Pressure switch for Demag AC80-1

The pressure switch with part number 551 420 40 is a component used in the Demag AC80-1 all-terrain crane. This device monitors the pressure of hydraulic oil or air within the machine systems and triggers an electrical circuit when the pressure reaches a specific pre-set value. By managing these pressure thresholds, the switch allows the crane to respond automatically to operational conditions, such as activating alarms, stopping specific functions, or engaging pumps to maintain required system levels.

This component is compatible with the Demag AC80-1 model. It serves as a critical safety and control element, helping to prevent damage from overpressure or identifying potential issues like pressure drops that may indicate leaks or system malfunctions. The device is manufactured to meet the technical requirements of the machine, ensuring that the hydraulic and pneumatic circuits operate within their intended safety parameters.

In heavy machinery, pressure switches function as automated sensors that translate pressure changes into electrical signals. These signals are used by the machine control system to regulate various hydraulic or pneumatic processes, ensuring that the equipment maintains consistent performance and operational safety during lifting and maneuvering tasks.
