SCHROFF Steckbaugruppe 20818020 3HE 6TE with EL/C trapezoidal handle

SCHROFF Steckbaugruppe 3HE 6TE with EL/C trapezoidal handle is a compact front-panel plug-in assembly intended for installation in standard 19" enclosures and subracks. The unit provides a 3U (3HE) height and 6TE panel width, integrating a trapezoidal EL/C handle to enable controlled insertion and extraction of modules. It is designed for environments where secure retention, precise panel alignment and efficient use of front-panel space are required, such as industrial control cabinets and telecommunications racks.

Advantages

The plug-in assembly combines a standardized 3HE form factor with a narrow 6TE width, allowing high-density packing of modules while keeping each front panel accessible. The EL/C trapezoidal handle offers a reliable grip and positive engagement for insertion and removal operations, reducing the risk of uneven mounting or accidental disconnection. Construction materials and dimensional conformity to 19" subrack standards ensure straightforward integration and consistent mechanical performance across multiple modules.

Suitable for

• Industrial control and automation cabinets
• Telecommunications and network equipment racks
• Embedded systems and test equipment front panels
• Applications requiring modular, hot-swappable front access

Key specifications

• Front-panel height: 3HE (3U)
• Panel width: 6TE (modular width unit)
• Handle type: EL/C trapezoidal ergonomic handle for plug-in modules
• Mounting compatibility: standard 19" enclosures and subracks
• Mechanical function: panel insertion/extraction with positive handle engagement

How to use

Mount the Steckbaugruppe into a compatible 19" subrack slot aligned to the 3HE height and 6TE width. Secure the assembly according to the subrack manufacturer's mounting points or guide rails, ensuring the handle is oriented for correct insertion direction. Use the EL/C trapezoidal handle to grasp the module firmly and slide the unit into the guide rails until the front panel seats flush with the rack. To remove, operate the handle to release engagement and pull straight out along the guide rails to avoid tilting or binding. Follow any chassis or system grounding and ESD precautions during installation and removal.

Usage recommendations

For reliable long-term operation, verify compatibility with the target subrack's rail spacing and panel cutouts, avoid excessive lateral force on the handle, and perform periodic inspections of mounting points and handle engagement to maintain safe, repeatable insertion and extraction cycles.
