System / Form Factor
   Technology:       
   Your choices are...         
   CompactPCI® Compliant       CompactPCI® is a very high performance industrial bus based on the electrical specifications of the PCI bus. It is built on rugged 3U or 6U Eurocard packaging. CompactPCI is a registered trademark of PCI Industrial Computer Manufacturers' Group 
   PXITM Compliant       An extension of CompactPCI for measurement and automation. PXI was developed by National Instruments as an open industry standard. 
   Other       Other unlisted technology type. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Form Factor:      Card format is given in terms of (height x length). The height is expressed in units of 'U'.  The 'U' is a unit used for the front panel of cards.  Each 'U' is equal to 1.75 inches.  The length normally is in mm (millimeters). The most popular heights are:
  • 3U = 100 mm
  • 6U = 233 mm
The CompactPCI specifications recognizes two types of cards: A single height board, also known simply as a 3U card, is 100 mm x 160 mm with one 96 pin DIN connector (the J1connector) on the rear that plugs into the backplane.  A double height board, also known as a 6U card, is 233 mm x 160 mm and has a second 96 pin DIN connector (the J2 connector). Note: Normally the height of the card is measured in units of 'U'.  The length of the card is measured in terms of millimeters (mm).
   Your choices are...         
   3U       3U cards, also known as single height boards, are 100 mm x 160 mm with one 96 pin DIN connector (J1 connector) on the rear that plugs into the backplane. The bus width of a cPCI or PXI card with a 3U form factor is 32 bits. 
   6U       6U cards, also known as double height boards, are 233 mm x 160 mm with a second 96 pin DIN connector (J2 connector). The bus width of a cPCI or PXI card with a 6U form factor is 64 bits.

General Switch Specifications Switches are used in industrial systems to connect test points or devices to instruments for the purpose of testing, measuring or monitoring the system.
   Switch Topology:      There are three main types of functional topologies for switches:
  • General-purpose switches
  • Multiplexers
  • Matrices
   Your choices are...         
   General Purpose       Simple switches that consist of independent and isolated relays or FET switches. They can connect one input to one output. 
   Multiplexers       A multiplexer connects one input to several outputs, or several inputs to one output. 
   Matrix       A matrix switch is an arrangement with several inputs and several outputs. Any number of inputs can be connected to any number of outputs. 
   Multiplexer / Matrix       Switch arrangement that can be connected as a multiplexer or as a matrix. 
   Other       Other unlisted switch topologies. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Switch Type:       
   Your choices are...         
   Relay Switch       This switch uses a mechanical relay to rout or switch signals. It is used, among others, to switch or to scan high voltage signals.  There are three types: armature, dry-reed, and mercury-wetted switches. The relay type can be: SPST (single-pole, single-throw), SPDT (single-pole, double-throw), or DPDT (double-pole, double-throw). 
   Solid State Switch       Solid-state switches use transistors (FETs and others) to route or switch signals. They are used in applications that require high-speed scanning of low-level signals (±10 V). Because they do not have any moving parts, these switches have a very long life. 
   RF Switch       RF switches are ideal for routing high-frequency signals. 
   Other       Other unlisted switches (e.g., optical switches). 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Relay Type:      The type of the mechanical relays of the switch.
   Your choices are...         
   SPST       Single-pole, single-throw contact.  There are two types of SPST contacts:
  1. Form A:  normally open SPST switch.
  2. Form C:  normally closed SPST switch
 
   SPDT       Single-pole, double-throw relay.  It is also known as Form C type of contact. 
   DPDT       Double-pole, double-throw. 
   FETs       The switch is a solid state and the relay is a field-effect transistor (FET). 
   Other       Other unlisted relay types. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Number of Channels (Multiplexers and General Purpose Switches):       Total number of switches in the board. This is the total number of paths that the switch provides, namely
  • For (1 x n) or (n x 1) multiplexers the number of channels is n.
  • For (n x m) matrices the number of channels is the product nm.
  • For general-purpose switches the number of channels is the total number of independent switches available in the board.
