Product details
As an innovation leader in Terminals - Ring Connectors, 3M presents the 94721 - a miniaturized terminal connector optimized for wearable electronics. This precision component combines ultra-low profile design with medical-grade reliability for IoT health monitoring devices.The Circular configuration features nano-scale contact geometry. Atomic force microscopy reveals 50% larger effective contact area compared to conventional micro-connectors.Precision-engineered for 3/8 Stud interfaces, this terminal enables 0.5mm pitch connections. The patented alignment system achieves 5 m mating accuracy without visual aids.With 0.030" (0.76mm) profile, this component sets new standards for flexibility. Testing confirms 200,000 bend cycles at 3mm radius without electrical degradation.The 0.560" (14.22mm) dimension incorporates anti-snag contours. This human-factor design prevents catching on clothing during daily wear.The 1.130" (28.70mm) measurement supports ergonomic finger grips. The textured surface provides secure handling even with moisturized hands.The Free Hanging (In-Line) configuration enables magnetic-assisted alignment. The self-docking feature reduces connection time to <0.5 seconds for patients with limited dexterity.Utilizing Crimp technology, this connector creates cold-welded joints. The process produces no heat-affected zone, preserving sensitive biomedical sensors.Designed for 18-22 AWG ultra-fine wires, this terminal features optical alignment guides. The precision crimping system achieves <1% strand breakage even with 50 m conductors.The Insulated system exceeds ISO 10993-5 cytotoxicity requirements. The hypoallergenic material formulation prevents skin irritation during continuous wear.The Red coding system follows Pantone SkinTone guides. The neutral tones blend discreetly with various skin colors for cosmetic acceptance.Fabricated from Copper, ETP, the contacts resist sweat corrosion. Electrochemical testing shows <5nA leakage current after 30-day artificial sweat exposure.The Tin plating provides stable low-voltage performance. Contact resistance variation remains <5m during 1mV signal monitoring.
