Frequently Asked Questions
What contact pitch and row configuration does the TFM-125-32-S-D use?
The TFM-125-32-S-D uses a 0.050" (1.27 mm) pitch in a single-row, 50-position receptacle configuration. This fine pitch allows high-density placement on PCBs with limited board space, making it suitable for compact electronic designs requiring reliable signal interconnects.
What contact finish does the TFM-125-32-S-D provide and why does it matter for signal reliability?
The TFM-125-32-S-D features 30 µin gold over 50 µin nickel contact finish on the mating interface, with matte tin over nickel on the termination side. This gold plating ensures low contact resistance, excellent corrosion resistance, and stable performance over thousands of mating cycles in demanding environments.
In which applications is the TFM-125-32-S-D connector typically deployed?
This connector is used in high-reliability applications such as telecommunications backplane assemblies, medical diagnostic devices, and industrial automation control boards. Its shrouded receptacle design with Tiger Eye contacts and ELP feature supports secure board-to-board connections in systems requiring 1.27 mm pitch density with long service life.
How does the TFM-125-32-S-D compare to non-shrouded terminal strips of the same pitch?
Unlike standard open terminal strips, the TFM-125-32-S-D includes a shrouded body measuring approximately 1.375 inch body length and 0.44 inch depth, providing guided mating alignment. This reduces the risk of mis-mating and pin damage, especially in automated assembly and field-service environments where multiple 50-position contacts must engage simultaneously.
