Q: Why Choose RAST 2.5 & RAST 5.0?

A: Dual Pitch Flexibility: RAST 2.5 for compact, low-to-medium power; RAST 5.0 for high-current, rugged applications.

High Efficiency: HRB connectors feature IDC termination that eliminates wire stripping and crimping, cutting assembly time by 50%+ for automated lines.

Proven Reliability: 4-point contact design, glow-wire compliance, and positive locking ensure long-term performance in extreme conditions.

Global Standardization: Interchangeable with RAST-compliant connectors from leading manufacturers, reducing supply chain risks.

From compact smart home devices to heavy-duty industrial machinery, RAST 2.5 and RAST 5.0 connectors deliver unmatched versatility, reliability, and cost-efficiency for modern electronic design.

Q: What is the difference between RAST 2.5 and RAST 5.0 connectors?

A: The main difference lies in pitch size and current rating. RAST 2.5 adopts 2.5mm compact pitch for space-saving and low to medium power connection; RAST 5.0 features 5.0mm pitch, suitable for high-current and high-power applications. Both follow unified industry standard structure with foolproof mating and locking design.
