Treotham Automation igus ESD electrical chain safety modules

When there is motion, it can generate friction between machine parts and consequently static electricity may build up. At contact with an earthed body this can be discharged; potential differences of up to 10,000 V can occur. The current is usually relatively low, but sensitive electronic component parts can be irreparably damaged.

To avoid such damage, all components of a machine need to be discharging so the entire system needs to be earthed throughout. Permanent and reliable discharging of energy chains is especially important to avoid electrostatic build-up - even after years in use.

Electrostatic discharge is not only dangerous for electronic component parts - they can contribute to the combustion of burnable gases, dusts or vapours in areas with a danger of explosion. Wherever such conditions exist, for example in the chemical industry, material bulk handling or in coating lines, ESD energy chains contribute to avoid electrostatic discharges.

igumid ESD has been designed for applications where there are any electrostatic discharges that are potentially damaging; for instance, manufacturing or handling of sensitive electronic products and component parts. Made in conformity with ATEX guidelines for 94/9 EG for devices and systems in potentially explosive areas, these energy chains are certificated according to the EX II 2 GD classification, meaning ESD/ATEX energy chains from igus can be used in areas where gas or dust can cause the risk of explosion.
