RAST 2.5 IMS Direct Connectors for Aluminum Circuit Boards co mi ng so on RAST 2.5 IMS [direct connectors for Aluminum-PCBs] Automotive electronics increasingly require the heat produced from electronic components to be dissipated in order to improve the life and functionality of modern parts. Especially highpower LEDs for vehicle headlights demand an optimized heat management for tight installation spaces. Insulated Metal Substrate (IMS) is used more and more for printed circuit boards, with aluminum being the primary thermoconductive substrate to which dielectric and copper traces are applied. As a pioneer in the field of RAST connectors we have developed a direct connector that secures the safe single-sided mating with an aluminum PCB edge. Its mating face is based on the versatile 2.5 RAST connectors which can be processed on fullyautomatic harnessing equipment and whose proven record sees it used in millions of vehicles. 2 Insulation displacemet technology (IDT) Keying to avoid mismating RAST 2.5 IMS Locking options For signal and load currents up to 6 A According to automotive standards 351050 · 351550 · 352150 TEMPERATURE RANGE -40 °C/+130 °C MATERIALS Insulating body 35...50 PBT, V0 according to UL 94 Insulating body 35...50 M12 PA, V2 according to UL 94 Contact spring 35...50 (M...)V102 CuSn, pre-nickel and gold-plated MECHANICAL DATA Insertion force/contact ≤ 4.0 N Withdrawal force/contact ≥ 0.5 N Retaining force/lock ≥ 6.0 N Mating with IMS printed circuit board 1.5 mm, 352150 with guide frame 3500 CONNECTABLE CONDUCTORS INSULATION DISPLACEMENT TERMINAL Section 0.22–0.38 mm2 Insulation diameter ≤ 1.6 mm ELECTRICAL DATA Contact resistance ≤ 5 mΩ Rated current 4 A (according to derating curve) Rated voltage 32 V AC Material group IIIa (IEC)/2 (UL) (CTI ≥ 250) Creepage distance 0.6 mm Clearance 0.22 mm (mated on IMS) Insulation resistance > 1 GΩ Detailed information: lumberg.com 3 136822 · 1410-0.5 · EN www.lumberg.com · [email protected]
