Product details
CUI Devices's SP-3540B Barrel - Audio Connectors delivers military-grade reliability for harsh industrial environments. This ATEX/IECEx certified solution provides explosion-proof connectivity in oil refineries, chemical plants, and mining operations while preventing ignition risks.The Phone Plug configuration incorporates flame-path quenching. Unlike standard designs, its labyrinth structure cools gases below ignition temperatures during disconnection.Available in Male variants, the connector meets Zone 1 hazardous area requirements. The increased safety (Ex e) design prevents spark generation.With Stereo (4 Conductor, TRRS) architecture, the interface handles 4-20mA intrinsically safe signals. The energy-limiting design maintains <30V/<100mA under fault conditions.The 3.50mm (0.141", 1/8", Mini Plug) - Headphone complies with IEC 60079-0 standards. The anti-static housing prevents dangerous charge accumulation.Precision-engineered to 0.126" (3.20mm), the connector withstands 500 bar pressure pulses. The forged stainless steel construction resists chemical corrosion.The 4 Conductors, 4 Contacts design supports redundant safety circuits. The dual-contact arrangement meets SIL3 reliability requirements.Incorporating Does Not Contain Switch, the connector enables purge gas monitoring. The flow verification interlock prevents power application without proper purging.The Free Hanging (In-Line) design includes conduit sealing. The compound-filled entry prevents gas migration along cable runs.Solder method utilizes explosion-proof crimping. The spark-free tooling meets MSHA approval for coal mine applications.Featuring Unshielded with conductive gaskets, the connector maintains ground continuity. The 360 shielding contact prevents RF gaps in hazardous areas.The Cover, Strain Relief include non-sparking wrench flats. The beryllium-free bronze construction prevents incendive friction sparks.Black options meet hazardous area identification standards. The high-visibility yellow housing indicates explosion-proof rating.Rated for -25°C ~ 70°C, the connector contains internal explosions. The reinforced design withstands 8 bar overpressure without rupture.
