Energy chain / drag chain
Qualified to ISO 14644-1 Class 1 for high-speed linear wafer stages, EFEMs and e-beam inspection carriers.
Product
Three-model ISO 14644-1 Class 1 cleanroom continuous-flex drag-chain series — SD 776 (unscreened), SD 780 C (overall copper-braided) and SD 787 C TP (twisted-pair copper-braided) — with low-outgassing TPE insulation and non-particulating PUR sheath.
Typical values for this cable type, based on ISO 14644-1 Class 1 / DIN VDE 0285 / UL AWM — confirmed in the datasheet and quotation for your order.
Application fit
Select SD 776 for unscreened 24 V I/O, SD 780 C for overall EMC-screened control, and SD 787 C TP for low-crosstalk differential RS-485/encoder pairs in ISO Class 1 cleanroom energy chains.
Qualified to ISO 14644-1 Class 1 for high-speed linear wafer stages, EFEMs and e-beam inspection carriers.
Ultra-low VOC/SVOC outgassing (ISO 14644-8) prevents molecular haze on lithography optics and silicon wafers.
Suitable for overhead cleanroom monorail (OHT / AMHS) hoist and shuttle loops.
SD 780 C 4G1.5/2.5 serves small cleanroom servo axes; for > 2.5 mm² 0.6/1 kV motors use Shielded Servo Motor Power Cable.
