LED indicator is a product of the technology-based industry focused on illuminated indicators. Discrete indicators, also known as single point indicators, are designed to indicate a single state or process. The VAOL-S12SB4 is a single point indicator designed to offer a reliable and affordable way of monitoring circuit states and providing visual feedback on activities. This article will discuss the application field and working principle of the VAOL-S12SB4.

Application Field

The VAOL-S12SB4 is designed to be a reliable and affordable solution for any single point indication need. It can be used in a variety of applications in both industrial and consumer devices. These include automotive, aerospace, medical device, home appliance, industrial machine, military defense, and other industries. It can be used to indicate movement from one state to another in any application such as flow/presence detection, voltage, temperature or pressure monitoring, and logic level state detection.

The VAOL-S12SB4 is a highly versatile product with a long list of applications. Its robust design and simple operation makes it suitable for a wide range of industrial and consumer applications. In addition to traditional indicate purposes, this product can be used for 2-color lighting in antiglare type, reverse current detection, and dimming control. The VAOL-S12SB4 is also suitable for harsh environment applications where resistance to electric shocks and vibration is required.

Working Principle

The VAOL-S12SB4 is a single point indicator with a red LED. It operates with a DC operating voltage range between 3.2V to 36V and can use currents up to 40mA. The device is designed to provide reliable visual indications and is available in both personal and surface mount versions. The personal mount version has a compact size and contains a built-in resistor which limits the current to the right level. The surface mount version has a larger size and must use a resistor for current control.

The indicator produces an illuminated red LED when the terminal is connected to the positive DC operating voltage. The LED can be turned off by detaching the terminal from the positive DC operating voltage or by applying a voltage of reverse polarity. When the terminal is reconnected to the positive DC operating voltage, the LED will remain illuminated. This basic on/off principle allows the VAOL-S12SB4 to be used in a variety of applications including break protection, power-up sequencing, presence/absence detection, logic level state detection, and others.

The VAOL-S12SB4 offers a simple way to illustrate a single state or process. The long list of applications, robust and versatile design, and simple operation make it an ideal choice for a wide range of applications. This product is designed to offer a reliable, cost-effective, and safe solution for a variety of industrial and consumer needs.
