Getting the best performance out of Type 43 connectors
We are always looking for ways to improve our products and services. Some of these improvements may appear insignificant but they can make a big difference to our customers.
For example, one of our recent introductions is the addition of a Cable Stripping Template on the inside lid of our retail trays for Type 43 connectors. This template can be used to check that the cable is prepared to the correct strip lengths before termination.
The template also carries an important warning that for foiled cables the foil should not be removed. It has come to our attention that many installers are stripping the foil back too far. Installers do this because they have become used to connectors from manufacturers who have cut corners by employing the same connector design for both non-foiled cables and foiled cables. This means that the only way the dielectric will fit into the connector is by removing the foil. This is not good practice as explained later.
Interface Components Limited designs and manufactures connectors to fit the specific cables types. The main reasons we employ this good practice are:
- Electrical Performance – the frequency response of cables terminated with the foil left in place is smooth when displayed as a graph, whereas the graph for cables with the foil removed, and therefore not inserted into the back of the connectors, displays severe spikes.
- Speed of Termination – removing the foil can sometimes be difficult and at the very least introduces an unnecessary step into the process. Ironically, one of our competitors offers what is described as a quick termination Type 43. But you have to remove the foil to use it with foiled cable and therefore the termination time is increased and the performance compromised.
- Ease of Termination – the foil provides extra stiffness to the dielectric and makes it easier to insert the contact into the connector.
Please contact us if you require any help with terminating Type 43 or any other of our connectors.
