Rack accessory SCHROFF SUBR PRO F 3U 84HP 235D SL Shielded — 3U, 84HP, 235 mm depth, shielded

SCHROFF SUBR PRO F 3U 84HP 235D SL Shielded is a rack accessory designed for 19" enclosure systems. The unit occupies 3U of rack height and provides 84HP usable front panel width with a 235 mm installation depth. The shielded construction offers electromagnetic compatibility (EMC) protection for mounted modules and cabling, enabling compact, organized, and interference-reduced installations in server, telecom and industrial cabinets.

Advantages

The shielded frame reduces electromagnetic emissions and susceptibility by providing a continuous conductive enclosure between front and rear parts, helping to meet EMC requirements. The 3U form factor with 84HP width supports standard eurocard-style modules and front panels while the 235 mm depth is suitable for shallow to mid-depth modules and wiring. The accessory's mechanical design focuses on stable mounting, straightforward module insertion and reliable electrical contact for grounding and shielding.

Suitable for

• Mounting eurocard-format modules and front panels in 19" enclosures
• Shielded installations in server rooms and telecom racks
• Industrial control cabinets requiring EMC mitigation
• Compact systems where 235 mm depth is sufficient

Key specifications

• Rack height: 3U
• Front panel width: 84HP (horizontal pitch units)
• Maximum installation depth: 235 mm
• Construction: shielded frame for EMC protection
• Compatibility: designed for 19" enclosure systems

How to use

Install the accessory into a standard 19" rack by aligning the mounting points at the designated 3U position and fastening with appropriate rack screws. Insert modules or front panels into the 84HP aperture and secure them according to module fastening requirements. Ensure that the rear connections and cabling are routed within the 235 mm depth allowance and that grounding/shielding contact points are engaged to maintain EMC continuity.

Usage recommendations

Verify module depth and connector clearance before installation to confirm compatibility with the 235 mm depth. Maintain continuous grounding between the accessory and the rack chassis to preserve shielding effectiveness. For mixed-signal or high-speed applications, separate power and signal cabling where feasible and follow rack airflow and cooling guidelines to avoid overheating.
