Ex system

PMA Ex system for hazardous areas – Providing comprehensive protection for cables, wires, and hoses. This system guards against mechanical damage, UV radiation, weathering, and chemicals.
– Products made of specially modified, load discharging polyamide materials (PA12) for use in explosion endangered zones 1/2 (gas) and 21/22 (dust)
– Identical in function to the standard product range PMAFIX/ PMAFLEX (since more than 40 years successfully used in applications as railway, machinery, automation, etc.)
– Sealing system fulfilling IP66, IP68
– System safety: For security reasons re-opening is only possible with the use of a screwdriver
– Flexible conduits, excellent for applications with continual reversed bending
– Quick and simple installation, reduced total installation costs (compared to other explosion-proof cable protection systems)
– No corrosion, long service life

EMC System solutions

Reliable shielding – This product line features metal braids made of tin-plated copper and hybrid braids composed of tin-plated copper wires mixed with polyester monofilament. Fittings made from nickel-plated aluminum or nickel-plated brass. These braids provide protection against electromagnetic interferences.
Fittings ensure secure clamping of the braid, and a robust connection between the shielding braid and the conduit system.
The trusted EMC System from PMA provides high-grade shielding to protect against electromagnetic radiation while also offering mechanical cable protection.
