Questions & Answers Ask a Question

What diameter hole should the sleeve be pressed into – undersize from the 1.83mm diameter or to size?

You have a choice how you mount this sleeve. You can either use the retaining bump (diameter 1.83mm) as a shoulder, to locate the sleeve at a precise point within the PCB/fixture, or as a retaining interference fit feature. For the interference fit, the hole diameter is given on the Technical Drawing, at 1.75mm diameter – although this may need adjusting for different panel materials.

These two options are also covered in the Instruction Sheet. Please do not make the mounting hole to the same size as the retaining bump at 1.83mm diameter, as no retention will occur.

Is there a recommended insertion tool that I can use with S25-022 and P25-0423?

We do not have a specific insertion tool for our ATE test probe sleeves. If you are press-fit assembling the S25-022 sleeve to a panel, you would just need to support the underside of the panel around the mounting hole, and push down on the sleeve with a flat plate. A typical bench press should be suitable. The probe should then be fitted to the sleeve by hand. There is also an instruction sheet available for these products.

S25-022 and P25-0423 – Which item contains the spring?

The Probe is the P25-0423 part – this is the item with the internal spring. The Sleeve is S25-022 – it’s basically a hollow tube used to mount the probe to the PCB or test bed.

Why is there no voltage rating for this contact?

Voltage rating is calculated from the flashover voltage – the voltage at which the electricity can break down the air gap and jump between two contacts. With a single contact, the voltage rating you achieve will depend on the space you leave between two contacts, or a contact and any other conducting element. So we are unable to give a voltage rating for single contacts, as it will depend on your usage.
