Main specifications
General information

Material

Glass-fibre reinforced polyamide based (PA) special conductive technopolymer, black colour, matte finish. 10³ Ω surface resistivity (ASTM D257 trial method), 10³ Ω·cm volume resistivity (ASTM D257 trial method).

Standard executions

BT-B: brass boss, threaded blind hole.
BT-FP: brass boss, threaded through hole.
BT-p: zinc-plated steel threaded stud, chamfered flat end according to UNI 947 : ISO 4753 (see Technical data).

Features and applications

The special conductive technopolymer (ESD-C Electrostatic Discharge Conductive) prevents the accumulation of electrostatic charge. 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 conductive feature according to EN 100015/1 and IEC 61340-5-1.
