The Panduit CMHDMIIW is a Mini-Com™ series HDMI 2.0 Type A female-to-female coupler module designed to integrate into Panduit Mini-Com faceplates and surface-mount boxes. If you're running HDMI infrastructure through structured cabling in conference rooms, classrooms, or AV-over-structured-wiring deployments, this module lets you terminate runs cleanly at the wall rather than leaving cable loops exposed. The ivory (cream-white) finish blends with standard commercial interior hardware. HDMI 2.0 support means the connection passes 4K/60Hz signals without the bandwidth bottlenecks of earlier coupler generations.
The CMHDMIIW is part of the Panduit Mini-Com™ system, which covers a wide range of modular jacks, fiber adapters, and AV connectors on a common faceplate platform. It is compatible with any Mini-Com faceplate or housing that accepts a standard 1-port or multi-port module. For structured AV cabling deployments, pair this module with appropriately rated HDMI cable (18 Gbps rated for HDMI 2.0 runs) — the coupler itself won't degrade signal if the cable plant is within spec, but an undersized HDMI cable behind the wall will limit performance regardless of the module quality. The ivory color is designated Panduit color code cream-white; verify faceplate color match if aesthetic consistency matters in your installation.
Q: Is the CMHDMIIW compatible with HDMI 1.4 devices?
A: Yes. HDMI 2.0 is backward compatible with HDMI 1.4 devices. The coupler will pass HDMI 1.4 signals without issue; you simply won't use the full 18 Gbps bandwidth available.
Q: What faceplates does the CMHDMIIW fit?
A: The CMHDMIIW is designed for Panduit Mini-Com™ series faceplates and surface-mount boxes. It uses the standard Mini-Com single-port module footprint (approximately 18.3mm × 31.5mm).
Q: Does the CMHDMIIW support 4K signals?
A: The module supports HDMI 2.0 with up to 18 Gbps bandwidth, which is sufficient for 4K at 60Hz. Signal quality at 4K also depends on the cable behind the wall — use 18 Gbps-rated HDMI cable for the in-wall run.
Q: Is the CMHDMIIW RoHS compliant?
A: Yes. The CMHDMIIW meets RoHS and CE compliance standards per the manufacturer's specifications.
Q: What is the color of the CMHDMIIW?
A: The module is ivory (cream-white) — Panduit's standard light neutral finish for commercial interior applications.

The CMHDMIIW is the kind of component that makes or breaks a clean AV rough-in. At 18.3mm × 31.5mm, it drops into any Mini-Com faceplate cutout without displacing adjacent data ports — and because it's a true HDMI 2.0 coupler, you're not artificially capping a 4K/60Hz signal path at the wall plate the way a 1.4-era module would.
Technical Highlights:
Deployment Considerations:
Best fit for conference rooms, training facilities, and classrooms where structured HDMI runs terminate at the wall and AV sources change frequently — the Mini-Com format keeps the faceplate clean and the connection repeatable without permanent cable runs to the display.
