Spring Probe: Design and Functionality

Spring Probe: Performance Characteristics

Electrical Performance: Spring probes are known for their low contact resistance, typically less than 10 mΩ, which is crucial for maintaining signal integrity in both analog and digital applications. They can handle high frequencies, with capabilities of up to 20 GHz and data rates of 12 Gb/s

Current Rating: Depending on the specific design, spring probes can support various current ratings, with some capable of handling up to 30 Amps

Temperature Range: These probes can operate effectively across a wide temperature range, typically from -55°C to 250°C, with some materials allowing for even more extreme conditions

Spring Probes Common Applications

  • Harsh Environments: Spring probes are ideal for applications in industries such as aerospace, military, automotive, and industrial automation, where they can withstand extreme conditions. Their durability and reliable performance make them comparable to advanced solutions like waterproof pogo pin connectors, which are specifically designed to maintain functionality in harsh environments.
  • Modular Components: They are often used in modular designs where quick disconnects are necessary, allowing for easy maintenance and replacement of components.
  • Blind Mate Applications: The unique design of spring probes allows for blind mating, where the connector can engage without direct line of sight, making them particularly useful in compact or difficult-to-access spaces.

What is Spring Probe’s Structure?

The spring probe is the contact medium for electrical testing and is a high-end precision electronic hardware component. It mainly consists of three parts: spring, plunger, and barrel.

From the component structure part, the spring probe is associated with the spring. However, it is not a probe supported by a spring; the spring is only a structure inside it.

What is The Working Principle of The Spring Probe?

Testing whether the dut is working properly can give the manufacturer feedback on their process problems. Meanwhile, It can screen out the bad products to reduce the waste of subsequent finished products.

Read More

The working principle of the spring probe is mainly to send special electronic signals through the tested equipment, and the spring probe is fed back to the test system.If the returned test signal is accurate and the tested equipment passes the test within the desired time, it is a good product. If not, is defective. At the same time, the test system will analyze the electronic signal to determine which test the equipment does not pass.
