Description

The CD125-C010-1000 connector assembly is a high-performance black plastic connector made of Mitsubishi 5010G30X4 material. Designed specifically for harsh environments, this product boasts high-grade sealing performance of IP6K7/IP6K9K, ensuring stable operation within a wide temperature range from -40℃ to 125℃. It exhibits excellent electrical performance, supporting a load of 2A/100V, with low contact resistance and strong insulation. The surface of the product is treated with fine sandblasting, giving it an elegant appearance that meets automotive-grade environmental standards. It is suitable for automotive or industrial connection scenarios that demand high levels of sealing, weather resistance, and electrical stability.

Features

  • Using PBT+30% glass fiber raw materials, it features strong rigidity, dimensional stability, high temperature resistance and deformation resistance, as well as excellent insulation performance
  • Square integrated shell, with grille-type mounting ears at four corners
  • Key dimensions XB are strictly controlled, with a total length of 53mm and a total height of 61±0.1mm. The dimensions of the internal and external cavities are standardized in sections, and the tolerance system is well-established
  • A reserved imprint area is provided at the bottom of the shell, allowing for the marking of material identification and production date stamps, enabling traceability of individual product production
  • The surface shall be free of sink marks, cracks, and silver streaks; regular floating fiber patterns are allowed

Ultrasonic/Millimeter-Wave Radar Housing | Automotive ADAS System Supporting Project

The original radar housing of the ADAS perception module in domestic new energy vehicle companies faced issues such as insufficient injection molding precision, sealing failure, and deformation under high and low temperatures, leading to abnormal radar detection after water infiltration on bumpy roads. Our company has customized a modified material precision radar housing, optimized the sealing grooves and internal positioning structure, and met the automotive-grade AEC-Q reliability requirements. The housing meets the standards for shock resistance, weather resistance, and electromagnetic shielding performance. It is verified simultaneously with EPS supporting components, achieving fixed-point mass production for multiple vehicle models and significantly reducing the rework rate of radar modules.

Automotive electronic components | New energy vehicle radar housing & EPS steering system supporting projects

Domestic new energy vehicle companies have encountered issues with the original design of their onboard millimeter wave/ultrasonic radar housings, which lack sufficient shock resistance and waterproof performance. Additionally, the EPS steering connectors are prone to loosening under high-temperature conditions, affecting driving perception and steering safety. Our company has developed a dedicated precision housing for radar, which complements the EPS steering system connection components and has passed a full set of automotive-grade tests. The product is resistant to shock, high and low temperatures, and has improved assembly efficiency by 30%. It has successfully entered the mass production projects of vehicle companies and achieved stable batch supply.
