Key Features
- 72-position dual-row terminal strip on a 0.100 inch (2.54 mm) pitch for high-density board-level signal and power interfaces
- Flash gold over nickel (FM) contact finish provides reliable low-oxidation mating performance across 72 positions
- Tape-and-reel (TR) packaging supports automated pick-and-place on high-volume SMT production lines without manual handling
- Dual-row (DH) configuration maximizes contact count within a standard 2.54 mm pitch SMT footprint for space-constrained boards
Applications
The TSM-136-01-FM-DH-A-P-TR is suited for backplane interconnects, FPGA expansion cards, and industrial automation controller boards requiring a 72-position 2.54 mm pitch SMT terminal strip. Its large 72-pin dual-row layout covers extensive signal and power routing requirements in data acquisition systems, communications equipment, and test-and-measurement platforms where high I/O density is critical.

Frequently Asked Questions
What is the total pin count and pitch of the TSM-136-01-FM-DH-A-P-TR, and how does the dual-row layout maximize board density?
The TSM-136-01-FM-DH-A-P-TR provides 72 positions in a dual-row (DH) layout on a 0.100 inch (2.54 mm) pitch, placing 36 contacts per row. This dual-row arrangement delivers 72 total contacts in the same PCB length as a 36-pin single-row strip, doubling I/O density for backplane and FPGA expansion card designs.
What does the FM contact finish option mean for the TSM-136-01-FM-DH-A-P-TR, and when is it preferred over full gold plating?
The FM designation specifies a flash gold over nickel barrier finish, which is a thin gold layer deposited over nickel on the 72 contact positions. It provides sufficient oxidation resistance for moderate-cycle mating applications at a lower cost than thick hard gold. FM finish is preferred when the connector will undergo fewer than a few hundred mating cycles in benign industrial or lab environments.
For a 72-pin backplane connector on a data acquisition system, how does the TSM-136-01-FM-DH-A-P-TR compare to a through-hole 72-pin strip?
Choosing the TSM-136-01-FM-DH-A-P-TR eliminates 72 through-holes, reducing PCB drilling cost and enabling single-pass SMT reflow without wave soldering. The 2.54 mm pitch footprint is compatible with standard 0.100 inch receptacles, and the tape-and-reel packaging supports automated placement of the 72-position connector on high-volume production lines.
Is the TSM-136-01-FM-DH-A-P-TR suitable for high-volume automated SMT production, and what packaging does it use?
Yes, the TR suffix confirms tape-and-reel packaging, making the TSM-136-01-FM-DH-A-P-TR directly compatible with standard pick-and-place equipment. SAMTEC's TSM series is stocked globally, with the 72-position 2.54 mm pitch strip available from authorized distributors and factory lead times typically ranging from 1 to 4 weeks for production quantities.
