Features and applications

The special conductive technopolymer (ESD-C Electrostatic Discharge Conductive) prevents the transfer of electrostatic discharge between bodies with different electric potential. BT-ESD knobs are suitable for ESD PROTECTED AREA (EPA) where components which are susceptible to electrostatic discharges are to be handled with the minimum risk of damage. The indelibly printed mark (ESD-C) on the surface of the knob identifies the particular antistatic feature according to EN 100015/1 and IEC 61340-5-1. <BR>


Polyamide based (PA) special antistatic technopolymer. Resistant to solvents, oils, greases and other chemical agents.
