The 621-1142-304F is a 22mm heavy-duty tri-color LED panel mount indicator designed for industrial signaling applications with red and green color options. It operates at 6V DC with an internal resistor included, drawing 15 mA of current and providing typical light intensities of 115 mcd for red and 110 mcd for green. The indicator features a stainless steel housing, terminals, and nut for superior corrosion resistance, making it suitable for both indoor and outdoor environments, and is secured with IP66/IP67 protection and IK10 impact rating to prevent dirt, dust, and water penetration. With a mounting hole size of 0.866" (22 mm), maximum panel thickness of 0.394" (10 mm), and operating temperature range of -25°C to +70°C, this indicator is ideal for main power indication, remote power indication, status indication, maintenance and warning indication, and instrumentation applications.
