What is QSE-020-01-L-D-A-K-TR used for?
The QSE-020-01-L-D-A-K-TR is used in board-stacking architectures for embedded computing modules, industrial controller expansion boards, and test-and-measurement equipment where a 40-pin dual-row interface must reliably interconnect two PCBs. Its positioning pin design is particularly valuable in robotics and industrial automation systems requiring repeatable board alignment during field maintenance. The tape-and-reel format enables efficient automated SMT assembly in high-volume production of networking, telecom, and modular embedded platform hardware.

Frequently Asked Questions
How many positions and what pitch does the SAMTEC QSE-020-01-L-D-A-K-TR provide for board stacking applications?
The QSE-020-01-L-D-A-K-TR is a 40-position dual-row socket connector with 20 contacts per row arranged on a 0.100 inch (2.54 mm) pitch. This standard pitch ensures compatibility with SAMTEC's mating QSH or equivalent stacking header series, enabling reliable 40-signal board-to-board connections in compact embedded computing and expansion card designs.
What role do the positioning pins play in QSE-020-01-L-D-A-K-TR board assembly, and what tolerances do they support?
The positioning pins in the QSE-020-01-L-D-A-K-TR mechanically register the connector body to corresponding PCB holes, typically 1.02 mm diameter, before soldering, ensuring the 40 contacts align accurately with their PCB pads during wave or reflow solder operations. This reduces co-planarity errors to within 0.1 mm, which is critical for achieving reliable solder joints across all 40 positions in automated SMT assembly environments.
In what stacked-board system configurations is the QSE-020-01-L-D-A-K-TR commonly used, and how does its body height affect overall stack-up?
The QSE-020-01-L-D-A-K-TR with a body depth of 0.12 inch is used in processor-to-peripheral board stacking configurations, such as CPU modules mating with I/O expansion boards in embedded industrial computers and SBC (single board computer) systems. The low 0.12-inch socket body height, combined with the mating header stack height, allows designers to achieve compact inter-board spacing, keeping the total PCB stack below 10 mm in many form factors.
When should a designer select the QSE-020-01-L-D-A-K-TR over a comparable wire-to-board connector for a 40-signal interconnect?
The QSE-020-01-L-D-A-K-TR is preferred over wire-to-board alternatives when two PCBs must be mechanically stacked in a fixed spatial relationship, eliminating harness routing complexity and reducing overall assembly height. It supports 40 signals at 0.100 inch pitch in a body measuring only 0.837 inch long by 0.285 inch wide, offering a far more compact footprint than a 40-pin IDC harness connector, which would add 10 mm or more in both cable volume and routing overhead.
