What are the key features of TSM-126-04-TM-DH-P-TR?
- 52 positions in quad-row .100" (2.54 mm) pitch for very high pin density in a compact footprint
- Quad-row (04) configuration increases contact count without extending connector length
- Through-hole anchor pins (DH) provide superior mechanical retention under vibration and mechanical stress
- Polarized (P) design prevents incorrect connector mating in multi-connector assemblies
- Tape-and-reel (TR) packaging optimized for automated high-volume SMT assembly
What is TSM-126-04-TM-DH-P-TR used for?
The TSM-126-04-TM-DH-P-TR is designed for high pin count board-to-board interconnects in industrial control systems, server modules, and signal-dense embedded computing platforms. Its quad-row 52-position layout and through-hole anchor pins make it an excellent choice for ruggedized applications requiring both high signal density and strong mechanical retention, such as backplane systems and embedded module carrier boards.

Frequently Asked Questions
What distinguishes the quad-row (04) configuration of TSM-126-04-TM-DH-P-TR from dual-row TSM-126 variants?
The 04 designation in TSM-126-04-TM-DH-P-TR indicates a quad-row contact arrangement, delivering 52 positions across 4 rows at .100" (2.54 mm) pitch. This provides significantly higher pin density than a 2-row design for the same connector body length, allowing engineers to route more signal lines in applications where board space along the connector edge is limited.
How does the polarization (P) feature prevent costly wiring errors during TSM-126-04-TM-DH-P-TR field installation?
The P (polarized) keying physically blocks mating connectors from being inserted in the wrong orientation. With 52 signal positions across 4 rows at .100" pitch, a reversed connection could short or misroute dozens of signal lines simultaneously. Polarization is therefore essential for field-serviceable systems where technicians may handle multiple similar connectors during maintenance.
In what industrial or computing environments is the TSM-126-04-TM-DH-P-TR most commonly specified?
The TSM-126-04-TM-DH-P-TR with through-hole anchor pins and quad-row 52-position layout is commonly specified for industrial automation PLCs, server expansion backplanes, and ruggedized embedded computing systems. Its operating temperature range of -55°C to +125°C and mechanical retention from the DH anchor pins make it well suited for environments with vibration, shock, or wide thermal cycling requirements.
What current rating applies per contact for TSM-126-04-TM-DH-P-TR and how should power routing be planned?
SAMTEC TSM-series .100" pitch connectors are typically rated at approximately 1 A per signal contact. For the TSM-126-04-TM-DH-P-TR's 52 positions, designers routing mixed signal and power lines should assign multiple adjacent contacts to power and ground paths, derate to 70-80% of maximum current, and verify thermal performance under continuous load to avoid connector body temperature rise.
