Key Features
- 46 positions in dual-row 0.100" (2.54 mm) pitch with single-row vertical (SH) tail orientation for versatile PCB integration
- Polarized (P) housing key prevents incorrect connector mating and reduces assembly errors in dense multi-connector boards
- Gold-plated contacts rated 350V AC and 3A per pin provide reliable power and signal connections across thousands of mating cycles
- Tape-and-reel (TR) packaging enables fully automated high-volume SMT pick-and-place assembly with standard reflow processes
Applications
TSM-123-05-TM-SH-P-TR is used in industrial control systems, embedded computing modules, and instrumentation boards requiring a high-pin-count 2.54 mm pitch polarized connector with surface mount convenience. The single-row vertical tail configuration enables right-angle daughter card installations, ideal for compact chassis designs and panel-mount controller boards. The polarized housing ensures correct orientation during field replacement of sub-assemblies in medical devices and test equipment.

Frequently Asked Questions
How many positions does the TSM-123-05-TM-SH-P-TR have and what pitch does it use?
The TSM-123-05-TM-SH-P-TR is a 46-position connector arranged in a dual-row layout at 0.100" (2.54 mm) pitch. This standard pitch ensures broad compatibility with industry-standard mating receptacles, headers, and IDC connectors, making it suitable for prototyping and production PCB designs requiring 46 signals in a compact surface mount footprint.
What voltage and current capacity does each contact in the TSM-123-05-TM-SH-P-TR support?
Each of the 46 contacts in the TSM-123-05-TM-SH-P-TR is rated for 350V AC working voltage and 3A continuous current. The gold-plated finish with 30 µin thickness ensures initial contact resistance below 20 mΩ, supporting both signal and low-voltage power distribution in industrial control boards operating at temperatures from -55°C to +125°C.
What does the SH tail configuration mean for PCB layout of the TSM-123-05-TM-SH-P-TR?
The SH designation in TSM-123-05-TM-SH-P-TR indicates a single-row vertical through-hole tail orientation. This configuration positions the solder tails in a single line along the connector length, simplifying PCB routing by keeping solder pads to one side and providing mechanical anchoring through soldered through-hole tails, which is beneficial in vibration-prone environments rated up to 85°C ambient.
When should a designer select TSM-123-05-TM-SH-P-TR over a non-polarized version?
Designers choose the polarized (P) variant TSM-123-05-TM-SH-P-TR when mating with systems where reverse insertion would damage circuitry or cause functional failure. In 46-position dual-row connectors at 2.54 mm pitch, physical symmetry makes accidental reversal easy; the P keying adds a mechanical blockout that prevents misinsertion on the production floor and during field servicing of industrial and medical equipment.
What alternative SAMTEC part could replace the TSM-123-05-TM-SH-P-TR if tape-and-reel packaging is not needed?
If tape-and-reel packaging is not required, the TSM-123-05-TM-SH-P (without the TR suffix) provides the identical 46-position, 0.100" pitch, dual-row, polarized, SH tail connector in tray or tube packaging. Both variants share the same electrical ratings of 350V AC and 3A per pin, and the same PCB footprint, allowing flexible procurement based on assembly line requirements.
