Video Description:
In this video, we take a close-up look at the ONN-M4EX explosion-proof signal tower light and demonstrate how it performs in hazardous industrial environments. You'll see its aluminum-alloy housing and tempered-glass cover, watch the steady-on, flashing, and buzzer modes in action, and learn how the dual contact/PNP-NPN signal inputs wire into common PLC systems. We also show the optional voice-broadcast feature with custom MP3 uploads via Micro-USB, plus real installation and mounting details for wastewater, port, metallurgy, gas, and mining applications.
