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

SCHROFF SUBR PRO F 3U 84HP 235D SL is a rack accessory engineered for installation of 3U modules with a front width of 84HP and a usable depth of 235 mm. It provides a standardized mechanical frame for mounting electronic modules and subracks in equipment cabinets used in industrial, telecom and data centre environments. The accessory is intended to deliver reliable, repeatable mounting geometry and to simplify integration of cards, power supplies and active components into 19-inch rack systems.

Advantages

The design offers compact, standardized mounting dimensions compatible with common Eurocard and subrack modules, helping to maintain consistent alignment and mechanical stability. The 3U height and 84HP width deliver a predictable footprint for planning rack space. A 235 mm depth allows accommodation of shallow to medium depth modules while keeping cable runs manageable. Manufactured to industry mechanical norms, the accessory facilitates quick installation and replacement of modules with minimal modification to existing rack infrastructure.

Suitable for

• Mounting 3U electronic modules and subracks in 19-inch equipment cabinets
• Industrial control cabinets and automation enclosures
• Telecommunications and network equipment racks
• Prototyping and lab benches that require standardized mounting

Key specifications

• Mounting height: 3U (standard rack unit height)
• Front width: 84HP (horizontal pitch, compatible with Eurocard widths)
• Depth: 235 mm usable mounting depth
• Form factor: subrack / rack accessory designed for module installation
• Compatibility: intended for 19-inch rack systems and compatible enclosures

How to use

Install the SCHROFF SUBR PRO F into a compatible 19-inch rack or chassis by aligning the mounting points with the rack’s front rails and securing it with appropriate fasteners. Slide or secure 3U modules into the frame according to the module guide rails and ensure proper front-panel alignment within the 84HP width. Verify that connected cables have sufficient clearance within the 235 mm depth and fasten modules or front panels to prevent movement during operation. Follow your rack and module manufacturer instructions for torque values and grounding procedures.

Usage recommendations

For reliable operation, use the accessory in racks that meet standard 19-inch dimensions and verify module depth before installation. Maintain clear airflow paths and allow service access to the front and rear of installed modules. When integrating active equipment, observe grounding and EMC guidelines to preserve signal integrity and safety.
