Four-point measurement of resistance between voltage sense connections 2 and 3. Current is supplied via force connections 1 and 4. In electrical engineering, four-terminal sensing (4T sensing), 4-wire sensing, or 4-point probes method is an electrical impedance measuring technique that uses separate pairs of current-carrying and voltage-sensing electrodes to make more accurate measurements ...
Typical passive oscilloscope probe being used to test an integrated circuit. A test probe is a physical device used to connect electronic test equipment to a device under test (DUT). Test probes range from very simple, robust devices to complex probes that are sophisticated, expensive, and fragile.

In electrical and electronic engineering, a current clamp, also known as current probe, is an electrical device with jaws which open to allow clamping around an electrical conductor. This allows measurement of the current in a conductor without the need to make physical contact with it, or to disconnect it for insertion through the probe.
A semiconductor manufacturer will typically require a new probe card for each new device wafer and for device shrinks (when the manufacturer reduces the size of the device while keeping its functionality) because the probe card is effectively a custom connector that takes the universal pattern of a given tester and translates the signals to ...
[9] [10] The company is a supplier for Pogo Pin connectors of major brands around the world such as Apple, Huawei, and Microsoft. Known products such as the Macbook Series from Apple Inc. [11] or the Surface Pro 4 from Microsoft are using magnet connectors from C.C.P. Contact Probes. [12]
Variety of loose pogo pins and pogo pins in 3-pin assembly holders and with Pick and Place caps Sectional drawing of a pogo pin, showing the plunger, barrel, and spring. A pogo pin or spring-loaded pin is a type of electrical connector mechanism with spring plungers that is used in many modern electronic applications and in the electronics testing industry. [1]
Some connectors are designed such that certain pins make contact before others when inserted, and break first on disconnection. [1] This is often used in power connectors to protect equipment, e.g. connecting safety ground first. It is also employed for digital signals, as a method to sequence connections properly in hot swapping.
