STAUBLI XELW-4 66.9040-23
The STAUBLI XELW-4 is an angled 4 mm rigid chassis or PCB socket that is mounted directly onto the PCB by soldering. It is used as a fixed connection point for testing and measurement when a secure and robust 4 mm connection is desired directly on the board.
The angled design is practical in a work situation where the test lead should not unduly stress the PCB. This makes the connection gentler when frequently connecting and disconnecting measuring leads. The socket accepts spring-loaded 4 mm plugs with a fixed insulating sleeve and is touch-protected according to IEC/EN 61010-1, making it suitable for professional measuring equipment where safe handling is important.
The contact itself is made of machined brass and also has a 2 mm round pin and solder connections to the PCB. The 66.9040-23 variant has colour code 23, which Staubli designates as blue.
In this way, a compact and fixed 4 mm connection is achieved, suitable where a secure measuring or test point connection needs to be established directly on a PCB.
Typical applications
- Test and measurement connection on PCBs
- Fixed 4 mm connection in electronics production
- Touch-protected measuring points in professional test equipment
