Mini/maxi contactor for Terex ATT400-3

The mini/maxi contactor, part number H-65416-67, functions as a limit switch or level sensor within the electrical and electronic control systems of the crane. It detects when a specific parameter, such as fluid level, component position, or pressure, reaches a pre-established minimum or maximum threshold. Upon reaching these limits, the device sends a signal to the machine control system to activate or deactivate specific operations, ensuring the equipment functions within safe parameters.

This component is designed for the Terex ATT400-3 all-terrain crane. It is commonly utilized to monitor hydraulic oil levels, boom extension limits, or the positioning of the outriggers during setup and operation. Proper calibration and function of this sensor are necessary for the control system to maintain operational safety and prevent equipment damage or system errors during use.

In heavy machinery, these contactors act as feedback devices that allow the control unit to manage automated processes. Depending on the specific application, they may operate as mechanical limit switches, pressure sensors, or fluid level floats. By providing accurate status data to the crane controller, they assist in the management of safety interlocks and operational sequencing.
