RS PRO 1.27mm Pitch Spring Test Probe With Needle Tip, 1.5A This pitch spring test probe is an ideal solution for safely testing out contacts in an electrical circuit. It's made up of a spring, a plunger and a tubular barrel. The probe is designed to be wired into a receptacle, which can be housed. Having the probe and receptacle separate like this lets you easily replace or repair the probe if it gets damaged. The phosphor bronze material used to make the probe is strong and resilient. This is further enhanced by the gold-plating finish, which also offers excellent conductivity for reliable testing. The probe is 16.35 mm in length, allowing you to test contacts from a distance with its spring-loaded needle tip. This pitch spring test probe is commonly used to test PCBs (printed circuit boards) and components, as well as batteries and consumer electronics devices like tablets or smartwatches.
