HEAT SHRINK TUBING FOR AUTOMOTIVE APPLICATIONS TE AUTOMOTIVE /// WHITE PAPER 7 CRN • Excellent abrasion resistance • Outstanding physical and electrical performance • Excellent chemical and solvent resistance • Good strain relief performance Connectors Heavy gauge power distribution cables used in cars are typically long and heavy and can be difficult to work with. Many of these cables have to accommodate tight radius bends and other shapes to fit in crowded underbonnet areas. Products offering strain relief are required in these applications. For wet and high temperature areas such as engine compartments manufacturers need simple, versatile sealing systems with a minimum number of components. Strain Relief Application Challenge facing manufacturers Products: Features + Benefits Application Tooling IR-1891 Shuttle Machine • Automatic cycle start once heater is manually positioned over product, which gives improved process con- trol (recommended for adhesive lined heat shrinkable tubing e.g. sealing applications) • Automatic heating head retraction at end of cycle prevents damage to components • Multiple product fixture assemblies give increased process rates • Cooling fan above each fixture assembly maintains holding fixture at an acceptable temperature • Compliant with latest CE and RoHs requirements HTAT • Low profile mechanical protection, strain relief and sealing • Semi-flexible, dual-wall moisture proof • High strength bonding RPPM • Single component solution - to insulate and protect almost all dry area splices • Low profile protection - reducing diameter of conduit required • Flexible while providing superior strain relief than PVC tape • Rapid installation • Repeatable process • High shrink ratio - allow one size to cover a wide range of splice combinations In-line Splices All electrical splices in a wiring harness need to be insulated and protected from mechanical abuse. Effective protection is becoming even more critical as ultrasonic welding is increasingly being used to make the electrical connection. Ultrasonic welding, while providing a much better electrical connection than traditional crimping, is mechanically weak, especially in peel and tear, so additional mechanical protection and strain relief must be provided. +135° C -55° C 2:1 +135° C +125° C -55° C 4:1 +110° C Miniature Splices Following the trend to reduce cost, weight and space, wire is being replaced by smaller cross-sections and the splices are particularly fragile requiring mechanical protection and strain relief. Given the very low profile of these splices, the use of conventional PVC tapes might become an increasingly unsatisfactory solution. QSZH • Adhesive liner that melts to provide strong mechanical bond • Mechanical protection against flexing, abrasion and cut-through • Small cross-sectional profile • Quick installation • Zero halogen +85° C -40° C 4:1 +80° C +125° C -40° C 4:1 +135° C RBK-ILS Processor MKIII • Long life heating elements • Installation parameters and product size information (individual selec- tion) • Operator key lock / password protection levels • Automatic heater retraction on mains failure (updated safety feature) • Automatic calibration (single cycle) • RS232 interface to receive informa- tion for the next installation from an ultrasonic welding tool • Pre-installed connection for an optional air-cooling-device • Signal output "0" volt (n/c and n/o) which can be send to a server, local PC or customer intranet • Machine hours and installation cycle counters • Software upgradeable to support special applications • Integrated SW-safety-features to provide safeness during processing • Compliant with latest CE and RoHs requirements
