PanelMax™ Shielded Wiring Duct and Noise Shield route, separate, and shield
sensitive wiring from noise emission. This allows pathways to be placed in
closer proximity, saving valuable space within industrial control panels. The
shielding provides up to 20dB reduction in noise (EMI/RFI), or 90% noise
voltage reduction (NVR), which is equivalent to 6 inches of air spacing
between sensitive and noise-emitting wiring.* **
Several wire routing and segregation configurations are possible with the
innovative Shielded Wiring Duct and Noise Shield, delivering greater
design flexibility to satisfy a wide range of applications.
These products are part of the broad range of reliable product systems
offered by the Panduit Industrial Automation Solution. These product
systems aid in reducing design and assembly time, create valuable panel
space savings, and provide easier installation and maintenance.

Key Features Benefits
Metal noise barrier* **^‡ Reduces EMI/RFI noise between sensitive and noisy wiring for up to 20dB reduction
in noise, or 90% NVR (equivalent to 6 inches of air spacing); innovative design installs
easily within Panduit wiring duct or when mounted separately, delivering greater design
flexibility to satisfy a wide range of applications
Bonding clip ^
Segmented design Speeds installation by allowing section(s) of the shield to be cut and snapped off at
intervals to easily size shield to length, with minimal deburring
Vertical wall slots Allow wires to cross the barrier at 90° when necessary, providing greater design flexibility
Horizontal cable tie slots Allow wire bundles to be held in place using cable ties to optimize cable management
and aesthetics
Zinc-plated steel and durable
black powder-coated surfaces
Durable powder-coated vertical surfaces for smooth edges; uncoated, corrosion
resistant, zinc-plated surface in shield contact area with sub-panel, ensures continuity
for proper bond to ground
When installing the shield inside a wiring duct, the bonding clip maintains electrical
continuity between the panel and shield for optimal noise mitigation and aesthetics

*Recommendations for distance separation between noisy and low-noise zones are referenced in IEEE 1100 Emerald Book, Recommended Practice for Powering and Grounding
Electronic Equipment. Consult the component manufacturer for specific wire segregation distance requirements.
**PanelMax™ Shielded Wiring Duct and Noise Shield deliver approximately 20dB of noise reduction across common industrial noise frequencies at 30mm wire separation
with an approximate 1 meter coupling length.
^The shielded wiring duct or noise shield, bonding clip (if used) and enclosure must be electrically bonded to ground for the shield to be effective (see Panduit installation
instructions EP001, for shielded wiring duct or RW260, for noise shield).
