K2752-5 - DownFlex 400-MS/A Auto-Start Motion Sensor Kit

Automated Control for DownFlex Systems

The Lincoln Electric K2752-5 Motion Activated Start/Stop Sensor is a precision-engineered accessory designed to enhance the operational efficiency of the Lincoln Electric DownFlex 400-MS/A downdraft table. This device integrates directly with the table's control system to provide fully automated management of the fume extraction fan. By utilizing advanced motion sensing technology, the unit detects activity within the workspace above the grid, triggering the extraction system immediately when the operator begins handling materials or welding.

Installation is designed for seamless compatibility with the 400-MS/A infrastructure. The sensor module mounts firmly to the top of the back panel or backdraft panel, ensuring an unobstructed field of view over the welding zone. It connects to the system via a dedicated cable that routes to the rear of the downdraft table, interfacing directly with the motor control logic. This setup eliminates the need for complex wiring or third-party adapters, maintaining the integrity of the original equipment manufacturer (OEM) specifications.

A critical feature of the K2752-5 is its intelligent run-out cycle. Unlike simple switches that cut power instantly, this sensor initiates a run-out period when movement ceases. This delay ensures that any residual smoke or particulate matter generated in the final moments of the welding process is effectively evacuated before the fan powers down. This functionality is vital for maintaining high air quality standards while simultaneously optimizing energy usage by preventing the fan from running during extended periods of inactivity.

This sensor is an essential component for facilities aiming to modernize their fume extraction protocols. It ensures that the safety equipment is active exactly when needed, removing the reliance on operator memory to turn the system on. The result is a safer environment, reduced wear on the extraction motor, and lower overall utility costs for the workshop.
