Explosion Proof & I.S. Coaxial/RF Barrier Coupler Fitting with Surge Protection (SX Series)



Atex, IECEx, INMETRO and USA&Canada apparatus approved


All required circutry is recessed into fitting and encapsulated
against harsh environments


High pressure tested sealing


Electrostatic sourge protection circuit


Solexy’s patented (7,057,577) Explosion-Proof Antenna Coupler permits the installation of non-Ex certified antenna in hazardous areas.
This coupler is designed to be used directly with listed explosion proof housings or conduit fittings.

An integrated blocking circuit prevents hazardous energy reaching the antenna if a radio, modem or access point failure occures. It also allows for antenna removal in hazardous areas.

The coupler’s robust design allows for connection to practically any radio and antenna. It is a highly flexible and cost effective solution to hazardous area radio system deployment. The coupler can also be used as a cable bulkhead.

Fitting is approved for hazardous locations and can be installed with a simple wrench.

Short Circuit Protection

Includes integrated blocking circuitry.


An integrated surge protection circuit, according to IEC61643-21 Category C2, protects the radio from potential surges (patent pending).

Environmental Protection

Fitting 300 series stainless steel construction and integral potting protects electronics from corrosive environments.


The SX Series is certified Atex, IECEx, INMETRO and for North America as an apparatus, and can be installed per the conditions of acceptability, without further assessment. North America approval (USA&Canada) includes class & divisions and zones. IECEx certification is issued from an Australian notified body, therefore SX can be installed in Queensland mines.

No Sealing Fitting Required

Permits a wide variety of passive antennas to be installed in hazardous areas. Antennas may be removed and/or installed with power on. Perfect for a cable bulkhead connection.
