Overview

KR1250 series connector is a high performance and high reliability electronic connector product. It is widely used in the electronics field due to its compact design, small pitch and friction lock. The KR1250 series connectors support wire-to-wire and wire-to-board connections for a wide range of applications such as consumer electronics, industrial equipment, medical equipment and commercial vehicles. Their unique two-point contact design and polar mating geometry ensures a reliable electrical connection even under low current, low voltage and vibration conditions. In addition, the KR1250 series connector connectors are RoHS compliant, demonstrating their environmentally friendly and sustainable characteristics.

Advantages

• Compact Design

The KR1250 series connectors are designed with a 1.25mm pitch, which saves up to 45% of printed circuit board space compared to 2.00mm pitch connectors, allowing for a more compact design of electronic devices.

• High Reliability

The KR1250 series connectors feature a friction locking mechanism that engages the two locking bevels in the crimp housing with the locking window of the connector housing, creating a strong friction force that ensures a solid connection and prevents accidental disconnections due to mishandling or vibration.

The SMT headers are equipped with solder lugs that not only ensure a secure fixing on the printed circuit board, but also act as strain relief devices to further minimize the risk of breakage of solder joints due to mishandling.

• Wide applicability

The KR1250 series connectors offer both wire-to-board and wire-to-wire connection options and can be used in a variety of application scenarios, including automotive, medical, industrial process control, and more. A variety of circuit options are available, including configurations from 2 to 16 circuits, to meet the needs of different electronic devices.

• Flexibility and Versatility

The KR1250 series connectors offer both vertical and right-angle mounting, as well as DIP and SMT mounting types to accommodate different design requirements. Multiple wire sizes are supported, including 28AWG to 32AWG.

• Environmentally Friendly

The KR1250 series connectors are RoHS compliant, demonstrating a commitment to environmental friendliness and sustainability.

• Wide Operating Range

The KR1250 series connectors operate in temperatures ranging from -40°C to 105°C, demonstrating good temperature adaptability.

• High-quality materials

Phosphor bronze contacts are used to ensure the stability and reliability of current transmission; the contact area is tin-plated to improve corrosion resistance and conductivity.

In summary, the KR1250 series connector connectors have become the preferred connectivity solution for many electronic equipment manufacturers due to their compact design, high reliability, wide applicability, flexibility and versatility, environmental friendliness, wide operating range and high quality materials and other advantages and features.
