Why Specify Fiber Glass Enclosures For Outdoor Control Panels?

admin

Outdoor control panels fail for a short list of reasons: water gets in, the box corrodes, or the door swing fights the wall. That is why specifiers move from painted steel to a fiberglass enclosure when the site is exposed.

The Stone Series is Famatel’s answer for that job. A hinged, gasket-sealed cabinet in fiberglass-reinforced polyester, rated IP66, with a door that can be reversed after the wall position is known.

The current site challenge

Most outdoor cabinets are asked to do more than keep rain off a breaker. The same box has to survive dust, UV, washdown, and chemicals, and still open cleanly for service.

  • Painted steel that rusts at the hinge, the gland, and every field cut
  • A fixed hinge that ends up on the wrong side of the wall
  • A seal that looks closed and still lets water track inside
  • DIN rail gear, breakers, and a PLC that cannot sit in a damp box
  • Solar, marine, and infrastructure sites where a repaint is not a maintenance plan

A basic weather cover was enough when the panel was indoors. It is not enough when the enclosure is the exterior of the system.

What you need to know about the Stone Series

Stone is a hinged enclosure line, not a junction box with a lid. The body is fiberglass-reinforced polyester. The door is gasket-sealed and reversible. Protection is IP66, so the box is built for dust and strong water jets, not a light splash.

  • Corrosion resistance where painted steel fails outdoors
  • UV-stable material for exposed installations
  • Interior laid out for DIN rail components, breakers, and PLC equipment
  • Accessories for mounting and locking without changing the cabinet format

One size in the line, SKU 49123, is 11.8 × 9.8 × 5.9 in, with a 125° door, IK10 impact resistance, and a service range from −40°C to +80°C.

Benefits on the job

  • Seal. IP66 against dust and strong water jets, with a gasketed hinged door.
  • Life outdoors. Polyester body that does not depend on paint to stay intact.
  • Install. Reversible door, so the hinge follows the site.
  • Interior. Room for DIN rail gear without a second cabinet.
  • Supply. Available through distribution, including DigiKey.

Frequently asked questions

What protection does the Stone Series provide?

IP66. That is dust-tight protection and resistance to strong water jets. It is specified for outdoor control panels, not for a light indoor splash.

Conclusion

If the panel lives outside, the enclosure is part of the specification, not a cover added at the end. Stone Series gives that panel a fiberglass body, an IP66 seal, and a door that can be turned to suit the wall.

Famatel builds the hinged line for exactly these sites. If you are choosing between steel and fiberglass for the next outdoor panel, start with the hinged enclosures or talk with the team.
