What are the key features of 5126-B7A2 PL?
- 26-way dual-row 2.54mm pitch right-angle through-hole socket from 3M 5100 Series enables reliable ribbon cable-to-board interfacing in space-constrained PCB edge applications
- Right-angle solder termination reduces connector height above PCB and allows horizontal cable routing parallel to the board surface, ideal for compact enclosure designs
- Compatible with standard IDC 26-pin ribbon cable plugs, supporting quick cable assembly and field replacement in test equipment and embedded systems
What is 5126-B7A2 PL used for?
The 3M 5126-B7A2 PL is commonly used to interface 26-conductor ribbon cables with PCBs in industrial control panels, embedded computer boards, and data acquisition systems. Its right-angle through-hole design routes cables parallel to the board, making it ideal for rack-mount enclosures with limited vertical clearance. The 2.54mm pitch ensures compatibility with the widely used 26-pin IDC cable standard in legacy and modern systems alike.

Frequently Asked Questions
How many pins does the 3M 5126-B7A2 PL have, and what pitch does it use?
The 3M 5126-B7A2 PL has 26 total pins arranged in 2 rows at a 2.54mm (0.100") pitch, conforming to the widely used standard IDC ribbon cable grid for 26-conductor cables.
Why would a designer select a right-angle orientation for the 5126-B7A2 PL over a vertical through-hole socket in a rack-mount system?
A right-angle orientation routes the ribbon cable horizontally along the PCB surface, reducing the total connector height above the board — important in rack-mount or panel-mount enclosures where the PCB-to-lid clearance is less than 20mm.
What soldering method and mechanical attachment apply to the 3M 5126-B7A2 PL, and how does this affect PCB manufacturing?
The 5126-B7A2 PL uses through-hole solder termination, requiring drilled PCB holes at 2.54mm pitch and wave-soldering or hand-soldering, providing strong mechanical pull-out strength ideal for applications with cable-stress or repeated connector mating cycles.
