This control station with mushroom head push-button for emergency stop function is ideal for situations where quick actions are required for a process or machine to function correctly or where operator movements require maximum ergonomy. Its schematic is clearly distinguishable thanks to clear colors. It is impact resistant, dust resistant, water resistant, corrosion resistant, and vibration resistant thanks to its IP65, making it ideal for operation in harsh environments.
