What are the key features of TSM-120-04-T-DH-A-K-TR?
- 40-position dual-row SMT terminal strip with 0.100" (2.54 mm) pitch in right-angle orientation for horizontal mating interface
- Gold (Au) plated contacts deliver contact resistance below 20 mΩ and support over 100 mating cycles for durable interconnect reliability
- Tape-and-reel (TR) packaging facilitates automated pick-and-place assembly at high throughput with zero feed interruptions
What is TSM-120-04-T-DH-A-K-TR used for?
The TSM-120-04-T-DH-A-K-TR is suited for horizontal board-to-board interconnect in rack-mount systems, backplane assemblies, and modular industrial controllers where the right-angle contact style allows parallel PCB stacking. Its 40-pin dual-row configuration supports high-density signal routing in embedded computing modules, test fixtures, and communication interface boards. The tape-and-reel format makes it a practical choice for high-volume SMT production lines in telecom and defense electronics.

Frequently Asked Questions
How does the right-angle contact style of TSM-120-04-T-DH-A-K-TR benefit horizontal PCB-to-PCB stacking designs?
The T (right-angle) contact orientation routes signals horizontally from the PCB edge, reducing the vertical stack height in multi-board assemblies to as little as 5 mm. This is critical in 1U rack systems and compact embedded modules where vertical clearance is limited, and the 0.100" (2.54 mm) pitch provides 40 reliable signal paths per connector.
What soldering process and peak reflow temperature does TSM-120-04-T-DH-A-K-TR support?
The TSM-120-04-T-DH-A-K-TR is designed for SMT reflow soldering with a peak temperature of 260°C, compliant with JEDEC J-STD-020 MSL requirements. The tape-and-reel packaging ensures consistent component orientation through automated pick-and-place, supporting high-volume production at reflow conveyor speeds typical of industrial SMT lines.
Is TSM-120-04-T-DH-A-K-TR a suitable drop-in alternative to TSM-120-02-L-DH-A-K-TR in the same footprint?
No — the TSM-120-04-T-DH-A-K-TR uses a right-angle (T) contact orientation while the TSM-120-02-L-DH-A-K-TR uses a vertical (L) style, so the PCB footprint and mating direction differ. Both share the same 40-position, 2.54 mm dual-row layout and gold contact plating, but the right-angle variant requires a different land pattern and mating connector approach.
For a 40-signal bus interface at 3.3 V logic, what current rating can each contact of TSM-120-04-T-DH-A-K-TR handle?
SAMTEC TSM series contacts are rated at 1 A per contact for signal-level currents, with gold plating providing stable low-resistance connections at 3.3 V logic levels. For a 40-contact bus carrying mixed signal and power, designers typically derate to 0.5 A per pin to maintain thermal margin when all 40 positions are simultaneously active in dense routing scenarios.
