What are the key features of TFM-120-01-L-D-RE2-WT?
- 40 dual-row contacts on 1.27 mm pitch in a right-angle receptacle profile, enabling edge-mount board-to-board or wire-to-board connections with a low 8 mm above-board height
- Gold (15 µin) over nickel (50 µin) mating contact finish delivers low contact resistance and >1000 mating-cycle durability for reliable high-density signal routing
- Integrated weld-tab retention tabs mechanically anchor the connector to the PCB, reducing solder-joint stress in vibration-prone environments and eliminating additional hold-down hardware
What is TFM-120-01-L-D-RE2-WT used for?
The TFM-120-01-L-D-RE2-WT is designed for right-angle board-to-board stacking in embedded computing, industrial control, and test-and-measurement equipment where 40 signals must exit the PCB edge in a 1.27 mm pitch footprint. Its receptacle body style and weld-tab retention make it a reliable choice for daughter-card and backplane interfaces in compact rack-mount chassis where vibration resistance is required. The RoHS-compliant tin-terminated leads are compatible with standard lead-free reflow soldering processes used in medical device and telecommunications hardware.

Frequently Asked Questions
How many contacts and at what pitch does the TFM-120-01-L-D-RE2-WT provide?
The TFM-120-01-L-D-RE2-WT features 40 contacts arranged in 2 rows on a 1.27 mm (0.050 inch) pitch, for a total connector body length of approximately 1.263 inches (32.1 mm). This dual-row configuration on a tight pitch supports high-density signal routing in embedded computing and industrial control daughter cards where board real estate is limited.
What contact finish does the TFM-120-01-L-D-RE2-WT use and why does it matter for mating reliability?
The mating contacts are finished with 15 µin gold over 50 µin nickel, a combination that provides low and stable contact resistance — typically under 20 mΩ — and supports more than 1000 mating cycles. The nickel barrier prevents gold diffusion into the base metal, maintaining reliable electrical continuity in high-cycle applications such as test-fixture spring probes, removable daughter boards, and field-replaceable modules.
Why choose the TFM-120-01-L-D-RE2-WT right-angle version over a vertical receptacle for edge-mounted boards?
The right-angle (RE2) orientation routes signals parallel to the PCB surface, allowing the mating cable or board to exit horizontally from the chassis edge. This reduces the above-board height to approximately 8 mm versus a vertical header's 12–15 mm, a critical advantage in low-profile rack-mount or panel-mounted enclosures. The weld-tab design also adds mechanical retention without extra hardware when mounting to 1.6 mm standard PCB thickness.
Is the TFM-120-01-L-D-RE2-WT compatible with lead-free reflow soldering and RoHS regulations?
Yes, the TFM-120-01-L-D-RE2-WT is explicitly marked RoHS compliant and uses tin-with-nickel-barrier termination on its PCB tails, which is fully compatible with lead-free SAC305 solder paste at reflow peak temperatures up to 260°C. Its 1-week factory lead time and RoHS status make it suitable for regulated end products in medical, telecommunications, and EU-market industrial equipment requiring REACH and RoHS documentation.
