In automotive and industrial applications, frequent exposure to shock, vibration or rough handling can dislodge terminals and cause signal interference, posing a serious challenge to the robustness of the equipment. However, the KR2500 wire-to-board connector series, with its unique friction-lock design, ensures that mating is securely fastened and provides excellent electrical reliability even in harsh environments.

In miniature wire-to-board applications, operators are often faced with misdirected mating, which can lead to impaired performance of the final product. However, the non-rectangular housing shape of the KR2500 series connectors has been cleverly designed to solve this problem and ensure accurate mating orientation.

With the growing demand for components in the consumer and automotive industries, lack of space on PC boards has become a major challenge for designers. With its compact design and secure friction-locking mechanism, the KR2500 Wire-to-Board Series connectors have successfully achieved a very small pitch of 2.50 mm, effectively solving the space limitation problem.

In addition, the KR2500 wire-to-board connector series offers single row connectors for 2 to 15 circuits in both vertical and right-angle configurations to meet diverse connection needs. At the same time, KONNRA also provides a wide range of connector options to cover the connector needs of almost all markets, providing a comprehensive and flexible solution for various industries.
