INTRODUCTION
We produce filtered Sub-D connectors in standard ranges and many custom designs. The advantage of applying filtering in the connector is that the interference is suppressed before it can enter you system to possibly radiate to other circuits. Whatever your requirement in connectors, be it standard density, high density, mixed layout Sub-D or any other type, we can probably supply you. Filter options include feedthrough capacitors, Pi-filters and ferrites. Selective filtering with a mixture of different filters in the same connector are produced. Pins can be grounded or omitted altogether for keying. We can also supply various fixing options and mounting gaskets.
SPECIFYING CUSTOM CONNECTORS
If you would like us to design a filtered (or otherwise special) connector to meet your requirements, please send us the following information. If you do not have all the information available, please just give what you can.
1. Specify the application.
2. If you have a preference for a particular hardware design (for example Sub-D), please state it. Otherwise, specify the maximum dimensions of the space you have available for the connector.
3. Specify any special physical requirements you may have for the connector. For instance, you might want IP64 rating or an explosion proof design.
4. Specify your estimated requirements of quantities and delivery dates both for short term and long term. This is important because it may influence what hardware is specified for the design.
5. If you have a target or maximum price level, please state it.
6. If you are not specifying the connector hardware, please specify the currents flowing in all circuits of the connector. Give as much detail as you can.
7. EITHER: Specify minimum required impedance at particular frequencies or sketch a graph of minimum required impedance versus frequency. Do this for all circuits of the connector.
OR: Specify what filter elements (for instance, 1nF capacitors) you require on each circuit of the connector.
8. Specify working voltages. Give as much detail as you can.
