SCHROFF ratiopacPRO enclosure RATIOP.PRO FB 3U 84TE 255mm depth (24571038)

The SCHROFF ratiopacPRO enclosure RATIOP.PRO FB 3U 84TE 255mm depth is a modular 3U rack-mount housing designed for electronic and industrial applications. It provides a standardized 19-inch frame with 84 TE of front panel width and a chassis depth of 255 mm, allowing installation of Eurocard-style boards and plug-in modules. The enclosure delivers mechanical protection, organized front-panel accessibility and compatibility with rack-based installations where compact depth is required.

Advantages

This ratiopacPRO enclosure combines a compact chassis depth with a broad front panel allocation, enabling high module density in limited rack depth. The standardized 84 TE front enables easy mounting of front panels and connectors while maintaining consistent mechanical alignment. Built for industrial use, the housing supports secure installation, straightforward service access from the front, and integration into 19-inch systems without requiring additional frame modifications.

Suitable for

• Mounting Eurocard-style circuit boards and plug-in modules in 3U format
• Industrial control cabinets and rack systems with limited depth
• Test benches and measurement stations requiring modular front access
• Replacement or upgrade of existing 19-inch rack equipment with shallow chassis requirements

When it may not be suitable

The enclosure’s 255 mm chassis depth is intended for compact installations; it may not accommodate deep power supplies, large cooling components or oversized peripheral modules. Systems requiring extensive internal cabling, large heatsinks, or multiple full-size power modules could need a deeper chassis or alternative housing with greater internal volume.

Key specifications

• Form factor: 3U rack-mount housing
• Front panel width: 84 TE
• Chassis depth: 255 mm
• Mounting standard: 19-inch compatible frame
• Access: front-panel accessibility for modules and connectors

How to use

Install the enclosure into a standard 19-inch rack or cabinet using the front-mounting points. Fit Eurocard-style boards or module carriers into the available 3U slots and secure them to the front panel using the standardized TE spacing. Connect power and signal cabling as required, keeping cable routing neat to preserve airflow and service accessibility. Use appropriate blanking panels or ventilation options if some front positions remain unused to maintain predictable thermal behavior.

What to consider before purchase

• Verify that 255 mm chassis depth accommodates the height and depth of intended boards and power supplies
• Confirm that 84 TE front width matches the required number of module positions and front-panel connectors
• Check compatibility with your 19-inch rack or cabinet mounting arrangement
• Consider cooling and cable routing needs for your specific modules

Usage recommendations

For optimal results, plan module placement to balance heat-generating components and preserve service access at the front. When integrating power supplies or fans, verify available clearance within the 255 mm depth and, if necessary, select low-profile or external power options to ensure reliable operation.
