PCB terminal blocks with Ex approval for increased safety

Choose between plug-in and non-plug-in solutions. In addition, the plug-in connector PCB terminal blocks and headers are designed for wave soldering processes.

The following options for connecting the conductors ensure the necessary flexibility:

Screw connection
Push-in connection
Spring-cage connection

Explosion hazard!

Explosions can occur when combustible materials, oxygen, and sources of ignition meet.

Highest priority is afforded to the safety of individuals, machines, and buildings and the protection of the environment. The prevention of explosions also plays an important role. Explosions can occur when oxygen, a combustible material, and a source of combustion meet.

The products have component approval according to the IEC/EN 60079-0 and IEC/EN 60079-7 standards, which define the requirements for devices in potentially explosive atmospheres.
