Everett Charles Technologies Introduces Threaded Probe Technology

Threaded Probe

Threaded Probe

 Everett Charles Technologies (ECT) recently launched a variety of new probe designs that offer threaded retention of the probe in the associated receptacle.
Conventional probes typically use “detents” to retain the probe in the receptacle. By nature, detents offer a strong insertion and extraction force that works ideally in most applications. However, in certain situations, if a probe plunger is released instantaneously, the velocity and mass of the plunger can actually overcome the retention force of the detents in the receptacle and cause the probe to “walk-out” of the receptacle upon repeated actuations. The strong threaded attachment method of threaded probes prevents the probe from “walking out” of the receptacle.  

Threaded probes come in a variety of designs, including standard continuity, high current and switch probes with a suite of tip styles for various interconnect needs. The associated receptacles can be press-fit, glued with epoxy, or soldered into test fixtures or connector housings.

Threaded probes are featured in ECT’s latest Automotive and Industrial Catalog. Visit to download an eCatalog version. To learn more, contact Brian Crisp at

ECT provides a broad spectrum of products for automotive and industrial applications, ranging from rugged high power solutions rated more than 50 amps to fine-pitch “step” probes for non-invasive connector test applications.
