Electrical/Electronic Architecture

Delphi's 1.5 and 2.8 mm Block-sealed Terminal Systems (BTS) are complete, high-performance connection systems including terminal, seal, and connector. BTS brings to the market a creative layered-seal concept for connectors, utilizing two independent sealing layers in a patented process that offers advantages over traditional single-piece block-sealed tool technology. This innovative layered-seal technology allows the connector to engage/disengage up to four times and still retain sealing performance.

The BTS tangless terminal is an innovative clean body, two-piece design (base part with steel sleeve). It provides higher electrical performance including higher levels of temperature- and vibration-resistance. The terminal allows a broader range of cable sizes over competitive offerings.

Benefits

• Two-piece terminal design (base part with steel sleeve) allows an optimized design for electrical and mechanical requirements
• Dual locks provide greater integrity with more robust electrical performance
• Double-sided tangless primary lock
• Secondary lock shoulders
• Clean body design is possible for layered- and block-sealed system
• Layered- and block-sealed design configurations allow small centerline spacing and help improve packaging capability
• Single wire seal versions for BTS 280 enable mixed block seal and single wire seal and help improve packaging capability
• Layered-seal design offers two independent sealing layers for low insertion force and high sealing class performance
• Terminal can be engaged/disengaged four times through the seal and still retain sealing performance
• Superior performance in demanding application environments due to excellent temperature and vibration resistance
• Broad range of cable sizes for enhanced application flexibility
• High strength copper alloy base material helps improve connectivity, performance, and robustness
