The LPMLB4 is an integrated monoblock pilot light designed for steady light indication in industrial control and signalling applications. It features a red LED element with a rated auxiliary supply voltage of 24 VAC/DC, providing reliable visual feedback in control stations and panel-mounted systems. The unit is constructed with polyamide materials and is designed for any mounting position, offering robust performance in severe ambient conditions with double breaking action and self-cleaning contact operation. It operates reliably across a temperature range of -25°C to +70°C and meets stringent protection standards including IP66, IP67, and IP69K per IEC/EN standards, as well as UL Type 1, 2, 3R, 4, 4X, 12, and 12K ratings. The LPMLB4 is ideal for use in industrial machinery, process control systems, and emergency signalling applications where durable, weather-resistant indication is required.
