The AL6M-P4-R is an LED illuminated pilot light designed for compact industrial control panels and signaling applications. It features a 16mm round lens with a standard 18mm lens size, SPDT (Single Pole Double Throw) contact configuration, and is available in both IP40 (dustproof) and IP65 (watertight/oiltight) protection ratings. The device operates at a maximum voltage of 250V AC/DC with a thermal current rating of 3A and a minimum applicable load of 5V AC/DC at 1mA, utilizing gold-clad silver contacts for reliable low-level switching. The LED lamp includes a built-in current-limiting resistor and reverse polarity protection diode, eliminating the need for external components. Operating across a temperature range of -25°C to +55°C with snap-action contacts and .110" solder or quick-connect terminal options, this pilot light is ideal for status indication, alarm signaling, and process monitoring in manufacturing, automation, and control systems.
