ESD Maxi KLT containers

ESD Boxes

ESD KLT containers (Kleinladungsträger) are standardized transport and storage containers that comply with the VDA 4500 footprint grid, with surface resistances from 10⁵ to 10⁹ Ω measured per IEC 61340-5-1 - ensuring controlled electrostatic discharge at every handling step. The conductive or dissipative polymer construction provides a grounded path for stored components, keeping electrostatic voltages below the 100 V threshold required in EPA zones. Stacking loads of up to 50 kg and compatibility with standard KLT nest-and-stack lids make them directly integrable into automated conveyor systems including VarioFlow and TS-series transfer lines.

Our catalog currently offers 13 ESD KLT containers spanning the common VDA 4500 footprint sizes (300x200, 400x300, 600x400 mm) from leading manufacturers. All units are verified for full IEC 61340-5-1 and DIN EN 61340-5-2 compliance, with documented resistance test values supplied on request - ready for integration into certified EPA environments in electronics manufacturing, automotive logistics, and semiconductor handling.
