Description The TSF400-0 is a compact water-leak detector designed for early detection of water presence on floors, trays, or inside equipment enclosures. It operates from a wide 4.5–26 VDC supply and provides a N-channel open-drain output for direct connection to PLCs, controllers, alarm modules, or building-automation systems. Detection is based on the conductivity between sensing electrodes; when water bridges the electrodes, the output changes state, enabling fast and reliable alarming. The detector is fully electronic, with no moving parts, ensuring high reliability and long service life. Features Early leak detection; Wide power supply range; N-channel open-drain output; LED status indicator; Rugged IP65 enclosure; Maintenance-free design; Compact and easy to install; Versatile applications.
