Coaxial Contact Probes for Radio-Frequency Applications

Coaxial Contact Probes for Radio-Frequency Applications

FEINMETALL now offers a wide range of spring contact probes for radio frequency applications. Especially antenna connectors can be contacted with new coaxially built contact probes.


The probe family HF860 includes appropriate contact probes for the common connector types SMA, SMB, SMC and UFL. Extensive testing has proven an excellent performance of the probes; the frequency characteristics for each probe type are available on request. But the testing task for radio frequency applications doesn't only depend on contact probes. For RF testing always the complete transmission path of DUT, RF probe and connecting element including the scattering parameters needs to be considered. FEINMETALL offers appropriate pluggable contact elements and therefore guarantees a reproducible measurement path. With these new products FEINMETALL substantially extends the portfolio in the field of RF applications and thereby meets the current market requirements.

  • A position test at very limited space by using a probe

    A position sensor system is the ideal solution for exact measurement and documentation of pin lengths, hole depths etc. This system can be used like a contact probe even in small centers. An integrated potentiometer allows the exact determination of the position of the DUT.

  • High-Current Contacting of Blade-Connectors

    You are looking to use a flat blade connector in a high current application? But it is difficult to apply a front face with sufficient contact surface. For this reason many applications use clamps. This solution is not very durable and it has the risk of damaging the surface of the blade connector.

    The market's need for contacting semiconductor components is rapidly increasing. Components are constantly undergoing miniaturization, and so are the required contact probes for test engineering. Additionally, the signal frequencies of the test signals are getting higher and higher.

  • New Variants and Accessories for HF860 RF Probes

    The coaxially designed radio frequency probes of the family HF860 are already available for a large variety of common connectors like SMA, SMB, SMC, U.Fl., RF and others. Now the contact probe HF860 is also available for contacting FAKRA connectors (at the moment FAKRA male), that are frequently used in wire harness testing.

  • Feinmetall HF819 – optimized solution for contacting HSD-connectors

    FEINMETALL has recently redesigned the RF contact probe for contacting HSD-connectors. The new RF probe HF819 is equipped with a calyx spring for optimized guiding of the probe onto the connector. The capture area will be extended and damages can be avoided by optimizing the conical insertion of the circular contact and the position of the calyx spring. The probe HF819 is available in different versions with different tip styles of the inner pins.
