Backplane Connectors - DIN 41612

1. Overview

DIN 41612 connectors are standardized electrical connectors defined by the German Institute for Standardization (DIN). They are widely used in industrial electronics, telecommunications, and computer systems for establishing reliable connections between printed circuit boards (PCBs) and backplanes. These connectors enable modular system design, allowing easy maintenance and scalability in complex electronic systems.

2. Main Types & Functional Classification

Type	Function	Application Examples
Type A	Rectangular contacts, 3.2mm pitch	General-purpose industrial equipment
Type B	Double-ended contacts for PCB stacking	Telecom switching systems
Type C	High-density 2.54mm pitch contacts	Data center servers
Type F	Shielded contacts for high-speed signals	Industrial automation controllers

3. Structure & Composition

DIN 41612 connectors feature: - Contact System: Phosphor bronze or beryllium copper contacts with gold plating - Insulation Body: Thermoplastic materials (e.g., PA66) with high temperature resistance - Fixing Mechanism: Metal latches and polarization keys to prevent misalignment - Shielding: Optional EMI shielding for high-frequency applications

4. Key Technical Specifications

Parameter	Value Range	Importance
Current Rating	1-5A per contact	Determines power transmission capacity
Contact Resistance	10m	Affects signal integrity
Operating Voltage	50-250V AC	Safety and insulation requirement
Temperature Range	-40 C to +125 C	Environmental reliability
Insertion Force	2-10N per contact	Assembly and maintenance consideration

5. Application Fields

Telecommunications: Switching systems, routers
Industrial Automation: PLC controllers, CNC machines
Computer Systems: Server racks, mainframe computers
Medical Equipment: Diagnostic imaging systems
Transportation: Railway signaling systems

6. Leading Manufacturers & Products

Manufacturer	Representative Product	Key Feature
