Import Black Shell Led Flash Buzzer Round Head Buzzer — Buy in wholesale FOB from Supplier in China

The AD16-22CS series indicator light with integrated LED flash buzzer is a 22 mm panel-mount signal device manufactured by Zhejiang Ninuo Electric Co., Ltd in Yueqing, Zhejiang Province. The round-head buzzer variant combines a visual LED pilot lamp with an audible annunciator in a single 22 mm cutout, reducing panel space compared to separate lamp and horn installations. Lamp voltage options span DC/AC 6 V up to 380 V, covering control-circuit, mains, and industrial distribution voltages commonly found in switchgear and automation panels.

Housing material is a black ABS or polycarbonate plastic shell rated to IP65 for dust and low-pressure water-jet ingress protection, suitable for indoor panel and protected outdoor enclosure mounting. The LED element is rated for greater than 30,000 hours of continuous operation at 50-60 Hz, with flash or steady-burn modes depending on the specific sub-model ordered. Colour options include white, green, red, yellow, and blue, allowing conformance to IEC 60073 or local colour-coding standards for machine status indication. Terminal configuration is typically screw-clamp or plug-in, standard for 22 mm industrial indicators.

Primary applications span CNC machine tool status panels, conveyor system alarm stations, electrical distribution switchgear, and process-control cabinetry. Buyers are typically OEM panel builders, system integrators, and maintenance-repair operations in factory automation, building management, and infrastructure sectors.
