Frequently Asked Questions
What is the pin count and pitch of the TSM-120-02-L-DH-A-K-TR connector?
The TSM-120-02-L-DH-A-K-TR features 40 positions arranged in a dual-row configuration with a 0.100" (2.54 mm) pitch. This standard spacing is compatible with a wide range of mating connectors and PCB footprints used in industrial and commercial electronics designs.
Which PCB assembly processes are supported by the TSM-120-02-L-DH-A-K-TR packaging format?
The TR suffix designates tape-and-reel packaging, enabling automated SMT pick-and-place assembly at high volumes. The component is rated for surface mount soldering, and its 2.54 mm pitch accommodates standard reflow profiles at temperatures up to 260°C per IPC/JEDEC J-STD-020 guidelines.
When would an engineer choose TSM-120-02-L-DH-A-K-TR over a single-row strip in a backplane design?
A dual-row terminal strip like the TSM-120-02-L-DH-A-K-TR is preferred when board real estate is limited and 40 pins must be routed in a compact footprint, cutting connector length roughly in half compared to a single-row 40-pin strip. This is especially beneficial in 19-inch rack equipment and compact embedded modules where PCB width is constrained to under 100 mm.
What contact plating does the TSM-120-02-L-DH-A-K-TR use and why does it matter for signal integrity?
The TSM-120-02-L-DH-A-K-TR uses gold (Au) contact plating, typically 30 µin minimum per SAMTEC's standard finish specification. Gold plating provides contact resistance below 20 mΩ and prevents oxidation, making it suitable for low-level signal applications and repeated mating cycles exceeding 100 insertions.
