The KR2023 series wire-to-board connectors feature a single-row SMT design and support 2 to 10 circuits specifically developed for electronic devices with limited space and stringent reliability requirements. Its innovative ultra-slim structure (thickness < 4 mm) combined with an optimized 2.00 mm pitch significantly improves PCB space utilization. The “plastic housing + metal spring” TPA locking mechanism structurally eliminates the risk of terminal loosening. Under vibration conditions the metal spring provides precise mechanical locking to withstand shocks ensuring zero terminal displacement and pull-out while the plastic housing offers physical protection against external stress. With an ultra-wide operating temperature range of -40°C to +125°C the connector performs reliably in extreme cold outdoor environments and high-temperature industrial applications.This series has passed rigorous industry standards such as USCAR and BYD providing comprehensive reliability assurance for humanoid robots critical components. Featuring four patented designs focused on performance enhancement and structural optimization the KR2023 series significantly improves connector reliability stability durability and adaptability through meticulous engineering and innovative design. It fully supports modular lightweight and high-reliability designs in applications including smart medical devices consumer electronics humanoid robots and new energy vehicles.
Product Specifications
The KR2023 connector is rated at 5A current and 100V voltage meeting the power transmission requirements of most electronic devices. With an ultra-low contact resistance of ≤15 mΩ it ensures low loss and stable signal integrity. An insulation resistance of ≥100 MΩ (DC 500V) and a dielectric withstand voltage of 1000V AC/min effectively prevent signal crosstalk and electrical failures. The connector has passed a 48-hour salt spray test maintaining stable performance in high-humidity and high-salinity environments. The housing is made of UL94 V-0 rated Nylon 66 flame-retardant material combined with stainless steel or copper alloy conductors to provide both high mechanical strength and excellent electrical conductivity for long-term reliability in harsh conditions.
