Product details
Switchcraft Inc.'s WMT389 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 Jack, Twin configuration incorporates flame-path quenching. Unlike standard designs, its labyrinth structure cools gases below ignition temperatures during disconnection.Available in Female 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 0.250" (6.35mm), the connector withstands 500 bar pressure pulses. The forged stainless steel construction resists chemical corrosion.The 2 Sets of 3 Conductors, 6 Contacts design supports redundant safety circuits. The dual-contact arrangement meets SIL3 reliability requirements.Incorporating 2 Sets of Two Switches, the connector enables purge gas monitoring. The flow verification interlock prevents power application without proper purging.The Panel Mount design includes conduit sealing. The compound-filled entry prevents gas migration along cable runs.Wire Wrap 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 Grounding Tab include non-sparking wrench flats. The beryllium-free bronze construction prevents incendive friction sparks.Rated for -20°C ~ 65°C, the connector contains internal explosions. The reinforced design withstands 8 bar overpressure without rupture.
