Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board)

Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) - Category Overview

1. Definition:
Rectangular Connectors - Arrays, Edge Type, and Mezzanine (Board to Board) are specialized interconnect solutions designed for high-density, reliable connections between printed circuit boards (PCBs) or modular electronic systems. These connectors feature rectangular housings with precise alignment mechanisms, ensuring secure mating for signal, power, and data transmission in compact or complex assemblies.

Arrays: Multi-pin configurations arranged in grid patterns for high-speed data transfer and space efficiency.
Edge Type: Connectors mounted along PCB edges, enabling direct board-to-board or board-to-cable interfacing.
Mezzanine (Board to Board): Stackable connectors that vertically link parallel PCBs with low-profile designs, ideal for layered architectures.

2. Product Types:
This category includes:
- Header and Receptacle Pairs: Gender-specific pairs for permanent PCB mounting.
- Shrouded/Unshrouded Connectors: Shrouded variants offer mechanical protection, while unshrouded types suit tight spaces.
- High-Speed Mezzanine Connectors: Optimized for differential signaling (e.g., PCIe, SATA).
- Press-Fit/Surface-Mount (SMT) Options: Flexible termination styles for automated assembly.
- Hybrid Connectors: Combine power and signal contacts in one housing.

3. Purchasing Recommendations:
- Pitch Size: Select 0.5mm 2.54mm pitch based on current load and space constraints (smaller pitches for high-density designs).
- Current Rating: Verify ampacity (e.g., 1A 5A per contact) for power applications.
- Material: High-temperature plastics (PBT, LCP) or metal housings for rugged environments.
- Mating Cycles: Choose connectors rated for 500+ cycles if frequent disconnection is expected.
- Compliance: Ensure adherence to standards like IEC, UL, or MIL-SPEC for industrial/military use.

Ideal for embedded systems, telecom hardware, and IoT devices, these connectors balance density, durability, and signal integrity. Partner with trusted manufacturers to avoid counterfeit components in critical applications.
