LED indication is widely used for indication purposes, such as object identification, indicating the completion of a process, or indicating different states. Discrete LED indication is particularly applicable when the LED needs to be controlled separately from the surrounding environment and the other indicators. The PCH125-200-BA LED from ASA is one such example.

The PCH125-200-BA LED belongs to the ASACOM family of LED indicators. It is a 5mm (1/5") single-color LED that provides a 120-degree viewing angle. With a lifetime of up to 70000 hours in its standard configuration, it is designed to provide reliable indication in challenging indoor and outdoor applications. The LED comes with a compact, compact flange-type design and is designed to be easy to install and maintain.

The PCH125-200-BA uses the well-known "Principle of the Tunnel", which is based on the tunnel effect. Light is generated by the tunnel effect when electrons pass through a luminescent material such as that used in LEDs. It is caused by an electric current passing through a metal electrode and impinging on a smaller solid-state conductor, such as a metal wire. The current accelerates electrons through the metal wire\'s tunneling barrier, and the resulting electrons are trapped and unable to leave the metal wire. This trapped energy is then released in the form of photon and emitted light.

The tunnel effect is highly dependent on the electrical and material properties of the LED. The PCH125-200-BA LED is designed and manufactured according to demanding requirements and has a stability that has been proven over many years of operation. It is designed to have a low forward voltage and can operate with very low currents, while still providing a consistent and reliable indication.

The PCH125-200-BA is generally applied to power plant control systems, mechanical equipment and asset tracking. In power plants, the PCH125-200-BA can be used to indicate the status of control systems and provide backup warnings. In mechanical equipment, it can be used to identify the various components and provide a helpful visual prompt. In asset tracking applications, the PCH125-200-BA can be used to indicate the current status of a particular item from a distant location.

Overall, the PCH125-200-BA LED is a reliable and cost effective solution for discrete LED indication. Its tunnel effect allows for a consistent and reliable indication in challenging indoor and outdoor applications, while still operating at low forward voltages and low currents. And its compact flange-type design makes it easy to install and maintain.
