Once instruments or switching products have been chosen for a project integrators need to be supported by a range of products designed to make connecting to those modules easy. Finding the right products to provide this connectivity can be a major issue, taking an integrators valuable time as checks are made to make sure that the right connectors and cables are selected. This can be a significant investment in time and money, in some cases perhaps exceeding the initial purchase cost of the devices. We understand the importance of offering a complete range of connectivity solutions for the switching and simulation products that we supply. That is why we offer a comprehensive line of connectivity solutions that are supplied as optional accessories at competitive prices to small and large users.
Be Careful on Compatibility
Users are free to chose to purchase accessories on the open market or from us. However, some types of connectors (for example 200 pin LFH and 96-way micro D) have various types available which are not always mechanically compatible. Some of the connectors/accessories we use (such as DIN 160 pin) may have been modified in some way to fit the restrictions imposed by the PXI format on front panel space.
Normal and density and a half D Type connectors are usually trouble free as long as the correct type of connector is purchased.
If in doubt, contact your local Pickering sales office for advice. We always guarantee that parts we provide as accessories will be compatible.
Choosing the Right Accessory
Pickering can supply a number of different types of connection solutions:
- Connectors. Simple mating connectors that can provide a method for integrators to wire to a part that mates with the front panel connector of the selected device. These are ideal for systems where low purchase cost is required and labor is available to undertake the wiring operation. Some connectors are provided with back shells to protect the connecting wires, and can provide back shells with different exit directions. The direction of the exits can make wiring easier to manage by directing the cable bundles in the direction required for the connection to the test system, it can also influence the clearance distance required between the front panel of the switching system and any doors that might be used in a rack to protect the test system. Pickering can also provide prototyping PCB mating connectors to add you in your system development.

- Cable Assemblies. A range of cable assemblies with a mating connector on either one end or both ends. Cables can also be made available to convert between one connector style and another - for example converting between a high density connector suitable for use on the front of PXI or PCI modules or LXI switching systems and 50 way Ribbon Cable connectors. We can also provide options on the direction the cable exits from the connector housing.
- Terminal Blocks. A terminal block provides an interface between a mating connector and a set of screw operated terminals using a rising cage mechanism designed to minimize cable breakage or fraying. The use of breakout boxes simplifies the wiring operation to the cable and the breakout includes an effective cable grip to ensure connections are not stressed. Most breakout boxes are provided with a complete metal enclosure to protect the wiring and the cable termination. Breakout boxes are normally designed for use in applications below 200V, for higher voltage applications cable assembly based solutions are recommended
Breakout box includes screw terminals for users to simply connect their own cables to the module connector
Modules can be used with cable assemblies to link them to breakout boxes
- DIN Fuse Holders and Terminals. To help complete your system cabling requirements, Pickering provides a complete range of DIN fuse blocks and terminals.
