From RS Pro, this range of LED indicators are sealed to IP67, meaning they are suitable for harsh environments. Compact and robust, the LED indicators have a chrome bezel and convenient solder tab terminals for ease of installation. These LED indicators offer a high degree of brightness, as well as low power consumption and long life. All models are highly reliable and excellent quality.

• 16mm coloured diffused lens
• 25mm dia. chrome bezel
• High brightness
• 2 negative terminals allow "daisy chaining"
• 0.11in. (2.8 x 0.8mm) terminals
• 22 dia. mounting hole size
• Operating Temperature: -25°C to +60°C
• Life Expectancy: 60000 Hours

For excellent performance, enhanced by a long life and low power consumption, then LED is the way forward. However, there are various other reasons to consider:

• Temperature - LED's give off a far cooler temperature than what an incandescent or neon light would.
• Direction - LED's will only emit light in a single direction, reducing the need for additional components, such as reflectors. Although this wouldn't apply if the LED indicator is being used as a circuit board signal.
• Cost - typically as LED's are in a larger supply than standard bulbs or pilot lights, they are a more cost effective solution to purchase, as well as run.

Each LED Indicator is rated at IP67. Although not fully waterproof, it is fully protected from dust and other small particles. It can also be fully immersed in water (up to 1 m depth) for a maximum of 30 minutes. It would depend on the application as to how this feature would be used, but the LED would continue to operate smoothly if the above guidelines are followed correctly.

Uses of LED indicators fall entirely down to the user. They can be fixed to PCB circuit boards and mounted on push buttons and switches. Primarily, these types of indicators are used within circuit boards and electronic designs. This is due to their relatively small size, as compared with other types of indicators, such as car turn signals.

It is recommended that the spare neutral is insulated if not used.
