Silver anodized aluminium extruded box section to take 55mm widecircuit boards, any length upto 1.5Mtr. Ideal for small circuits, R.F. amplifiers etc. The maximum height of components on a board mounted in the bottom slot is 18mm/20mm depending on orientation. This box features dovetail slots down the side which accept a Mounting Bracket mounting bracket to facilitate surface mounting. Optional gaskets allow waterproofing. One side of the box features two sets of appearance enhancing grooves. Between the sets of grooves is a shallow (0.5mm deep) recess which could be used for a label.

• Length Tolerance: Nominal length -0mm/+1mm.
• Material: Aluminium 6063 T6 (HE9).
• Finish: Silver anodized 5 μm thickness to BS 1615 - can be painted directly if required. The inside and cut ends are not anodized.
• Perimeter: 220mm outside, 217mm inside.
• Screw ports: Nominal diameter 2.7mm to take a No.4 self tapping screw with a 3mm major diameter of a type normally used for plastic. They are not suitable for ordinary self- tapping screws that have a 2.9 mm diameter with a wide tolerance. The screw ports can be threaded M3 using a thread-rolling tap, but a thread cutting tap will make a weak thread. Alternatively an M3 thread-forming screw can be used to roll its own thread.
• End plate: End plates suit the profile of the AluCase range of extruded enclosures. The end plate is available in various finishes, including but not limited to black anodized, silver (clear) anodized and various plastics for engraving or printing. Plus the bespoke fully printed overlay on FR4
  
  Natural end plates are anodizing grade and have a removable plastic coating on one side to prevent unwanted scratches prior to application. Initially, natural end plates will look the same as silver anodized, but over time will become dull or corrode if used in an application without surface protection. They would be an ideal starting point
  if a paint or alochrom finish were required. Silver anodized end plates are intended as partners for (silver) electronic enclosures and black anodized end plates are intended as partners for (black) electronic enclosures.
• Application Information: The plain end plates are made using a ‘pierce and blank’ tool and therefore have a front with rounded edges and a back with square edges.
• Full Colour End Panels : Made using FR4 material CNC milled with client specified apertures, to match fully printed laminated graphics overlay.
• The screw holes in the end plate are symmetrical about a vertical centre line but lie closer (at 3.5mm) to the top than the bottom. This conforms to the geometry of the AluCase enclosure. They are designed to lie flush with the enclosure top and bottom and overlap the dovetails on the sides. Any Mounting Bracket inserted in a dovetail will be retained by the end plates.

End plate technical info

Material of end plate: Aluminium J57S or 5251 H22. or FR4 or laminated plastic for engraved finishes
Graphic Overlay: End plates can be supplied with digitally printed graphic overlays with laminated finish. Cut to match apertures in the end plates

 

Envelope Drawing

The envelope drawing shows the relationship between three things:
1. The circuit board in the bottom slot of the enclosure.
2. The envelope within which components must be placed.
3. The outside of the end plate.
