Probes Engineered for Stability Under Extreme Conditions
In conventional contact probes, piano wire (SWP) is often used as the spring material. While sufficient for room temperature and environments up to around 100°C, its performance degrades under higher temperatures. When exposed to temperatures exceeding 150°C, the spring force drops, making it difficult to maintain the required contact pressure for reliable measurements.
To address this, stainless steel (SUS) springs have traditionally been used, but even they struggle to maintain performance beyond 200°C. Seiken offers a next-generation solution by combining heat-resistant components, including springs that handle up to 300°C, to dramatically improve probe durability and maintain performance in harsh environments.
Key Features & Advantages
01 Reliable performance under high-temperature conditions
Our probes feature 300°C heat-resistant springs, ensuring reliable contact force and consistent performance even under extreme heat. Ideal for applications that demand long-term stability in elevated temperature environments.
02 Probe designed to minimize heat buildup
When high current passes through the probe, accumulation of heat can occur. Seiken’s heat-resistant design handles this challenge effectively, maintaining stable resistance values and minimizing measurement fluctuations—even during temperature spikes caused by current load.
03 Custom solutions for special requirements
We also offer custom probe designs to meet unique demands such as non-magnetic materials or other special conditions. Whatever your testing environment, Seiken can tailor a solution to meet your needs.
