Spring Contact Probe
A Spring Contact Probe is a contacting component consisting of a Plunger, Spring, and Barrel. It is used in test systems, test adapters, and Probe Cards to establish a reliable electrical connection to Test Points.
The spring travel of the spring contact probe compensates for mechanical tolerances and enables reproducible contacting even with high cycle counts. FEINMETALL Spring Contact Probes stand for low transition resistance, stable signal transmission, and long lifetime in demanding test applications.
FAQ
Thanks to their spring-loaded design, Spring Contact Probes are insensitive to tolerances, vibration-resistant, and enable reproducible measurement results even with frequent contact cycles.
Important selection criteria include spring force, spring travel, tip style, pitch, electrical properties, and the service life of the Contact Probe.
The tip style determines how the Spring Contact Probe touches or penetrates the contact surface. Depending on the application and surface, pointed, crown-shaped, or flat tips are used, for example, to ensure stable electrical connections.
