spiral coil 7-pole type-S Accesoire with vulcanized plugs 4.5 meter long
| Description | This 7-pole spiral cable for 24V systems is sold per unit and has a working length of 4.5 metres. Both ends are fitted with vulcanised connectors compliant with ISO 3731, the international standard for 7-pole electrical connections on trucks and trailers. Vulcanised connectors are bonded directly to the cable ends during the manufacturing process, producing a watertight and mechanically robust seal between connector and cable that resists the ingress of moisture, dust, and contamination. This makes the cable particularly suitable for outdoor use and heavy transport applications where the connection is subject to continuous mechanical load and weather exposure. The Type-S configuration under ISO 3731 defines the pin assignment for truck-trailer connections in the 24V segment, covering indicators, brake lights, tail lights, and other lighting circuits. The 4.5-metre working length provides ample slack for the cable loop between tractor and semi-trailer when cornering, preventing the cable from coming under tension. The spiral construction ensures controlled retraction when the trailer is running straight behind the towing vehicle. |
