Product details
CUI Devices's SJ2-254A-SMT-TR represents the next evolution in Barrel - Audio Connectors technology, optimized for mission-critical audio applications. This connector series combines military-grade durability with audiophile-grade signal purity, making it ideal for aerospace, defense, and studio recording environments.The Phone Jack implementation provides galvanic isolation between channels. Differential signaling capability reduces common-mode noise by 30dB compared to conventional designs.Female options allow customized gender configurations per channel. The hermaphroditic contact design enables unique mixed-gender panel layouts.Supporting Stereo (4 Conductor, TRRS) topology, the connector handles AES3 digital audio protocols. Impedance-matched traces maintain 110 characteristic impedance 5%.Compliant with 2.50mm (0.094", 3/32", Sub Mini, Miniature) - Headphone specifications, the connector interfaces with NATO STANAG 3910 systems. The flared entry design enables blind mating in low-visibility conditions.The 0.102" (2.60mm) dimensions incorporate strain relief features. Kevlar-reinforced jacket withstands 50N cable pull force without deformation.4 Conductors, 4 Contacts arrangement supports MADI (AES10) multiplexed audio. Contact spacing prevents arcing at 250Vrms working voltage.The Does Not Contain Switch configuration enables hot-plug capability. Arc suppression circuitry protects contacts during live insertion.Designed for Surface Mount, Right Angle installation, the connector features anti-tamper fasteners. Conformal coating compatibility prevents moisture ingress in marine applications.Solder process utilizes lead-free solder alloys. The gas-tight connection meets NASA outgassing specifications (<1% TML).With Unshielded effectiveness of 90dB at 1GHz, the connector exceeds TEMPEST requirements. The triple-layer shielding includes copper tape, braid, and ferrite beads.The Board Guide package includes corrosion-resistant plating. Salt spray testing confirms 500 hours resistance per ASTM B117.Operational across -25°C ~ 85°C range, the connector survives 50G mechanical shock. Vibration resistance meets MIL-STD-810H Method 514.8.
