Backplane Connectors - DIN 41612

Backplane Connectors - DIN 41612: High-Density Interconnect Solutions for Robust System Integration

Definition & Purpose
Backplane Connectors - DIN 41612 are standardized, high-density interconnect components designed for modular electronic systems requiring reliable signal and power transmission between printed circuit boards (PCBs). Compliant with the DIN 41612 standard (IEC 60603-2), these connectors feature a rectangular form factor, polarized mating interfaces, and multiple contact configurations to support applications demanding high pin counts, mechanical stability, and consistent electrical performance.

Key Types & Variations
1. By Orientation:
- Vertical (Type V): Perpendicular PCB mounting for space-efficient backplane architectures.
- Right-Angle (Type R): Parallel PCB alignment for streamlined horizontal stacking.
2. By Contact Pitch:
- Standard (2.54mm pitch): Balanced density and ease of soldering for industrial controls.
- Fine-Pitch (1.27mm): High-density layouts in telecom/datacom equipment.
3. By Contact Type:
- Solder Pin: Through-hole termination for robust mechanical bonds.
- Press-Fit: Tool-free installation for high-volume assembly.
4. Shielding Options:
- Unshielded (cost-effective for low-noise environments).
- Shielded (EMI protection in sensitive RF/military systems).

Selection Guidelines
- Current/Voltage Requirements: Match contact material (e.g., brass with gold plating for low-resistance power delivery) and pin count to load demands.
- Environmental Factors: Opt for IP-rated or ruggedized housings in harsh industrial/military settings.
- Mating Cycles: Prioritize connectors with 500 cycles for frequently swapped modules.
- Compliance: Verify IEC 60603-2 certification for interoperability.

Why DIN 41612?
These connectors remain a benchmark in legacy and modern systems from telecom switches to test instrumentation due to their proven durability, modular flexibility, and cost-efficient scalability. For OEMs, adherence to this standard simplifies backward compatibility while future-proofing designs.
