SVEX-JXD Explosion-Proof Junction Box for Hazardous Area Security Systems
Explosion-proof junction box for Hazardous Locations
The Veilux SVEX-JXD is a heavy-duty explosion-proof junction box engineered for Class I Division 1, Class I Division 2, ATEX Zone 1, and ATEX Zone 2 classified areas. Built from 304 stainless steel (316L available), it provides a corrosion-resistant, IP68-sealed enclosure for routing and protecting explosion-proof conduit connections in oil and gas, chemical, mining, offshore, and pharmaceutical environments.
The SVEX-JXD serves as the central wiring hub in a complete explosion-proof surveillance system — connecting explosion-proof cameras, housings, monitors, and controller power feeds through a single certified enclosure. Four cable outlets accommodate explosion-proof cable glands and armored cable entry fittings for secure, sealed connections.

Frequently Asked Questions
What cable gland sizes does the SVEX-JXD accept?
The SVEX-JXD has 4 cable outlets sized for M20 and M25 explosion-proof cable glands. This accommodates most standard armored and explosion-proof conduit fittings. Consult Veilux for larger cable entries.
Can the SVEX-JXD be used in Class II (dust) locations?
The standard SVEX-JXD is rated for Class I (flammable gas) environments. For Class II (combustible dust) applications, please contact Veilux — a dust-ignition-proof enclosure with appropriate IP6X rating is required.
What is the difference between the 304 SS and 316L SS versions?
304 stainless steel provides good corrosion resistance for most onshore industrial environments. 316L stainless steel adds molybdenum for superior resistance to chloride-induced pitting corrosion — required for offshore platforms, coastal locations, and facilities with process chemicals containing halides.
How many cameras can be wired through one SVEX-JXD?
With 4 cable outlets, the SVEX-JXD can typically serve one camera housing with separate feeds for power, video, and control — or consolidate feeds from up to 4 peripheral devices in a zone wiring run. For larger junction requirements, see the SVEX-JB50 (6-port) or the SVEX-JXD4.
