Product Description
The Omron K7L-AT50B Liquid Leak Sensor is engineered for high-sensitivity leak detection in industrial, HVAC, manufacturing, and water treatment environments. It utilizes a wide sensitivity range (250KΩ to 50MΩ) to reliably spot even minor liquid leaks, minimizing potential damage and downtime. This sensor is ideal for the early detection of fluid presence in control systems, machinery, enclosures, and process lines.
Equipped for DIN rail mounting, the K7L-AT50B ensures straightforward installation within electrical and automation panels. The sensor operates with a flexible power supply range (12 to 24V DC) and delivers both PNP and NPN output signals, facilitating integration with diverse monitoring or alarm systems. It features a rapid response time of 800 ms and supports reliable detection with a single input and output configuration.
The sensor's robust construction includes compact dimensions (12.8 mm length, 28.8 mm depth, 46 mm width) and a secure screw terminal interface. Its operational temperature (-10°C to 55°C) allows continued functionality in challenging industrial settings. This design, along with compliance to CE, CSA, cULus, and UL standards, positions the K7L-AT50B for universal acceptance in regulated installations.
Applications span the monitoring of pumps, valves, tanks, and pipework for leak-related faults, preventive maintenance in manufacturing lines, water ingress detection in HVAC systems, and safety assurance in water treatment facilities. The wide sensitivity range efficiently identifies small leaks, ensuring early warning and reducing the risk of operational disruptions.
Industries benefitting from this sensor include Industrial Automation, HVAC, Water Treatment, Manufacturing, Facility Maintenance, Commercial Plant Operations, and Laboratory Safety.
