1051QA4

Panel Indicators1051QA4 is an LED panel indicator, which is used to give visual alerts or indicate presence of an electrical condition. It features a bright white light, low current consumption and long service life. It mounts directly to panels, or into suitable accessory bases, and uses a single locking nut for easy installation and removal.The indicator is designed to perform in harsh environments, and is UL approved. It has an operating voltage range of 4 to 30 Volts DC, and can operate in temperatures ranging from -30°C to 70°C. Its maximum current draw is 20mA at 30V DC.Pilot Lights1051QA4 is a pilot light, which is a type of panel indicator. Pilot lights are used to draw the attention of the user to the status of a particular system, such as "on", "off", or "danger".The 1051QA4 is a single pole, illuminated switch which mounts to panel or another flat surface. It requires a minimum installation voltage of 6 volts, and has a maximum operating current of 20mA at 30V DC. The LED illumination is provided by a red or green LED indicator, and the lens offers a shield against bright ambient light.The 1051QA4 can also be operated in temperatures ranging from -30°C to 70°C, and is UL approved for use in the USA, Canada, and most European countries.Working PrincipleThe 1051QA4 LED panel indicator works by using LED technology to produce a bright, white light when connected to the necessary voltage input. The light is activated by the electrical current which passes through the leads connected to the LED.The LED is powered by the DC current provided by the voltage input, and the LED illumination is transmitted through the lens of the 1051QA4. This lens is also designed to provide a shield against bright ambient light, to ensure that the light is still visible in harsh environments.The 1051QA4 LED panel indicator is designed to help identify the state or presence of an electrical condition or system, making it ideal for a wide range of applications, including machine control, security systems, telecommunications, and industrial controls.
