Harmony XB4 & XB5 Emergency Stop Push Buttons

Schneider Electric Harmony XB4 and XB5 Emergency Stop Push Buttons offer 40mm mushroom heads and operate with a latched push-pull, turn release, or key release mechanism. These push buttons feature a robust metal or plastic bezel, depending on the model. Emergency Machine Stop (EMS) and Emergency Off (EO) push buttons are easily installed into a standard 22mm diameter cutout and connected with simple screw-clamp connections. These push buttons are clearly visible at a distance due to the clear color and prominent 30mm, 40mm, or 60mm mushroom shapes. Due to the IP66 rating, these push buttons are impact-, dust-, water-, and vibration-resistant, making them ideal for operation in even the most demanding environments. Schneider Electric Harmony XB4 and XB5 Emergency Stop Push Buttons are compatible for installation with XALK and XAPK yellow lid control stations.
