What are the key features of TSM-140-04-H-DV-P-TR?
- 80-position dual-row SMT terminal strip at 0.100" (2.54 mm) pitch delivering 40 pins per row for dense backplane and daughter-card signal distribution with up to 3 A per pin
- High-retention (-H suffix) contact geometry maintaining secure engagement across 50+ mating cycles at contact resistance below 20 mΩ for robust industrial interconnects
- Gold-plated contact finish minimizing contact resistance and protecting against oxidation in humid or chemically aggressive environments over the -40°C to +105°C operating range
What is TSM-140-04-H-DV-P-TR used for?
The TSM-140-04-H-DV-P-TR is designed for industrial control modules, PLC backplanes, and embedded computing boards requiring a robust 80-position dual-row 0.100" SMT terminal strip with high-retention contacts. Its 3 A per pin rating and gold plating make it suitable for mixed signal and power distribution in rugged automation equipment subject to vibration and temperature cycling. The tape-and-reel format supports high-volume automated assembly of communication hardware, test equipment, and motor control cards.

Frequently Asked Questions
What current rating does each pin of the TSM-140-04-H-DV-P-TR support?
Each pin of the TSM-140-04-H-DV-P-TR is rated at up to 3 A, and the connector provides 80 total positions in 2 rows at 0.100" (2.54 mm) pitch. This supports mixed routing of power supply rails and digital signals across a single 80-pin dual-row SMT footprint in industrial backplane designs.
What does the -H suffix indicate on TSM-140-04-H-DV-P-TR, and does it affect mating cycle life?
The -H suffix denotes high-retention contact geometry, which increases the normal force at each of the 80 contact points for a more secure mating engagement. This enhances resistance to vibration-induced disconnection and extends rated mating cycle life to 50+ insertions, compared to 25 cycles for standard-retention TSM variants, making it preferable for field-serviceable industrial modules.
How does TSM-140-04-H-DV-P-TR compare to TSM-140-01-F-DV-P-TR for an industrial automation design?
Both are 80-position dual-row 0.100" (2.54 mm) pitch SMT terminal strips in tape-and-reel packaging. TSM-140-04-H-DV-P-TR uses gold-plated contacts with high-retention (-H) geometry rated for 3 A per pin and 50+ mating cycles, while TSM-140-01-F-DV-P-TR uses tin-plated contacts with standard retention rated for lower current. Choose the -04-H variant for rugged industrial environments requiring higher current capacity and repeated mating under vibration.
Can TSM-140-04-H-DV-P-TR be soldered in a standard SMT reflow process?
Yes, TSM-140-04-H-DV-P-TR is fully compatible with standard SMT reflow soldering up to 260°C peak temperature. The tape-and-reel (TR) packaging ensures consistent component orientation during automated pick-and-place at high production throughputs, and the surface-mount termination eliminates the need for through-hole drilling on 80-pin dual-row PCB layouts.
