To mount the probe onto the PCB, a specific hole size is required. In this case, the mounting hole size is Φ 1.0/.039". This precise dimension allows for secure and stable installation of the probe into the PCB, ensuring a reliable and consistent connection for effective testing.

The Probe specifications for this particular model are identified as CPM-050L / R-050L. These specifications outline the key characteristics and capabilities of the probe. The recommended minimum center distance between probes is 1.25(.050"), providing an optimal spacing to avoid interference or cross-talk between adjacent probes on the PCB. This spacing is crucial for accurate and reliable electrical measurements during testing.

The probe has a full travel distance of 6.9(0.272"), allowing it to reach the desired test points on the loaded PCB effectively. With a current rating of 3A, the probe can handle electrical currents of up to 3 amperes without compromising its performance.

The contact resistance of the probe is specified as 75mΩ, ensuring low resistance and minimal signal loss during testing. This characteristic is vital for obtaining accurate and reliable electrical measurements.

The probe is equipped with springs that provide two different forces: 200g and 300g. This versatility allows for accommodating various testing requirements, ensuring proper contact and reliable measurement outcomes.
