ISO 13990-3:2006 PDF

Overview

ISO 13990-3:2006 - Textile machinery and accessories - Yarn feeders and yarn control for knitting machines - Part 3: Dimensions for connecting and interconnection cables - defines dimensional requirements for multi‑wire connecting cables and interconnection cables used in the low‑voltage electrical installations of yarn feeders and yarn control devices. The standard ensures mechanical fit, reliable electrical contact and interoperability between cables, cable conduits and contact strips on knitting machine accessories.

Key topics and requirements

• Scope: Applies to multi‑core, low‑voltage connecting and interconnection cables for yarn feeders and yarn control devices in knitting machines.
• Dimensional specifications: Provides precise external dimensions, core spacing and tolerances for connecting cables (two‑ to five‑core variants) to ensure correct seating in cable conduits and trouble‑free electrical contact.
• Interconnection cable geometry: Specifies interface dimensions between connecting cable surfaces and contact surfaces - including allowable distances and widths (examples in the standard: contact distance range 1.5–3 mm; mid‑contact reference 9.5 ± 0.5 mm; width limits for cable contact surface
