Front panel SCHROFF SUB-D cutout TEILFRONTPL.3HE 4TE 2x9 DC, mounting panel for SUB-D connectors

SCHROFF SUB-D cutout TEILFRONTPL.3HE 4TE 2x9 DC front panel is a metal mounting panel designed to accept two 9‑pin D‑sub (SUB‑D) connectors in a compact 3U (3HE) height and 4TE width format. The panel provides a standardized, rack‑compatible front interface for enclosures and chassis, enabling secure mechanical fixation of connectors and helping maintain organized cable routing for industrial, telecommunications and electronic systems.

Advantages

The metal construction ensures mechanical stability and electromagnetic robustness while keeping the panel thin and compatible with standard rack layouts. Pre‑cut SUB‑D openings are sized for two 9‑pin connectors, reducing preparation time during assembly. The standardized 3HE height and 4TE width allow straightforward integration into existing modular front panels and subrack systems, and the mounting holes align with common connector fastening practices to ensure secure attachment.

Suitable for

• Mounting two 9‑pin D‑sub connectors on a 3U front panel
• Industrial control cabinets and electronic enclosures
• Telecommunications and networking equipment requiring D‑sub I/O
• Prototyping and repair of rack‑mounted devices

Key specifications

• Panel material: metal construction for durability and grounding
• Height: 3U (3HE) compatible
• Width: 4TE modular width
• Connector cutouts: two 9‑pin D‑sub (SUB‑D) openings
• Mounting: provision for standard SUB‑D fastening and screw mounting to panel frame
• Finish: industrial protective surface treatment suitable for enclosures

How to use

Install the front panel into the enclosure or subrack by aligning the 3HE height and 4TE width with the corresponding mounting rails, then secure the panel with screws through the provided mounting points. Fit each 9‑pin D‑sub connector into its respective cutout from the rear of the panel and fasten using the connector’s standard thumbscrews or nuts. Route and secure cable assemblies behind the panel to avoid strain on the connector terminations and to maintain clear access at the front.

Usage recommendations

For reliable electrical grounding and mechanical stability, mount the panel to a conductive chassis and use proper fastening hardware for the SUB‑D connectors. Verify clearance behind the panel for connector backshells and cable bundles; apply strain relief where cables exit the enclosure to prevent connector damage over time.
