This Harmony XB7, emergency stop / shutdown 40mm mushroom head monolithic red push button operates with a latched turn to release mechanism and uses screw-clamp terminals. This emergency stop / shutdown button, also called EMS (Emergency Machine Stop) and EMO (Emergency Off) is easily installed into a standard 22mm diameter cut-outs and connected with simple screw-clamp connections. It is clearly distinguishable visually at a distance thanks to a clear color and a prominent 40mm mushroom shape. It is impact resistant, dust resistant, water resistant and vibration resistant thanks to its IP65, making it ideal for operation in harsh environments. It has a double insulated plastic bezel. Its wide range of operating temperatures from -40°C to 70°C allows versatility in usage of product.
