What are the key features of T2M-125-01-L-D-TH-WT?

50-position dual-row through-hole connector at 0.100 inch pitch in a 2.191 inch body for high-density board-to-board interconnects
Matte tin over nickel contact termination provides reliable solderability in standard wave and selective solder processes
Dual-row (D) configuration reduces board edge length required compared to single-row headers carrying the same 50-pin count

What is T2M-125-01-L-D-TH-WT used for?

The T2M-125-01-L-D-TH-WT is used in backplane assemblies, industrial control boards, and embedded computing systems where a 50-position through-hole connector at 0.100 inch pitch is needed for mechanically robust signal distribution across mating card pairs. Its 2.191 inch body length and dual-row layout suit high-density I/O expansion cards, relay boards, and analog signal distribution panels that require a reliable, wave-solderable 50-pin interconnect.

Frequently Asked Questions

What is the contact count and body length of the T2M-125-01-L-D-TH-WT connector?

The T2M-125-01-L-D-TH-WT has 50 positions arranged in 2 rows at 0.100 inch (2.54 mm) pitch across a body length of 2.191 inches (55.65 mm). This makes it a mid-range density through-hole connector suitable for 50-line interfaces on boards where the 2.2-inch body length fits within the available PCB edge allocation.

Why is the matte tin over nickel contact finish on the T2M-125-01-L-D-TH-WT suitable for wave solder assembly?

Matte tin over nickel provides excellent wettability with standard SAC305 lead-free solder paste and wave solder baths, making the T2M-125-01-L-D-TH-WT straightforward to process in conventional through-hole assembly lines. The nickel barrier layer under the tin prevents copper migration into the tin surface, which improves long-term solder joint reliability for the 50-pin connector in industrial environments.

For a relay control board that needs to route 48 independent signals, how does T2M-125-01-L-D-TH-WT reduce PCB board edge usage?

With 50 positions in 2 rows at 0.100 inch pitch, the T2M-125-01-L-D-TH-WT occupies only 2.191 inches of board edge while routing all 48 signals plus 2 spare contacts. A single-row 0.100 inch alternative would need approximately 4.9 inches of board edge to carry the same 50 pins, more than double the space, making the dual-row T2M-125-01-L-D-TH-WT the more compact choice for dense relay panels.
