CB56 Connector Board

Phoenix Contact 3.5mm Pitch Connectors


The CB56, sold without connectors, has six positions for 20-pin Phoenix Contact Connectors with 3.5 mm pitch. It offers 6 identical positions for 20-pin connectors. Position 1 is in parallel, sharing all 20 test points with position 2, but both are independent of positions 3, 4, 5 and 6. Positions 3 and 4 also share test points, as well as positions 5 and 6. You can test a 2-ended cable using positions 1 and 3 for example, or even test a 3-ended cable using position 1, 3 and 5. This board will also accept any though-hole connector with a 3.5mm pitch, up to 20-pins.

The price does not include connectors, and the board ships as a bare board. If the User provides the connectors, we will solder them into position and test the boards for a nominal charge (contact us for details). Set of two boards.
