The Q8F1BYYRG02E is an 8 mm panel mount LED indicator featuring a bi-color Red/Green LED within a flush, black-finished bezel. This model is configured with solder lug/faston terminals and does not include an internal resistor, requiring an external one for operation. It is IP67 sealed for protection against dust and water ingress, ensuring reliability in demanding environments. The color is changed between red and green by reversing the polarity of the supply voltage. With an operating temperature range of -40 °C to +85 °C, this indicator is well-suited for industrial control panels, status signaling, and other applications requiring dual-state visual feedback.
