The Schneider Harmony XB5 Series presents the ZB5AS944, a robust head for emergency stop push-buttons designed to ensure quick and reliable cessation of machine operations in industrial environments. This component features a prominent red mushroom button with a diameter of 40mm, crafted for easy identification and swift activation in urgent situations.
Constructed with a dark grey plastic bezel and engineered to fit a standard 22mm mounting diameter, the ZB5AS944 is a versatile unit compatible with a range of emergency stop push-buttons. Its trigger action and mechanical latching operation provide tactile feedback, ensuring that the emergency command is unmistakably engaged when pressed.
For added security, the ZB5AS944 includes a key release mechanism, which requires a Ronis 455 key to reset, thus preventing accidental or unauthorised reactivation of machinery. This safety feature is central to maintaining control over the restart process after an emergency stop has been initiated.
The unit is designed to withstand the rigours of industrial use, boasting an IP66/IP67/IP69/IP69K degree of protection, which ensures resistance against dust, water, and high-pressure washdowns, making it suitable for a wide range of challenging environments. Additionally, it meets the NEMA 13 and NEMA 4X standards for protection against environmental factors.
With a mechanical durability rated for 300,000 cycles, the ZB5AS944 is built to last, ensuring consistent performance and reliability. Its compliance with international standards, including EN/IEC 60204-1, EN/IEC 60947 series, EN/ISO 13850, and others, underscores its quality and suitability for global industrial applications.
The ZB5AS944 is an essential component for any safety-conscious industrial setting, providing a reliable and secure method to halt operations swiftly in the event of an emergency.
