STAUBLI 66.2029
The STAUBLI 66.2029 is a metal plug part for 4 mm test connections. It is included as a component in Stäubli’s SLQ-4A series and is used when assembling custom test leads for professional measuring equipment. In practice, it is the part that provides the electrical connection at the end of the cable.
Stäubli describes the SLQ-4A type as stackable and with spring-loaded MULTILAM, which helps provide a secure contact in test setups where plugs are often inserted and removed. It also has a fixed insulating sleeve and solder connection, so it can be part of a self-built lead where you terminate the cable and plug yourself.
Therefore, it is relevant in test and measurement work where a 4 mm component with a standardized design and compatibility with Stäubli’s test accessories is needed. It is not a finished lead itself, but a spare part or building block for lead assembly.
