QCI 2-250

The QCI 2-250 by 3M is a cutting-edge Terminals - Wire Splice Connectors solution designed for precision instrumentation and medical equipment. This ultra-reliable connector ensures flawless signal transmission in sensitive measurement systems, where even minor interference can compromise diagnostic accuracy.Featuring Shearbolt technology, this connector achieves contact resistances below 0.5m , critical for microvolt-level signal acquisition. When implemented in ECG monitoring systems, it reduces noise artifacts by 60% compared to standard medical connectors.With 2 access channels, this terminal supports high-density wiring in portable medical devices. Its patented strain relief system prevents wire fatigue during repeated sterilization cycles.The Screw method employs medical-grade alloys that resist disinfectant chemicals. Testing per ISO 10993-5 confirms biocompatibility for prolonged skin contact applications.Compatible with 250MCM (kcmil)-2 AWG conductors, this solution accommodates both flexible patient leads and rigid equipment wiring. The precision crimp zones maintain consistent pressure without damaging fine wire strands.Non-Insulated materials exceed UL94 V-0 flammability ratings while remaining flexible at -20 C. The proprietary compound prevents plasticizer migration that could degrade sensitive electronics.
