LED Indication - Discrete is an electronic component which uses an LED, a Light Emitting Diode, to indicate an on and off state. The HLMA-PL00-N0021 is an example of this component, used for low current applications, making them suitable for applications where low current is required, such as in sectors like industrial automation, signals for safe and hazardous zones, switching, signaling, monitoring and in overall lighting control systems.

Acting as both a receiver and a transmitter, the HLMA-PL00-N0021 uses the emission of light from the LED to indicate that a signal or a circuit is powered, allowing operators to visualize the current state of an input or output. The short-circuit or open-circuit connection prevents false operations that may lead to malfunction of the system.

The HLMA-PL00-N0021 is a discrete LED indicator, meaning that it only emits light in one direction and has an LED in its most basic form. This means that it is reliable and efficient due to its simple construction and LED indicator’s remarkably long life span, a typical one expected to last up to 50,000 or 100,000 hours, making it suitable for lengthy operations. Also, in comparison to most industrial automation components, it is lightweight and compact in size, having a size of 5.4 mm x 4.4mm.

The working principle of the HLMA-PL00-N0021 is quite straightforward: electric current is converted into light by a few intricate processes. First, a constant electric current passes through the LED anode, which is connected to the cathode by an electric field. The current causes electrons to overlap and generate photons or particles of light, turning on the LED light as a result. The electric current is then halted by a resistor, located within the package, to stabilise the access of current.

It is important to note that the HLMA-PL00-N0021 is different from ordinary LEDs in terms of its working principle. Ordinary LEDs emit light in two directions and are powered with direct current (DC). The HLMA-PL00-N0021 is designed with reverse polarity protection and does not require a fixed voltage or current. This makes it reversible and safe in the event of a voltage reversal. Furthermore, its working temperature ranges from -40 to +85ºC

The HLMA-PL00-N0021 application field is mainly in industrial automation like signal indication, switch grading and multi-tone sound generation. In addition, the HLMA-PL00-N0021 can be used to control multiple device switch states during a single operation, such as operating fan lights or alarms. Moreover, it is also suitable for use in other areas like medical equipment, automobile and household appliances.

In conclusion, the HLMA-PL00-N0021 is a simple and efficient LED discrete indicator. Its low power consumption makes it suitable for many applications such as industrial automation, signal indication and switch grading. Furthermore, its long life expectancy of up to 50,000-100,000 hours makes it a viable cost-effective option for various applications.
