HEAT SHRINK TUBING FOR AUTOMOTIVE APPLICATIONS TE AUTOMOTIVE /// WHITE PAPER 10 HTAT • Low profile mechanical protection, strain relief and sealing • Seals a wide range or different number/gauge sizes of wires into the same connector housing • Semi-flexible, dual-wall moisture proof • Environmental sealing • Ideal for connector sealing covering large diameter differences • High strength bonding Connector 2 to way 18 connectors are frequently used on cars, often in wet and high temperature areas such as engine compartments. Manufacturers need simple, versatile sealing systems with a minimum number of components that provide connector sealing even when not all of the contact cavities are in use. Sealing Application Challenge facing Products: Application Tooling manufacturers Features + Benefits IR-1891 Shuttle Machine • Automatic cycle start once heater is manually positioned over product, which gives improved process control (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 assem- blies give increased process rates • Cooling fan above each fixture assembly maintains holding fixture at an acceptable tempera- ture • Compliant with latest CE and RoHs requirements Model 105 • Closed-loop speed and tempera- ture control • Continuous controlled process • Adaptable for different applications • CE approved • Heater operation and over- temperature alarm lights Ring Terminal Maintaining the electrical quality of ring terminal connections has always been critical. In today's cars it is even more important as manufacturers are increasingly using ring terminals to ground low current 'quiet' and 'logic' signal circuits. Any increase in resistance, usually caused by corrosion as a result of moisture entering the wire terminal connec- tion, can critically impair these electrically sensitive circuits. Mechanical damage can also reduce electrical performance, so protection during handling is import- ant, as well as effective strain relief when in use.
