What are the key features of TSM-126-05-TM-SH-A?
- 26-position dual-row layout on 0.100 inch pitch packing 26 signals into a compact surface-mount footprint
- Shrouded single-row horizontal housing for guided mating that prevents mis-insertion in field-serviceable assemblies
- Surface-mount termination (TM suffix) enabling automated reflow soldering compatible with standard SMT production lines
- Robust tin-plated contacts designed for reliable electrical connection across thousands of mating cycles in industrial environments
What is TSM-126-05-TM-SH-A used for?
The TSM-126-05-TM-SH-A is deployed in embedded computing modules, industrial I/O expansion boards, and test fixture PCBs where a 26-pin dual-row 0.100 inch SMT connector must survive vibration and repeated mating cycles. The shrouded horizontal housing aligns easily with matching receptacles on daughtercard and backplane interfaces, reducing field mis-wiring risk in rack-mounted equipment. It is also used in robotics and PLC systems requiring a compact, RoHS-compatible connector that can be placed and soldered with standard pick-and-place machinery.

Frequently Asked Questions
How many signal positions does the TSM-126-05-TM-SH-A provide, and what is its contact pitch?
The TSM-126-05-TM-SH-A provides 26 positions arranged in a dual-row configuration on a standard 0.100 inch (2.54 mm) pitch. This gives 13 positions per row, allowing 26 independent signals or mixed power and signal lines in a footprint compatible with common 2.54 mm grid PCB layouts used across industrial and computing applications.
What termination style does the TSM-126-05-TM-SH-A use, and how does it integrate into an SMT assembly process?
The TM suffix designates surface-mount termination, so the connector's leads are soldered directly to PCB pads during reflow. It is compatible with standard no-clean solder paste and reflow profiles up to 260 °C peak temperature. This eliminates the need for through-hole drilling, reduces board thickness constraints, and allows the part to be handled by automated pick-and-place equipment in high-volume SMT production lines.
For which applications is the TSM-126-05-TM-SH-A shrouded design an advantage over an unshrouded dual-row header?
The shrouded housing physically guides the mating connector onto all 26 pins simultaneously, preventing single-row offset mis-mating that can damage contacts or create intermittent connections. This is critical in field-serviceable rack modules, robotics end-effector boards, and industrial PLC I/O cards that are disconnected and reconnected during maintenance, where a technician may otherwise misalign an unshrouded 26-pin, 0.100 inch header under time pressure.
Can the TSM-126-05-TM-SH-A carry mixed power and signal loads, and what current per contact is typical for SAMTEC .100 inch series?
Yes, SAMTEC's 0.100 inch TSM series contacts are rated for approximately 3 A per pin when used with appropriate wire gauge and PCB trace widths. In a 26-position connector, designers commonly dedicate 2 to 4 pins to power rails (for example, 3.3 V or 5 V) at up to 6 A aggregate, while the remaining 22 to 24 pins carry digital or analog signals. Derating to 1 A per contact is recommended when ambient temperature exceeds 70 °C.
