Winland W-S-U Water Sensor, Surface, Unsupervised, Accessory Sensor for WaterBug WB200 and WB350

Protect critical infrastructure from costly water intrusion with the Winland Electronics WaterBug W-S-U wired water sensor. Designed as an accessory sensor for the WB200 and WB350 systems, this surface-mount liquid leak sensor provides reliable, fail-safe detection where it matters most—server rooms, document storage, warehouses, basements and sump pump areas. The sensor trips when water bridges its contacts, delivering immediate notification to your monitoring or security platform so you can act before damage spreads.

Installation is straightforward: a 15' prewired cable and compact 3.0" x 2.0" x 0.88" form factor let you mount the sensor on floors or flat surfaces with minimal disruption. You can network up to six W-S-U sensors to a single WB200/WB350 device and place them up to 100' away using standard 18–22 AWG twisted-pair wiring for broad area protection. As a hardwired component, the W-S-U is ideal for integration into building security, surveillance and facility monitoring systems that require dependable, continuous performance.
