Capacitive Leakage Sensor ATEN EA1540 DC AC 10-30V 0.15A

The ATEN EA1540 Capacitive Leakage Sensor detects the presence of liquid near a connected PDU and alerts operators when moisture is detected. On detection, the unit emits an audible beep and lights a red LED to indicate the location of the leakage. The compact, corrosion-resistant housing and anti-interference design make the EA1540 suitable for confined or electrically noisy installations such as underground subway data centers. The sensor accepts DC or AC input voltages from 10 to 30 V and provides a nominal current output of 0.15 A.

Advantages

The EA1540 reduces the risk of damage to PDUs and powered equipment by providing immediate local notification of liquid ingress. Its capacitive sensing avoids false triggers from external electrical noise, while corrosion-resistant materials increase durability in harsh environments. Small dimensions (85 mm × 110 mm × 45 mm) allow easy integration into existing racks or cabinets without occupying excessive space.

Suitable for

• Data center PDUs, including underground or subway installations
• Server rooms and equipment racks where liquid detection is required
• Environments with electrical interference where stable sensing is needed

How to use

Mount the EA1540 near the PDU or at locations where liquid ingress is most likely to occur. Connect the sensor to a compatible power source within the 10–30 V range and verify the wiring to the monitoring or alert system if required. When the sensor detects liquid, it will sound the internal beeper and illuminate the red LED; inspect the indicated area and address the leak immediately. Routine visual checks ensure the sensor remains free of debris and properly positioned.

Recommendations

The sensor should be installed in close proximity to PDUs and in low points where liquids collect. Avoid placing the unit where constant splashing or deliberate immersion may occur. For reliable long-term operation, perform periodic inspections, keep the sensing area clean, and use corrosion-resistant mounting hardware in harsh environments.
