The 5110F1-12V is a red LED panel mount indicator from the 5110F series, featuring a T-1 (3mm) LED with a diffused lens for wide-angle viewing. It operates directly from a 12V DC supply due to a built-in chip resistor, drawing a typical forward current of 13 mA and producing a luminous intensity of 8.0 mcd at a peak wavelength of 655 nm. This indicator is designed for easy press-fit installation, snapping into a 0.157-inch panel hole. It is suitable for various applications including panel indication, electrical panels, industrial equipment, and appliances.
