3421-7620

3M's 3421-7620 offers cutting-edge solutions in Rectangular Connectors - Free Hanging, Panel Mount, specifically designed for medical equipment requiring reliable signal transmission. This precision connector system meets IEC 60601-1 safety standards while delivering exceptional performance in diagnostic imaging, patient monitoring, and surgical robotics applications.The Receptacle configuration features a unique breakaway design for patient safety. The low-force disconnection mechanism prevents equipment damage during emergency situations.Utilizing Female Socket technology, these medical-grade contacts eliminate the risk of signal artifacts. The redundant contact design ensures continuous monitoring during patient movement.Available in 20 contact arrangements, the connector supports both analog biosignals and digital data streams. The isolated contact groups prevent cross-talk between sensitive measurement channels.The {PartNumber}'s 0.100" (2.54mm) spacing provides optimal balance between high-density packaging and electrical isolation. This configuration meets the 8mm creepage requirements for medical applications.The 2 row matrix incorporates shielding between sensitive signal paths. This layout is particularly effective for EEG and EMG signal acquisition systems.0.100" (2.54mm) inter-row distance minimizes capacitive coupling between measurement channels. This spacing is essential for high-impedance ECG electrode connections.The Free Hanging (In-Line) design includes smooth surfaces for easy cleaning and disinfection. The seamless housing prevents bacterial growth in clinical environments.The IDC method ensures gas-tight connections that withstand repeated sterilization cycles. The medical-grade materials resist degradation from chemical disinfectants.Compatible with Ribbon Cable medical cables, the connector maintains flexibility after repeated flexing. The strain relief system prevents cable damage at the termination point.Supporting 26-28 AWG medical cables, the contacts maintain signal integrity for microvolt-level biosignals. The precision crimp profile preserves the cable's twisted pair geometry.The Closed End, Polarizing Key, Strain Relief include integrated RF shielding for sensitive measurement circuits. These features are critical for maintaining signal accuracy in MRI environments.The Gold plating exceeds ISO 10993 biocompatibility requirements. The hypoallergenic surface treatment prevents skin irritation in wearable medical devices.With 30.0µin (0.76µm) plating, the contacts maintain stable impedance for precision measurements. The ultra-smooth surface finish reduces contact noise to sub-microvolt levels.The Gray housing incorporates radiopaque markers for X-ray visibility. The high-contrast color options aid in quick identification during medical procedures.
