NEW Cost-Effective Termination Solutions for Copper & Aluminum Magnet Wire

admin2 — Wed, 21 Apr 2010 18:39:28 +0000

An insulation displacement crimp (IDC) interconnection system that offers a cost-effective interconnect for fractional horsepower (FHP) motor manufacturers. The product drives cost reduction, as the same part number qualifies for termination of both copper and aluminum magnet wires. Two IDC slots provide four gas-tight points of contact. These connectors can terminate two magnet wires of the same size in one terminal, and accommodates wire sizes ranging from 34 AWG to 12 AWG for maximum flexibility. Multiple plating options make these terminals very versatile. Applications include: motor windings, coil & bobbin connections, transformer windings, and lighting ballasts. For samples or more information, please send an email to EngHelpDesk@dee-inc.com. Dee can support all of your termination solutions.
