  1. Enclosures, Cables and Connectors

  2. Materials available: ABS plasic Polycarbonate Fiberglass Stainless Steel Aluminum Enclosures • Needs to withstand hostile environments-rain, snow, saltwater blowing debris. • Needs a full hinge and a positive latching system. • Nema type 4 or 4X

  3. ABS Plastic: Advantages and Disadvantages • Light • Easily modified by machine shop • Nonconductive • Brittle • Not UV resistant – needs paint • No Hinged Units

  4. Polycarbonate: Advantages and Disadvantages • Light • Easily modified by machine shop • Fairly durable • More UV resistant than ABS plastic • Nonconductive • Black or clear color • Still needs to be painted for UV resistance • No Hinged Units

  5. Fiberglass: Advantages and Disadvantages • Lightest • Easily modified by machine shop • More durable than Polycarbonate • Mostly UV resistant • Nonconductive • Best R factor • Most inexpensive • Pain to machine (dust) • Will break down over long time (years) if not painted

  6. Stainless Steel: Advantages and Disadvantages • Most durable of all materials (will last forever) • Pain to machine (hard material) • Most heavy • Conducts heat/cold/electricity • Most expensive

  7. Aluminum: Advantages and Disadvantages • Very durable (will last forever) • Easy to machine • Expensive • Heavy • Conducts heat/cold/electricity • Needs coating • 2nd most expensive

  8. Sizes and Costs • Material Size Weight Price • SS 16 x 14 x 6 20 673.80 • 16 x 12 x 8 23 788.10 • Fiberglass 16 x 14 x 8 10 152.30 • 15.5 x 12 x 8.25 11 289.60 • Al 16 x 14 x 6 8 392.90 • 16 x 12 x 6 10 670.50 • 20 x 16 x 10 16 885.60

  9. Jacket choices: PVC, teflon, polyurethane Inner insulation choices: PVC, teflon, polyethylene Cables • Hostile environments – water, snow, cold, heat, mud, saltwater, rodents, farm machinery • No. of traces? • Standard lengths?

  10. Cable Costs • 22 AWG 4 twisted pairs, PU jacket, PE insulation – 1000 ft @ $1.46/ft - 2500 ft @ $1.19/ft • 22AWG 5 conductors, tpe jacket and insulation, $2.78/ft • 22 AWG 4 twisted pairs, PVC jacket, shielded, 500 ft @ $1.22/ft

  11. Connectors • Weather resistant • Small in size • No of pins? • Multiple insertions/extractions • Easily installed on cables • Cost

  12. Connectors • AMP CPC series 1 connectors • Bulgin 900 series “Buccaneer” • Bulgin STD Buccaneer • Bulgin 400 series Buccaneer • Conxall • Amphenol mil-spec connector
