During the mounting process, the probe requires a specific hole size for proper installation. In this case, the recommended mounting hole size is Φ 0.57 /.0225". This precise hole size ensures a secure and accurate fit, allowing the probe to establish reliable electrical contact with the PCB.

The Bare Board Test Probe, specified as CPM-40/R-40, adheres to specific specifications to guarantee precise and consistent testing results. The recommended minimum center distance between probes is 0.75 (.0295"), ensuring optimal spacing between the probes for effective testing and minimizing any interference between neighboring probes.

The probe has a full travel distance of 1.5(0.059") or 2.0(0.78"), indicating the maximum range of motion during testing. This range allows for comprehensive testing coverage and analysis of the PCB's performance, ensuring all critical areas are thoroughly evaluated.

With a current rating of 0.5A, the probe can safely handle electrical currents up to 0.5 amperes. This current rating is suitable for low-power applications, providing accurate testing without exceeding the probe's capabilities.
