What are the key features of TSM-120-02-L-DH-P-TR?
- 40-position dual-row 0.100" pitch SMT terminal strip delivering high-density board-to-board signal routing in a 2-inch body
- Gold (10 µin) over nickel (50 µin) mating contacts provide low contact resistance and extended durability across thousands of mating cycles
- Tin-over-nickel barrier termination finish ensures reliable solderability and prevents tin whisker growth in lead-free assembly processes
What is TSM-120-02-L-DH-P-TR used for?
The TSM-120-02-L-DH-P-TR is designed for high-density board interconnect applications in industrial computing, data acquisition systems, and modular embedded platforms where 40 signals must be reliably distributed across a 2-inch connector span. Its gold-plated contacts and RoHS-compliant tin termination make it suitable for telecommunications backplanes, FPGA development boards, and high-reliability test instrumentation.

Frequently Asked Questions
What contact finish specification does the TSM-120-02-L-DH-P-TR use, and why does it matter for mating cycle life?
The TSM-120-02-L-DH-P-TR uses 10 microinches of gold over 50 microinches of nickel on the mating contacts, which delivers low contact resistance and protects against oxidation through thousands of insertion cycles. The tin-over-nickel barrier termination on the solder side prevents interdiffusion, keeping the 40-position connector reliable in long-service industrial equipment.
Which embedded or FPGA board designs benefit most from the TSM-120-02-L-DH-P-TR's 40-position count?
FPGA development boards and modular industrial SBCs that need to distribute 40 signals — such as data bus lines, GPIO, power rails, and control signals — across a single 2-inch dual-row header benefit most from the TSM-120-02-L-DH-P-TR. Its 0.100" pitch and SMT footprint allow compact daughtercard stacking with a minimal PCB area penalty compared to through-hole alternatives.
How does the 2-inch body length of TSM-120-02-L-DH-P-TR compare to shorter terminal strips when routing high-pin-count signals?
At 2 inches (50.8 mm) long, the TSM-120-02-L-DH-P-TR can accommodate all 40 positions in a single connector body, eliminating the need for two 20-position headers in series. This reduces the number of board-level components, lowers assembly cost per connection, and provides a more uniform impedance environment for signal integrity on data bus and control lines running at speeds up to tens of MHz.
