Product Details
| Core Engineering Features | Technical & Operational Advantages | Strategic Business Benefits |
| Hybrid 23-Circuit Architecture | Combines high-current (40A) power terminals with high-density (5A) signal contacts in a single interface. | Space & Cost Reduction: Eliminates the need for separate power and signal connectors, reducing PCB footprint and total assembly cost. |
| LV-214 & GMW3191 Compliance | Engineered to withstand extreme thermal cycling and intense automotive vibration levels. | Guaranteed System Safety: Ensures long-term signal integrity for critical vehicle modules, significantly reducing warranty and recall risks. |
| Right-Angle Through-Hole Design | Features a low-profile 4-row configuration with robust PCB retention pillars. | High Mechanical Stability: Ideal for space-constrained modules like ADAS or body controllers where vertical height is limited and vibration is constant. |
| Integrated Keying & Polarization | Physical “Key 1” coding and shrouding prevent incorrect mating and terminal damage during assembly. | Mistake-Proof Assembly: Streamlines the manufacturing process on the production line, ensuring 100% correct connections every time. |

Q1: Why is the stAK50h series better for automotive applications?
A: The stAK50h series is specifically designed to meet global automotive requirements. It offers high terminal density to reduce PCB size and weight while providing a hybrid interface that handles both high-power power delivery and low-level sensor signals, all while passing the rigorous LV-214 vibration tests.
Q2: What is the benefit of the “Key 1” (Dark Gray) configuration?
A: Mechanical keying prevents the header from being mated with the wrong wire-to-board receptacle. This is crucial in complex automotive systems where multiple stAK50h connectors may be present on the same PCB. Dark Gray is the industry-standard identifier for Key 1 in this series.
Q3: Can 2005021231 be used for 24V or 48V systems?
A: This specific header is rated for a maximum of 14V DC, which is typical for standard 12V vehicle architectures. For high-voltage EV battery systems, please contact us for alternative series that support higher voltage ratings.
