Exploring the Dual World of Automotive High-Voltage and Low-Voltage Connectors

Automotive connectors are categorized as low-voltage and high-voltage connectors based on their operating voltage. Low-voltage connectors typically operate at 12V, 24V, or 48V. High-voltage connectors operate at voltages ranging from 60V to 800V, or even higher. High-voltage and low-voltage connectors differ primarily in appearance, structure, withstand voltage, protection requirements, EMC compatibility, and flame retardancy ratings.
