During the mounting process, the Loaded Board Test Probe requires specific hole sizes to securely install it on the PCB. The recommended mounting hole size is Φ 2.5 /.098". This precise hole size allows for a proper fit of the probe, ensuring a secure and accurate installation into the PCB. The secure fit guarantees reliable electrical contact between the probe and the loaded PCB, enabling precise and dependable testing and measurement.

The Loaded Board Test Probe is designed with the CPM-5 specification. This specification determines the probe's performance characteristics and capabilities during testing. The recommended minimum center distance between probes is 3.17 (.125"), providing sufficient spacing to prevent interference and enable effective testing across the PCB.

With a full travel distance of 6.4 (0.252"), the probe offers a significant range of motion during testing. This extensive travel distance allows for comprehensive testing coverage across the loaded PCB, ensuring thorough evaluation and analysis of the electronic components and their connections.

The probe has a current rating of 5A, indicating its capability to handle electrical currents up to 5 amperes. This high current rating makes it suitable for demanding testing applications that require robust electrical contact and accurate current measurements.

The contact resistance of the probe is specified as 50mΩ, representing the level of resistance encountered during electrical contact. The low contact resistance ensures minimal signal loss and precise transmission of electrical signals during the testing process. This contributes to the overall reliability and accuracy of the loaded PCB testing.
