Alakehys EFB Elektronik 53711.1 — alumiini-/termoplastinen kotelo, 483×295×178 mm, harmaa

EFB Elektronik 53711.1 is a subrack designed to accommodate rack-mounted electronic modules and components. The enclosure combines an aluminium frame with thermoplastic panels, offering a compact footprint with external dimensions of 483 × 295 × 178 mm. The grey finish and mixed metal/plastic construction provide mechanical protection while keeping weight low, and the design includes space for mounting module guides and cable routing accessories.

Advantages

The aluminium/thermoplastic combination delivers a balance of durability and reduced weight compared with full-metal housings. Its compact 4U-compatible height and width suited to 84TE/3U layouts allow installation in confined equipment racks and telecom cabinets. The finished housing offers corrosion-resistant surfaces and stable mounting points for electronic modules, plus a separate cable overlength box option to manage excess cabling cleanly.

Suitable for

• Industrial control system enclosures and module integration
• Telecommunications equipment and small rack installations
• Laboratory test rigs and prototype electronic assemblies
• Field service units requiring a compact protective housing

Key specifications

• External dimensions: 483 mm (W) × 295 mm (D) × 178 mm (H)
• Construction materials: aluminium frame with thermoplastic panels
• Colour: grey
• Form factor: subrack compatible with 4U / 84TE / 3U layouts
• Includes space provision for a 1U cable overlength box
• Supplied as a single unit per pack

How to use

Mount the subrack in a suitable cabinet or on a rack shelf using standard fastening points. Install module guides and electronic boards into the internal mounting rails according to their mechanical drawings, and secure modules with the appropriate screws. Route power and signal cables toward the rear openings, and fit the 1U cable overlength box to contain excess cable length for organised wiring. Ensure ventilation around the enclosure and avoid obstructing airflow paths for heat-dissipating modules.

Recommendations

For reliable operation, use this aluminium/thermoplastic subrack in indoor, dry environments and maintain accessible cable entry points. Fasten modules to internal rails with recommended torque values and avoid overloading the mounting rails beyond their rated capacity. If the installation is in a corrosive or high-humidity environment, consider additional protective measures such as conformal coating for PCBs or a fully sealed cabinet.
