Quick Installation

For OEMs, efficiencies in production and assembly can take place in a variety of ways. 

Quick installation of the PMI, light pipe or other components can occur with features including quick-connect tabs, connectors, or press-fit options.

Quick-Connect Tabs

PMIs can be connected to the power source within the device by wire leads or quick-connect tabs (or terminals) that use metal to conduct electricity and power the device. 

While slightly more expensive than wire leads, quick connect tabs provide greater flexibility in production and assembly.

Refractive Index

When light shines through a medium like acrylic, the ray of light shifts before the exit point due to a phenomenon called refraction.  

To ensure the ray shines where intended, the Refractive Index measures how much of a light ray gets bent when it hits the medium and is factored into the design.

Resistant to Shock and Vibration

Many applications can put undue strain on a device due to electric shocks or vibration. 

Fortunately, there are tactics to help ensure an indicator is resistant to these harmful forces, such as double-D mounting style, hex nuts, lock washers, and O-ring gaskets.

Resistor

A resistor is a component that helps regulate and limit the electrical current that goes through a device. In some products, it’s optional, in others, it’s included.

Be sure to view the specs on the manufacturer’s product datasheet. Resistors can also be customized for a range of indicator needs.

Retainer

A retainer is an additional accessory used to secure a light pipe in place or provide added level of protection from dust, moisture or vibration.

Right-Angle Light Pipe

Some LEDs require 90-degree alignment to the light pipe. Those situations are where a right-angle light pipe is mounted directly to the PCB board directly over the LED. These rigid light pipes are available in multiple board-mount configurations, including 1-, 2-, 3-, and 4-position options.

Right-Angle Surface-Mount LED

An LED that is mounted to the HMI or panel that requires a 90-degree alignment with the light pipe. 

Flexible right-angle light pipes are a good fit for right-angle surface-mount LEDs, as they are affixed to the PC board.

Right-Angle Through-Hole LED

An LED designed to be affixed to the PC board using two prongs that requires 90-degree alignment. 

Devices with wave solder circuit boards are ideal for right-angle through-hole LEDs.

Rigid Light Pipe

A ruggedized light pipe includes additional features or components that make it more suitable for tough working conditions, such as high-humidity, moisture, or vibration.

Ruggedized Indicators

When the working conditions are harsh due to weather, moisture or vibration, ruggedized indicators are those that use additional accessories or design features to help them provide reliable operation in bad working environments.
