Front panel unshielded SCHROFF 3U (3HE) 84TE el./cr.

Unshielded front panel by SCHROFF designed for 3U (3HE) rack-mount systems with 84TE width. This front panel serves as a replacement or custom front for electronic enclosures and subracks, providing a flat, unshielded surface with multiple mounting points and cutout possibilities for modules, connectors, and controls. The panel is intended for environments where electromagnetic shielding is not required and where flexibility in panel layout and easy installation are priorities.

Advantages

The SCHROFF 3U unshielded front panel offers a precise fit for 84TE rack widths and consistent mechanical dimensions that simplify integration into existing subrack frames. Its unshielded construction reduces weight and cost compared with shielded panels while allowing easy modification for custom cutouts and component mounting. The panel is corrosion-resistant treated and finished to maintain alignment and appearance during repeated installations and maintenance.

Suitable for

• Replacement front panels in industrial subracks
• Custom control and interface panels for telecom equipment
• Prototyping and small-series electronic enclosures
• Applications where EMI shielding is handled elsewhere or is unnecessary

Key specifications

• Form factor: 3U (3HE) height compatible with standard rack-mount systems
• Width: 84TE (modular rack unit width)
• Construction: unshielded metal panel suitable for machining and cutouts
• Surface finish: protective coating to resist corrosion and wear
• Mounting: standard subrack mounting points and screw holes for module fixation
• Compatibility: designed for use with SCHROFF subracks and widely used 84TE frames

How to use

Measure and verify the subrack frame and neighboring panels before installation to ensure 84TE width compatibility. Position the panel in the front frame and secure it using the standard mounting screws provided by the rack or subrack system. If custom cutouts are required for connectors, controls, or module windows, mark and machine the panel before final installation, using appropriate metalworking tools and deburring procedures. Ensure all fasteners are tightened to recommended torque values and that any mounted components are secured to prevent movement during operation.

Usage recommendations

Use this unshielded SCHROFF front panel in systems where electromagnetic shielding is provided by other components or is not necessary. For applications requiring EMI protection, select a shielded variant or add conductive gaskets and grounding measures. When creating custom cutouts, protect edges and maintain proper clearances to ensure reliable connector mating and to avoid mechanical interference.
