Stock status andon display

Most of our andon systems are custom-made to suit users specific needs

An andon is literally a beacon - in its simplest form it can be a single LED which can be lit to indicate the state of something in your process.

More often, several andon indicators are combined, and are usually made with clusters of LEDs so that they can be clearly seen from a long distance.

This can form part of a powerful downtime-analysis system, which can match your process and give valuable returns on investment very quickly.
