Aluform Aluminium Diecast Enclosures Overview

Aluform enclosures are robust aluminium diecast housings designed primarily for machine control rooms (MCR) and automation engineering. They accommodate front membrane and keypad interfaces and feature a distinctive rectangular dome pattern on both cover and base.

Included Components

• Enclosure set includes aluminium diecast lid, polyurethane seal (standard), captive stainless steel screws, and base with four earthing screws.

Technical Specifications

• Material: Aluminium alloy DIN EN 1706 EN AC-AlSi 12 (Fe).
• Surface Finish: Powder coated, standard colour RAL 7038 (agate grey); custom colours available on request.
• Ingress Protection: IP66 per EN 60529; higher IP ratings available upon request.
• Impact Resistance: 7 Joule as per EN 60079-0.
• Operating Temperature Range: Depends on seal type:
  • Polyurethane (PU) seal: -40°C to +90°C (standard)
  • Chloroprene (CR) seal: -40°C to +100°C
  • Silicone (VMQ) seal (optional): -60°C to +130°C

Programme Range and Dimensions

The Aluform series offers multiple enclosure sizes ranging from 80x80x81 mm up to 200x280x72 mm. Each size corresponds with specific mounting plates, DIN rails (TS 15 and TS 35), and accessories, all identified by unique order numbers.

Accessories and Options

• Mounting plates made of laminated paper.
• Stainless steel DIN rails TS 15 and TS 35.
• External mounting brackets and aluminium hinges (cast aluminium).
• EMC screening versions (SWB, SBG, SBGL) for electromagnetic compatibility.
• Allen lid screws, optional silicone lid seals for high temperature tolerance, and sealable steel lid screws for enhanced security.
• Corrosion protection options for harsh environments.

Terminal Mounting and Electrical Specifications

Enclosures support terminal mounting compatible with Weidmüller and Phoenix DIN rails (TS 15 and TS 35). Terminal specifications include voltage and current ratings, nominal cross sections, terminal widths, and types. Earth terminals are insulated, color-coded green/yellow, and available in various cross sections.

Accessories Details

• External Mounting Brackets: Sets of two, allow mounting without opening the lid; made of sheet steel with powder coating RAL 7030 (stone grey).
• Panel Holders: Enable multifunctional control terminal configurations for wall or table mounting.
• External Hinges: Sets of two, available in different widths to fit enclosure sizes; feature a conical taper downwards.
• Lid Safety Strips: Sets of two; require base modification for fastening.

Installation and Mounting Details

Detailed tables specify maximum fitting lengths, mounting plate thicknesses, DIN rail lengths, and maximum cable gland quantities per DIN 50262 standard for each enclosure type. Dimensions include corner and side measurements for cable gland placement. Assembly uses M4x20/7 cylinder screws similar to DIN 84, with dimensional tolerances per GTA 13/5 DIN 1688 for self-tapping screws.

Critical Parameters and Recommendations

• Select seal type based on operating temperature requirements to ensure proper environmental protection.
• Choose corrosion protection and EMC screening options according to environmental conditions.
• Specify installation side (A-D) when ordering external hinges to ensure correct fit.
• Adhere to DIN 50262 standards for cable gland installation and maximum allowable numbers to maintain enclosure integrity.
• Use sealable steel lid screws for enhanced security and environmental protection.

Summary

The Aluform aluminium diecast enclosure system provides a durable and versatile solution for industrial control and automation applications. Its modular design supports a broad range of sizes, accessories, and mounting options, ensuring adaptability to diverse installation needs. The enclosures offer high ingress protection (IP66), impact resistance, and temperature tolerance, with optional enhancements such as advanced sealing, EMC screening, and corrosion resistance to suit demanding environments.

Additional Mechanical and Assembly Details

• DIN Rail Lengths: Specified in millimeters (130 mm to 250 mm) matching enclosure sizes.
• Mounting Plate Thickness: Provided per enclosure size to ensure proper fit.
• External Mounting Brackets and Hinges: Designed for ease of installation; hinges have a conical taper for secure mounting.
• EMC Versions: SWB, SBG, and SBGL variants provide electromagnetic compatibility options.
• Corrosion Protection: Available for outdoor or harsh environment applications.
• Fastening: Use of self-tapping M4 cylinder screws (M4x20/7) per DIN 84 standard; dimensional tolerances per GTA 13/5 DIN 1688.

Cable Gland Capacity

Tables specify maximum numbers of cable glands per enclosure side and corner, compliant with DIN 50262. Cable gland sizes range from PG12 to PG63. Examples of enclosure types with dimensions and weights include:

• Type 04.16 16 08: 160 x 160 x 81 mm, 1120 g
• Type 04.16 24 08: 160 x 240 x 81 mm, 1900 g
• Type 04.20 20 07: 200 x 200 x 72 mm, 1440 g
• Type 04.20 28 07: 200 x 280 x 72 mm, 1920 g

Best Practices

• Match DIN rail length and mounting plate thickness precisely to enclosure size.
• Use Allen screws and silicone seals to maintain enclosure integrity and corrosion resistance.
• Respect maximum cable gland numbers to avoid overloading and maintain compliance.
• Follow installation side instructions for external hinges and brackets to ensure proper assembly.
• Use recommended screw types and respect dimensional tolerances for secure and durable assembly.
