The 622-1102-304F is a 22 mm heavy-duty panel mount LED indicator designed for industrial signaling and status indication in demanding environments. This red indicator operates at 6 V DC with internal resistor included, delivering a typical intensity of 200 mcd, and features a mounting hole size of 0.866" (22 mm) with maximum panel thickness of 0.394" (10 mm). The indicator is constructed from stainless steel housing and nut, providing corrosion resistance for both indoor and outdoor use, and is rated IP66/IP67 for protection against dirt, dust, and water penetration. It operates reliably across a temperature range of -25°C to +70°C and is secured with screw terminals and 1 lbs-ft (9.5 N·m) mounting torque. Ideal applications include main power indication, remote power indication, status indication, maintenance and warning indication, and instrumentation systems where robust, non-magnetic, and weather-resistant signaling is required.
