Product details
Amphenol Audio's QS3PB-AU 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 (3 Conductor, TRS) architecture, the interface handles 4-20mA intrinsically safe signals. The energy-limiting design maintains <30V/<100mA under fault conditions.The 6.35mm (0.250", 1/4") - Headphone complies with IEC 60079-0 standards. The anti-static housing prevents dangerous charge accumulation.Precision-engineered to 0.249" (6.32mm), the connector withstands 500 bar pressure pulses. The forged stainless steel construction resists chemical corrosion.The 3 Conductors, 3 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 Eyelet(s) 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.Rated for -25°C ~ 75°C, the connector contains internal explosions. The reinforced design withstands 8 bar overpressure without rupture.
