neon electrodes

EGL electrodes have consistently raised the industry standards for reliability and performance since their introduction in 1930.To ensure rigid quality control, all phases of manufacturing are performed in-house, including emission coating, inverter welding shells with lead wires, and sealing and centering the mounts in glass envelopes.

Today, EGL manufactures over 25 standard and custom electrodes – the world’s broadest line – to satisfy your most specialized requirement without compromise.

The latest addition to the growing family of EGL electrodes is the “ADVANTAGE™” electrode series, combining the features you need for the ultimate in brilliance, clarity, and longevity.

All EGL electrodes are made in the USA and are readily available from your local distributor.

12CMOur smallest ceramic collar electrode designed for use on 8 – 12mm neon tubing. Neon tubing must not exceed 8 feet and consideration to the electrode size must be exercised during processing. This e lectrode is rated to operate at 30mA maximum current. Correct processing levels must be monitored with a Milliamp Meter and Torr or Positive Pressure Gauge.
12CLThis electrode is designed for use on 12 – 13mm neon tubing. It is rated for operation on 30 – 45mA transformers and has a longer shell for use on Accuwall classic tubing and units that may require higher current levels during processing. We suggest the use of 12CM electrodes on smaller diameter units of 8 – 10mm tubing.
15CMOur most popular electrode for use in housings or where short returns are used. It is rated for operation on 30 – 45mA transformers and can be used on neon units up to 10 feet long provided processing is monitored with all necessary gauges. Since it has a 500mA processing level, this electrode can also be used on smaller dia meters of tubing.
15CLThis electrode can be used on all 15mm neon tubes and is rated for use on transformer up to 80mA. It can be ordered in 2 different glass sleeve lengths (2.625 & 2.875 inches). It is not recommended for use on tubing diameters smaller than 15mm due to the high processing current required to fully process the shell. This electrode has successfully outperformed all electrode life tests against our competitors. This shell construction requires full system gauges when processing for best results to insure all recommended levels are achieved and vacuum levels during bombardment are monitored to insure shells are evenly processed.
19CMThis cold cathode electrode operates on 120 – 180mA transformers. It is designed for use on 18 – 25mm cold cathode tubing and must not be used on smaller diameters. It requires a bombarder 15KVA or larger to properly heat the shells and glass during production. System requirements and performance must be met before attempting cold cathode production.
19CLThis cold cathode electrode operates on up to 200mA transformers and has a longer shell than the 19CM. Again it requires a larger bombarder, 15KVA or larger and system requirements must be met before attempting cold cathode production.
