This emergency stop/shutdown button, also called EMS (Emergency Machine Stop) and EMO (Emergency Off), is easily installed into a standard 22 mm Dia 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 40 mm mushroom shape. It is impact-resistant, dust-resistant, water-resistant and vibration-resistant thanks to its IP66/IP67/IP69/IP69K, making it ideal for operation in harsh environments.
