Frequently Asked Questions Ask a Question

Is there a recommended insertion tool that I can use with the ATE probes and sleeves?

We do not have a specific insertion tool for our ATE test probe sleeves. If you are press-fit assembling the 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.

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.
