1. Accessories Overview

This section introduces a range of high-quality accessories designed to enhance electronic enclosures. Key items include telescopic slides with partial or full extension, quick-release and locking mechanisms, mounting kits, fans, cable management components, handles, enclosure feet, power strips, power supplies, fasteners, and casters. Load capacities for slides range from 35 to 112 kg per pair.

2. Telescopic Slides (Section 680)

Guidance is provided for selecting telescopic slides based on load capacity, mounting dimensions, drawer height, travel length, and special features like quick-release and locking. Load ratings assume lateral mounting with centered loads and 10,000 dynamic cycles; horizontal mounting reduces capacity by about 25%. Full use of fixing holes is essential for rated loads. Definitions clarify terms such as partial/full extension, overtravel, quick-release, and locking mechanisms.

3. Types of Telescopic Slides

Five main slide types are detailed with technical specifications:

• DZ0204: Partial extension (75%), locking in extended position, quick-release, 35-59 kg load, suitable for 1U components.
• DZ0305: Overtravel element, locking, quick-release, 55-70 kg load, 1U compatible.
• DZ3307: Overtravel, reduced mounting width (12.7 mm), separable, locking, 55-68 kg load.
• DZ3607: Overtravel, separable, locking, 92-112 kg load.
• DZ3832: Full extension, quick front separation, click-in closed position, 23-45 kg load, optional floor/platform mounting brackets.

4. Mounting Kits and Compatibility

Mounting kits tailored for each slide type enable integration into 19" racks and various enclosure depths (400-900 mm). Compatibility matrices assist in selecting appropriate drawer depths and slide lengths. Recommendations include using shorter slides for recessed installations and available mounting brackets for floor or platform setups.

5. Technical Specifications and Installation Notes

• Dimensions are metric; weights per slide pair.
• Maximum screw head height: 2.5 mm; typical diameter: 9.6 mm.
• Tolerances: ±0.8 mm linear, ±0.2 mm diameter unless stated.
• Standardized fixing hole sizes and spacing ensure compatibility.

6. Power Strips

Compact power strips with robust aluminum frames fit 19" racks at 1U height. Standard cables are 2.5 m with 3 x 1.5 mm wiring. Variants include Schuko, UTE, and IEC plugs rated for 230 VAC at 10-16 A. Some models feature switches, surge protection, and RFT filters. Available in light gray and black.

7. Fans and Accessories

AC and DC fans offer long service life with multiple connector options. Sizes range from 40x40 mm to 119x119 mm, airflow from 22 to 45 m³/h, noise levels 26-45 dB(A). Accessories include protective grills (plastic/metal), connection cables, and IP54-rated output filters with quick-mount closures.

8. Power Supplies

Power supplies support PS/2 AT and ATX systems, including redundant units with active/passive PFC. Typical dimensions are 86 x 150 x 140/175 mm. Outputs cover standard voltages (+3.3 V, +5 V, +12 V, -5 V, -12 V). Features include integrated fans, Pentium 4 compatibility, alarms for faults, and hot-swappable redundant units. Mounting hardware included.

9. Handles and Transport Grips

Universal and eco-line handles fit 19" and table enclosures up to 4U height. Adjustable positions (15° or 30° steps), materials include extruded aluminum and zinc die-cast. Load capacity up to 50 kg. Finishes: anodized aluminum, painted zinc in various RAL colors. Retractable handles with chromed steel rods and reinforced polyamide inserts also available.

10. Front Panel Handles

Available for 19" fronts, card trays, and drawers (2U to 12U sizes). Constructed with black plastic end caps and anodized aluminum grips. Mounted with M5 screws and decorative washers. Designed for aesthetic consistency with card trays and drawers; incompatible with chassis.

11. Cable Management

Solutions include 19" 1U and 3U cable passages with brush seals and strain relief, painted in RAL 7035 or RAL 9005. Cable guides with plastic/metal hoops and Velcro closures support horizontal routing. Edge protection frames and clamps organize vertical cables. Additional accessories: Velcro strips, magnetic bay lamps with switches, DIN TS 35 rails, potential equalization rails, door contacts, and thermostats with strain relief.

12. Enclosure Feet and Casters

Feet types: adhesive, snap-in, screw-mounted, retractable with anti-slip and elastic properties. Load capacities up to 50 kg. Casters include fixed, swivel, directional, double directional, and heavy-load types with/without locks. Diameters 50-100 mm; load capacities 40-150 kg. Fixation via boreholes or mounting plates.

13. Screws, Nuts, and Washers

Wide range of fastening hardware covering thread sizes M2.5 to M10, various lengths, and standards (DIN 7985, 965, 966, 934, 562, 6797, 125, 9021). Finishes include nickel-plated, galvanized, black galvanized. Special serrated washers prevent loosening. Decorative washers in plastic and brass chrome support pan head screws in front panels and drawers.

14. Assembly Components and Fastening Systems

Includes nickel-plated slotted screws, knurled screws, quick-release fasteners, and screw bases for front panel mounting. Sliding and cage nuts for groove sizes 5 x 1.5 mm and 7 x 2 mm are described, including a patented nut holder for near-flush mounting. Assembly kits (aprafix) for 19" mounting contain screws, cage nuts, and decorative washers in sets of 50.

15. Ordering and Packaging

Part numbers are provided for individual and bulk orders (50 or 100 pieces). Screws and mounting parts not included with products can be ordered separately using these references.

16. Critical Information and Best Practices

• Use all fixing holes to achieve rated load capacities.
• Apply a safety factor of 0.75 when calculating caster load capacities.
• Consider environmental stresses (vibration, heavy use) that may reduce load ratings.
• Select slide types based on extension length, load, mounting width, and drawer size.
• Utilize quick-release and locking features for maintenance and security.
• Refer to compatibility tables for mounting kits to ensure proper enclosure integration.
• Decorative and serrated washers improve fastening reliability and aesthetics.
• Assembly kits streamline installation of 19" front panels and accessories.
