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.
