Selection Notes

The 230...240 V AC supply lets this buzzer wire directly to a mains-fed signal circuit without a step-down transformer, which the 24 V XB5KS2B4 variant would need in that same panel. The red lens suits alarm or fault indication; the 230 V yellow XB5KS2M8 covers caution signalling instead. Current draw stays under 35 mA, so it adds negligible load to an existing 230 V control circuit. The IP66/IP67/IP69 rating and UL type 4X/13 enclosure make it a fit for panels exposed to hose-down cleaning or humid outdoor cabinets.
