Flat rail SCHROFF 20822048, 84HP width, DIN 41612 compatible, kit of 4 pieces

Flat rail SCHROFF 20822048 is an 84HP-width mounting rail designed for use with equipment that follows DIN 41612 mechanical interfaces. Supplied as a kit of four identical flat rails, it provides a standardized support structure for printed circuit boards, plug-in modules and rack-mounted components inside industrial, telecommunications and embedded system enclosures. The rail’s 84HP width corresponds to common panel and rack layouts, enabling placement and alignment of DIN 41612-compatible connectors and subracks.

Advantages

The flat rail offers consistent mechanical support and alignment across multiple installation points, helping to maintain connector engagement and board planarity. Delivered in a set of four, it simplifies full-frame assembly or replacement of worn rails. Its dimensions and mounting pattern are aligned with DIN 41612-compatible equipment, reducing the need for custom fabrication and ensuring interchangeability between enclosures and modules.

Suitable for

• Mounting printed circuit boards and plug-in modules in industrial enclosures
• Telecommunications subrack assemblies using DIN 41612 connector systems
• System repairs, upgrades and retrofits where standardized rail width is required
• Laboratory test racks and prototype fixtures requiring repeatable board positioning

Key specifications

• Nominal width: 84HP (horizontal pitch units) suitable for standard rack/panel layouts
• Compatibility: Designed for mechanical interface with DIN 41612-style equipment
• Material: robust metal suitable for structural support (material finish may vary by production batch)
• Supply format: kit of 4 identical flat rails for multi-point installation
• Mounting: features standard hole pattern and edge profile for rack/subrack integration

How to use

Position the flat rail along the intended mounting plane in the enclosure or subrack so that the 84HP width aligns with adjacent rails or mounting references. Secure the rail with appropriate fasteners into the enclosure’s frame or pre-drilled mounting points, ensuring the rail is level and parallel to neighbouring rails to maintain connector alignment. Install printed circuit boards or plug-in modules by sliding them into the rail guidance and engaging DIN 41612 connectors as required. When assembling a complete frame, use the supplied set of four rails to ensure symmetrical support and spacing.

Usage recommendations

Use corrosion-appropriate fasteners and apply torque consistent with enclosure specifications to avoid deformation. Verify mechanical clearances for connector backshells and cabling before final assembly. For reliable operation, inspect rails periodically for loosening or wear in high-vibration environments and replace as a set if necessary.
