This is a listing of Equipment Enclosures and Chassis manufacturers. The types of products or equipment they produce are listed under the company name, with supported architectures, in alphabetic order. There are a number of terms, which all mean the same thing, used to describe an electronic enclosure which hold circuit cards: Case, Chassis, Crate, Mainframe, and Enclosure. The enclosures may also be sub-divided into Rack-Mount, Wall-mount, Tower, or table-top; Commercial, Industrial, Rugged, or Military. A Sub-rack is not a complete electronic enclosure and may only include a metal frame and a card cage. A Card Cage has no enclosure at all and is just a frame [with card guides] to support the particular CCA form factor used.
If the Chassis is produced for a particular card form factor, for example cPCI, then you can also check that particular BUS page for more data or the COTS card vendors page for a listing of CCA manufacturers.

Compact PCI Vendors

Compact PCI [cPCI] Chassis will be between 1 and 8 slots (the maximum). Compact PCI [cPCI] cards are spaced on 0.8 inch centers.
The cPCI chassis may except 3U cards, or 3U and 6U cards. The chassis may have a separate card cage to handle the 3U cards.
The cPCI chassis shall provide a +5 volt, +/- 12 volt and a 3.3 volt supply @ maximum ripple 50mV. I believe the Telcom cPCI version provides 48 volts as the system power.
The Compact PCI [cPCI] backplane is passive. The bus requires one card acting as the systems controller residing at either end of the back-plane (chassis), termed the System Slot. The remaining cards (slots) are termed the Peripheral Slots. The chassis may be a table-top or rack-mount.
In CompactPCI [cPCI], the system slot may reside in any slot of the back plane with the other 7 slots as peripheral cards. In PXI, the left most slot is the system slot followed on the right by 7 peripheral slots. In addition, 3 other slots, with do not contain back plane connectors may reside to the left of the system slot. These additional 3 slots provide expansion (wider card) for the system card.
Refer to the cPCI Design Information page for more background data.

Note: A cPCI chassis could be the exact same size as a PXI or VME chassis.






PC Cases and Enclosure Vendors

Now listed on the PC Case manufacturers page. Personal Computer Case Sizes: XT, AT, Mini-AT, ATX, Desktop, Tower, Full Tower, Slim Tower.
ATX Desktop; 430mm [wide], 170mm [High] x 460mm [deep]
MicroATX; 5.35" x 13.78" x 13.58"
BTX AV Style; 17" x 4" x 15.5" [Audio Visual Style]

VME Chassis Manufacturers

A VME Chassis will be between 1 and 21 slots (the maximum). Care should be taken producing a 21 slot chassis, with the addition of slide rails the width may exceed a standard 19" [EIA-310] rack. A backplane will start with 2 slots, one slot has no value.

The VMEbus chassis may except 3U cards, or 3U and 6U cards, and now 9U cards. The chassis may have a separate card cage to handle the 3U cards. The chassis only need provide the P1 side of the back plane when only 3U cards are used. 6U cards require both P1 and P2, and 9U would require the P1, P2, and P3. A P0 connector (between P1 and P2) for 6U cards may also be provided. Regardless of the size of the card the chassis will accept (3U, 6U, or 9U) all the slots are on .8" centers. The chassis may be a table-top or rack-mount.

VME32 provided a +5volt,and +/-12volt supply; VME64 added a 3.3volt supply. The 5 volt supply should provide only 50mV of ripple. No currently produced power supply meets 50mV, I've seen notes on the web indicating an attempt to update this number.

This listing has been moved to VME Equipment Chassis Manufacturers. Refer to VME Bus Description


VXI Crate Manufacturers

Now listed on the VXI chassis Manufacturers page. Refer here for more VXI Bus Design Information.

A VXI [(VME eXtensions for Instrumentation] Chassis will have between 1 and 13 slots

VXI Chassis Terms:
"A-size" mainframe: Provides J1 only {mandatory}, allows for the insertion of an A-size module only.
"B-size" mainframe: Provides J1 {mandatory}, J2 {optional}, allows for the insertion of a B-size module.
"C-size" mainframe: Provides J1 {mandatory}, J2 {optional}, allows for the insertion of a C-size module.
"D-size" mainframe: Provides J1 {mandatory}, J2 and J3{optional}, allows for the insertion of a D-size module.

The VXIbus chassis may except 3U cards, or 3U and 6U cards, or 9U cards. The chassis may have a separate card cage to handle the 3U cards or 6U. The chassis only need provide the P1 side of the back plane when only 3U cards are used. 6U cards require both P1 and P2, and 9U would require the P1, P2, and P3. A P0 connector (between P1 and P2) for 6U cards may also be provided. Regardless of the size of the card the chassis will accept (3U, 6U, or 9U) all the slots are on .8" centers. The chassis may be a table-top or rack-mount.
