890-242

The 890-242 by WAGO Corporation redefines Terminal Blocks - Headers, Plugs and Sockets performance for medical imaging equipment. This precision-engineered interconnect solution delivers exceptional signal fidelity in MRI and CT scanner applications while meeting stringent medical safety standards. The Terminal Blocks - Headers, Plugs and Sockets ensures reliable operation in life-critical diagnostic systems.Featuring Plug, Female Sockets construction, this component achieves ultra-low noise characteristics essential for sensitive analog signals. The shielded design provides 60dB better EMI rejection than standard medical connectors.Available in 2 positions, the modular architecture supports high-density sensor arrays. The symmetrical layout maintains impedance matching across all channels for accurate signal acquisition.With 2 positions per level, the optimized configuration minimizes crosstalk between adjacent analog and digital lines. This arrangement is critical for maintaining signal integrity in multi-channel medical devices.The 1 stacking option enables three-dimensional packaging in space-constrained medical equipment. Vertical integration reduces cable clutter while maintaining proper isolation distances.The 0.173" (4.40mm) pitch spacing exceeds medical isolation requirements for patient-connected equipment. The reinforced dielectric barriers prevent leakage currents in defibrillator-proof designs.180° entry geometry facilitates sterile field cable management. The smooth surfaces allow for easy cleaning and disinfection in surgical environments.Utilizing Screwless - Push-In Spring termination, the system ensures gas-tight connections for implantable devices. The hermetic sealing prevents fluid ingress in sterilization cycles.The Free Hanging (In-Line) mounting complies with IEC 60601-1 standards for medical equipment. The secure latching mechanism prevents accidental disconnection during patient transport.Meeting 16A IEC standards, the design accommodates microcurrent measurements. The gold-plated contacts ensure stable readings below 1 A resolution.The 250 V certification includes testing for defibrillation pulses. The insulation system withstands 5kV transients without breakdown.Rated for 14 A leakage current, the design meets Class BF equipment requirements. The ultra-pure contact materials prevent electrochemical migration.With 600 V patient isolation rating, the insulation system exceeds 2x MOPP requirements. The material selection prevents dielectric absorption in humid environments.Compatible with 16-22 AWG medical-grade cables, the termination system maintains consistent contact force. The strain relief design prevents conductor fatigue during repeated flexing.The Gray housing uses medically approved pigments that withstand gamma radiation sterilization. The high-visibility colors enhance error-proofing in emergency situations.Operating across -35°C ~ 85°C range, the materials maintain flexibility in cryogenic applications. The design has been validated for liquid nitrogen exposure in MRI systems.The Locking Feature include integrated safety interlocks for medical devices. These prevent hazardous exposure during equipment servicing while allowing quick disconnection in emergencies.
