head Ø40 mm from the OSMOZ series by LEGRAND is a specialized component designed for emergency shutdown in industrial applications and automation. The product complies with the EN 418 standard, making it an ideal solution for machine and equipment safety systems.

Construction and operating mechanism

The head is made of plastic with high mechanical resistance, featuring a round lens with a diameter of 40 mm. The characteristic "push-pull" mechanism allows for unblocking by pulling, ensuring intuitive operation in emergency situations.

The "non-self-resetting" design guarantees that it remains in the stop position after activation - the element does not automatically return to the working position, which is crucial for the safety of industrial processes. Mounting is standard via a 22,5 mm hole, and the high button profile facilitates quick identification and operation even when wearing protective gloves.

Environmental protection and compatibility

The device provides an IP66 protection class, guaranteeing full resistance to dust and water jets - it performs well both indoors and outdoors. Additionally, it meets the NEMA 4X standard, providing protection against corrosion and harsh weather conditions.

The yellow front ring made of plastic serves a signaling function - the characteristic color immediately informs about the safety function of the component. The lack of illumination capability is compensated by the intense red color of the mushroom head itself, which remains clearly visible under various lighting conditions.

Application in automation systems

The component is ideal for use as an emergency STOP button in control panels, control enclosures, and operator consoles. It is used in the control of electric motors, pneumatic drives, and any devices requiring an immediate stop of operation.

Thanks to standard mounting dimensions, it is compatible with most modular accessory systems available on the market. The product is a key element in building comprehensive machine safety systems that meet current legal requirements regarding the protection of workers in the processing and manufacturing industries.
