What are the key features of TSM-120-03-TL-DH-P-TR?
- 40-position triple-row layout at 2.54 mm (0.100 inch) pitch providing 120 total contacts
- TL contact style with dual-height (DH) design for flexible mating connector height compatibility
- Tape-and-reel (TR) packaging enables automated SMT pick-and-place assembly for high-volume production
- Triple-row surface mount design maximizes contact density within a compact PCB footprint
- Standard 2.54 mm pitch ensures compatibility with the widest range of mating headers and socket strips
What is TSM-120-03-TL-DH-P-TR used for?
The TSM-120-03-TL-DH-P-TR is commonly used in industrial backplane connectors, embedded computing expansion sockets, and high-density control module interfaces where 120 contacts across 40 triple-row positions at 2.54 mm pitch provide comprehensive multi-bus signal routing. The triple-row configuration is preferred in VME backplane designs, industrial automation controllers, and data acquisition systems that require more than 80 contacts while keeping connector length under 110 mm. Tape-and-reel packaging supports seamless integration into automated SMT assembly lines for volume manufacturing.

Frequently Asked Questions
How many total contacts does the TSM-120-03-TL-DH-P-TR provide, and what PCB footprint length does the triple-row layout require?
The TSM-120-03-TL-DH-P-TR provides 120 total contacts in a triple-row, 40-position layout at 2.54 mm (0.100 inch) pitch. The connector footprint spans approximately 102 mm in length, allowing high contact density in backplane and expansion bus PCBs while fitting within standard board edge dimensions common in industrial control and embedded computing designs.
What does the TL contact style mean for the TSM-120-03-TL-DH-P-TR in terms of mating connector compatibility?
The TL contact designation in the TSM-120-03-TL-DH-P-TR indicates a specific contact geometry with a longer overall contact length for increased normal force and improved mating stability. Combined with the dual-height (DH) feature, TL contacts accommodate a wider range of mating socket heights, typically from 7 mm to 15 mm stack height, reducing the need for exact-match mating connectors in multi-generation product designs.
For which types of industrial and backplane applications is a triple-row 2.54 mm pitch terminal strip preferred over a dual-row design?
Triple-row terminal strips like the TSM-120-03-TL-DH-P-TR are preferred when designs require 100 or more contacts within a connector length of 110 mm or less. In VME backplane, industrial PLC bus, and multi-channel data acquisition designs, 120 contacts across 3 rows at 2.54 mm pitch reduce PCB length by over 30% compared to a 2-row solution at the same pitch, enabling more compact controller and I/O module form factors.
Does the tape-and-reel packaging of the TSM-120-03-TL-DH-P-TR support lead-free reflow soldering in RoHS-compliant assembly?
Yes. The TSM-120-03-TL-DH-P-TR with tape-and-reel (TR) packaging is compatible with automated SMT pick-and-place machines and standard lead-free reflow soldering profiles peaking at 260°C. This makes it suitable for RoHS-compliant PCB production lines in industrial electronics, embedded computing, and communications equipment manufacturing where 120-contact triple-row surface mount connectors are assembled at high volume.
