Frequently Asked Questions
What is the contact pitch and row configuration of the TFM-138-02-L-D?
The TFM-138-02-L-D features a 0.050 inch (1.27 mm) pitch with a dual-row rectangular contact pattern, providing 38 positions per row for a total of 76 contacts. This tight pitch enables high-density interconnects on compact PCBs.
Which mating contact finish does the TFM-138-02-L-D use and why does it matter for signal integrity?
The TFM-138-02-L-D uses gold-over-nickel (AU ON NI) mating contact finish, which delivers low contact resistance typically below 20 milliohms and excellent corrosion resistance over thousands of mating cycles. This finish is critical for maintaining signal integrity in high-reliability and high-cycle applications.
In what types of board stacking assemblies is the TFM-138-02-L-D typically used?
The TFM-138-02-L-D is used in board-to-board mezzanine stacking assemblies, embedded computing modules, industrial backplanes, and test-and-measurement fixtures. Its 0.050" pitch and 76-contact dual-row configuration supports high pin-count interconnects in compact spaces of 2.025 inches body length.
What are the body dimensions of the TFM-138-02-L-D connector?
The TFM-138-02-L-D has a body length of 2.025 inches and a body breadth of 0.225 inches, accommodating 38 dual-row positions at 0.050" pitch. These compact dimensions allow integration in space-constrained PCB layouts typical of embedded and modular system designs.
