Eurocard is an IEEE standard format for printed circuit board (PCB) cards that can be plugged together into a standard chassis which, in turn, can be mounted in a 19-inch rack . The chassis consists of a series of slotted card guides on the top and bottom, into which the cards are slid so they stand on end, like books on a shelf. At the spine of each card is one or more connectors which plug into mating connectors on a backplane that closes the rear of the chassis.

34-428: A 133.35 mm, so that a double height card is 233.35 mm high and a triple 366.7 mm high. Enclosure heights are multiples of 3U, with the cards always 33.35 mm (1.313 in) shorter than the enclosure. Two common heights are 3U (a 100 mm card in a 5.25 in (133.35 mm) subrack) and 6U (a 233.35 mm card in a 10.5 in (266.70 mm) high subrack). As two 3U cards are shorter than
51-434: A 6U card (by 33.35 mm), it is possible to install two 3U cards in one slot of a 6U subrack, with a mid-height structure for proper support. Card widths are specified in horizontal pitch units "HP", with 1 HP being 0.20 in (5.08 mm). Card depths start at 100 mm (3.937 in) and increase in 60 mm (2.362 in) increments. The most common today is 160 mm (6.299 in), but standard hardware
68-471: Is also the basis of the " Eurorack " format for modular electronic music synthesizers , popularized by Doepfer and other manufacturers. DIN 41612 DIN 41612 was a DIN standard for electrical connectors that are widely used in rack based electrical systems. Standardisation of the connectors is a pre-requisite for open systems, where users expect components from different suppliers to operate together. The most widely known use of DIN 41612 connectors
85-469: Is available for depths of 100 mm (3.937 in), 160 mm (6.299 in), 220 mm (8.661 in), 280 mm (11.024 in), 340 mm (13.386 in), and 400 mm (15.748 in). The Eurocard mechanical architecture was defined originally under IEC-60297-3 . Today, the most widely recognized standards for this mechanical structure are IEEE 1101.1, IEEE 1101.10 (also known commonly as "dot ten") and IEEE 1101.11. IEEE 1101.10 covers
102-537: Is in the VMEbus and NuBus systems. The standard has withdrawn in favor of international standards IEC 60603-2 and EN 60603-2 . DIN 41612 connectors are used in Pancon , STEbus , Futurebus , VMEbus , Multibus II, NuBus , Acorn Archimedes expansion bus, VXI Bus, eurocard TRAM motherboards, and Europe Card Bus , all of which typically use male DIN 41612 connectors on Eurocards plugged into female DIN 41612 on
119-476: The backplane in a 19-inch rack chassis. To support the plug-in card/ backplane configuration, the "normal" versions of these connectors have right-angle PCB mounting pins on the male DIN 41612 connector and straight PCB mounting pins on the female DIN 41612 connector. There also exist "Reversed" connectors, in which the male DIN 41612 connector has straight mounting pins and the female DIN 41612 connector has right-angle mounting pins. The pin numbering of
136-463: The 6U-160 Eurocard is CompactPCI and CompactPCI Express . These are defined by PICMG 2.0R3 and PICMG Exp0 R1 respectively. Other computer architectures that utilize the Eurocard system are VME eXtensions for Instrumentation (VXI), PCI eXtensions for Instrumentation (PXI), and PXI Express . A computer architecture that used the 6U-220 Eurocard format was Multibus-II , which was IEEE 1296. Because
153-476: The Eurocard system provided for so many modular card sizes and because connector manufacturers have continued to create new connectors that are compatible with this system, it is a popular mechanical standard that is also used for innumerable "one-off" applications. Conduction-cooled Eurocards are used in military and aerospace applications. They are defined by the IEEE 1101.2-1992 (2001) standard. The Eurocard standard
170-534: The additional mechanical and electromagnetic interference features required for VITA 1.1-1997(R2002), which is the VME64 Extensions standard, as well as PICMG 2.0 (R3.0), which is the CompactPCI specification. The IEEE 1101.11 standard covers rear plug-in units that are also called rear transition modules or RTMs. The Eurocard is a mechanical system and does not define the specific connector to be used or
187-432: The cards are assumed to be installed in a vertical orientation, the usual meanings of height and width are transposed: A card might be 233.35 mm "high", but only 20 mm "wide". Height is measured in rack units , "U", with 1 U being 1.75 in (44.45 mm). This dimension refers to the subrack in which the card is to be mounted, rather than the card itself. A single card is 100 mm high. Taller cards add

#1732852703104204-459: The connectors is such that, if a "normal" connector is replaced with a "Reversed" connector, the row ordering and the pin numbering is unchanged: what was male pin a1 is now female receptacle a1. As a result, if two boards are designed to connect edge-to-edge with no backplane , one board would require a "normal" connector (male with right-angle pins) and the other would require a "Reversed" connector (female with right-angle pins). In this arrangement,
221-442: The female DIN 41612 connectors have press fit contacts rather than solder pin contacts, to avoid thermal shock to the backplane. The headline performance of the connectors is a 2 amp per pin current carrying capacity, and 500 volt working voltage. Both these figures may need to be de-rated according to safety requirements or environmental conditions. The DIN 41612 specification identifies 3 different classes or "levels": class 1
238-474: The other). The standard describes connectors which may have one, two or three rows of contacts, which are labelled as rows a, b and c. Two row connectors may use rows a+b or rows a+c. The connectors may have 16 or 32 columns, which means that the possible permutations allow 16, 32, 48, 64 or 96 contacts. The rows and columns are on a 0.1 inch (2.54 mm) grid pitch. Insertion and removal force are controlled, and three durability grades are available. Often
255-400: The row ordering is unchanged but the pin ordering is mirrored: male pin a1 is connected to female receptacle a32. Failure to appreciate this numbering subtlety led to multiple instances where prototype circuit boards had "mirror imaged" connections to their connectors: an expensive and embarrassing mistake (but at least one in which the circuit designer and the layout engineer could each blame
272-522: The signals that are assigned to connector contacts. The connector systems that are commonly used with Eurocard architectures include the original DIN 41612 connector that is also standardized as IEC 60603.2. This is the connector that is used for the VMEbus standard, which was IEEE 1014. The connector known as the 5-row DIN, which is used for the VME64 Extensions standard is IEC 61076-4-113. The VME64 Extension architecture defined by VITA 1.1-1997 (R2002). Another popular computer architecture that utilizes
