Product details
LEMO's ERA.3E.250.KTL redefines reliability standards in Coaxial Connectors (RF) connectivity solutions. Developed for aerospace-grade signal integrity, this connector maintains phase coherence across extended temperature cycles while minimizing skin effect losses.The Coaxial interface configuration delivers consistent 50 characteristic impedance, critical for high-speed digital RF systems. Its elliptical contact design reduces surface wave propagation.Utilizing Receptacle, Female Socket architecture, the connector achieves >65dB isolation between adjacent ports. The tri-material contact system prevents fretting corrosion.Solder Cup methodology ensures gas-tight connections with <0.1pF parasitic capacitance. The crimp profile is optimized for {Cable Group} dielectric compression.With Solder technology, the connector exhibits <2nH grounding inductance. The quad-segment shielding provides omni-directional EMI suppression.The 50Ohm matched design features tapered dielectric transitions to minimize return loss. Time-domain reflectometry shows <3% impedance deviation across {Frequency - Max} bandwidth.The Panel Mount configuration integrates strain relief that exceeds ICE 60332-1-2 flame ratings. The captive hardware prevents loose parts in vibration environments.Engineered with Bulkhead - Rear Side Nut, the connector withstands 50G mechanical shock per MIL-STD-202H. The captive hardware eliminates installation tool requirements.Tested with RG-11A, 115A, 144, 165, 213 specifications, the connector maintains <0.05dB variation during 10,000 flex cycles. The anti-kink design preserves cable phase stability.Push-Pull engagement system provides audible mating confirmation with <1.5N engagement force. The anti-decoupling mechanism prevents spontaneous disconnection.The 1 configuration features individual port identification for automated testing systems. Each channel maintains <-60dB cross-port isolation.Black coding follows NATO STANAG 3910 specifications for rapid visual identification. The ceramic-loaded composite resists UV degradation.Meeting IP68 - Dust Tight, Waterproof standards, the connector survives 1000hr humidity aging per IEC 60068-2-78. The hydrophobic seals prevent capillary water ingress.The Beryllium Copper formulation provides <0.5 in surface roughness for consistent RF performance. Material properties are verified per ASTM B36 standards.
