ATEN Capacitive Leakage Sensor

EA1540

  • Highly reliable – instantaneous liquid detection and alert
  • Anti-interference – avoids external signals from affecting its normal operations
  • Durable – built with corrosion-resistant material

The ATEN Leakage Sensor EA1540 is an intelligent liquid detection solution designed to help protect critical power infrastructure and connected equipment from water-related damage. Working seamlessly with compatible ATEN PDUs, the EA1540 continuously monitors its surroundings and instantly alerts users when liquid is detected nearby.

When a leak is identified, the sensor immediately activates its built-in audible alarm and red LED indicator, enabling rapid response to potential threats before they can impact power distribution systems or connected devices. This proactive monitoring helps reduce downtime, prevent equipment failures, and improve overall operational reliability.

The EA1540 features a compact, space-saving design that is ideal for installation in environments where equipment protection is essential. Its advanced anti-interference construction minimizes the impact of external signals, ensuring accurate and dependable detection performance. Built with corrosion-resistant materials, the sensor is also suitable for deployment in challenging environments with high humidity or increased exposure to environmental hazards.

Designed for critical infrastructure applications, the EA1540 is particularly effective in underground data centers, utility facilities, server rooms, network closets, and other locations where early leak detection is essential for maintaining uninterrupted operations.
