Achieving a pitch of P=0.2mm! Active in environments that require strict non-magnetic properties. Uses materials suitable for lead-free electrodes.
To non-magnetize contact probes, it is essential to review the materials and surfaces, but in practice, that alone is not sufficient for the product to be viable. It is only natural that they should be non-magnetic when measuring non-magnetic devices, but they must also possess performance tailored to the characteristics of the electrodes being inspected. Our company offers a lineup of "non-magnetic probes" that are suitable for lead-free electrodes, provide load control for contact probes, and achieve a pitch of P=0.2mm. [Features] ■ Materials suitable for lead-free electrodes ■ Load control for contact probes ■ Achieves pitch compatibility of P=0.2mm *For more details, please refer to the PDF document or feel free to contact us.
By bringing the tip of the contact probe closer to the outside, the gap between the two points can be minimized without changing the thickness of the pin. Pin pitch between 0.4mm and...
The "Kelvin Probe" has its tip positioned right at the edge of the probe's outer shape. By moving the tip outward, it is possible to minimize the gap between two points without changing the thickness of the pin. This allows for stable contact at a fixed position and the maintenance of load. Special board processing is required for use. Our company offers the fabrication of fixtures that can be installed according to the measuring equipment used by our customers. 【Features】 ■ The tip is positioned right at the edge of the probe's outer shape. ■ It can minimize the gap between two points without changing the thickness of the pin. ■ Stable contact at a fixed position. ■ It can maintain load. *For more details, please refer to the PDF document or feel free to contact us.
Compared to conventional BeCu products, it is equivalent or even superior, so wear resistance is not a concern.
At Seiken, in addition to our approach to surface treatment, we have re-evaluated the materials themselves. Traditionally, we used BeCu (beryllium copper), which required surface treatment. However, we have processed an alloy that excels in solder contact properties, allowing it to be used as is without any surface treatment. Even when cleaning the pin tips, the plating thickness is at most 1-2 micrometers, but since the alloy is used in its solid form, there is no risk of plating peeling that would expose the base material and degrade performance. Additionally, the hardness is comparable to or greater than that of traditional BeCu, so wear resistance is not a concern. This material can also be processed for probes in the P=80 micrometer class. *For more details, please refer to the PDF document or feel free to contact us.*

A specialized manufacturer of contact probes explains! How to use and replace standard probes and both-end probes.
We would like to introduce the usage of the "Contact Probe" that we handle. The "Standard Contact Probe (Single-End Probe)" is basically used in pairs with a socket due to the ease of replacement and wiring. The general method of using a contact probe involves drilling a hole in the resin, embedding a socket (receptacle) in it, and connecting the lead wires for wiring. Finally, the contact probe is inserted into the socket to complete the setup. Additionally, our website also provides information on "How to Use a Double-End Contact Probe" and "Replacing a Double-End Probe."
