The WL10-NP-2 is an optical spot-type liquid leakage sensor featuring advanced optical technology that eliminates the need for a shade-plate or external amplifier. The sensor contains an internal LED and a photodiode (PD); light is reflected by a prism under normal conditions and transmitted/diffused when liquid makes contact, triggering a detection. It features a compact, thin design (φ25 mm, t=10 mm) and is housed in Polypropylene (PP), making it suitable for water leak detection. The device operates on a 12-24V DC supply and provides an NPN open collector output. It includes a built-in LED indicator that remains green during normal operation and turns red when a leak is detected. The sensor is rated IP67 for waterproof and dustproof performance.
