The PL22CTLB110 is a panel-mounted two-colour pilot light indicator designed for industrial control panels and equipment status indication. It features a 22mm diameter housing with high-brightness LED technology, delivering ultrahigh brightness of =100cd/m² with pure colour output in red and green configurations. The unit is rated for 110VAC/DC operation with an allowable voltage fluctuation of ±20%, operates across a frequency range of 50-60Hz, and maintains a continuous operating life of =100,000 hours. With an IP 65 degree of protection rating and compliance with IEC/EN 60947-5-1, IEC/EN 60073, IEC/EN 60529, and UL 508 standards, this indicator provides reliable visual feedback across industrial environments with operating temperatures from -25°C to +70°C. The low current consumption of =18mA and robust construction make it ideal for long-term panel-mounted applications requiring durable, high-visibility status indication.
