Product families
An offering organised by application
From connections to instrumentation, each family must be selected by checking the zone, substance, group, temperature class and required protection level.
Lighting and signalling
Lighting fixtures, audible and visual signalling devices and emergency equipment for classified areas.
Enclosures and control
Ex d, Ex e and Ex ia enclosures, control stations and accessories in aluminium, stainless steel or composite material.
Industrial cables
Control and instrumentation cables, including intrinsically safe circuits, designed for harsh environmental conditions.
Cable protection and routing
Flexible or rigid conduits, trays, supports and protection systems for cable routing.
Explosion-protected cable glands
Solutions for armoured and unarmoured cables, barrier versions and materials suitable for corrosive environments.
Sockets, plugs and connectors
Power and signal connections for equipment installed in areas with an explosion hazard.
Field instrumentation
Sensors, limit switches, pressure switches, thermostats and encoders selected for the zone and application.
Automation and power transmission
Interfaces, barriers, panel PCs, motors, gearboxes and pneumatic components in the available certified versions.
Quick guidance
Understand the zone classification
Select a zone to view its meaning and general guidance. This information is indicative, does not recommend products and does not replace area classification.
Zone 1 - Gas
An explosive atmosphere consisting of gas, vapour or mist may occur occasionally during normal operation.
Check the type of protection, gas group, temperature class and environmental conditions of the installation.
- Atmosphere
- Gas, vapour or mist
- Indicative category
- 2G o superiore
- Indicative EPL
- Gb o superiore
General guidance only: always verify area classification, complete marking, certificate, substance, temperature, installation and destination-market requirements.

Frequently asked questions
Before selecting an ATEX component
What information is needed to start?
At least the classified zone, presence of gas or dust, substance group, temperature class, environmental conditions and required function.
Are ATEX and IECEx equivalent?
They are different schemes. The required compliance depends on the destination market and the specific installation.
Do all the product families shown have the same certifications?
No. Certifications, versions and operating limits vary by series, configuration and manufacturer and must be checked against the relevant certificate.
Does Direma perform certification?
Direma supports the selection and supply of certified products. Certification is declared by the manufacturer and the relevant notified bodies.
