Key Features
- 44-position dual-row SMT terminal strip on 0.100 inch (2.54 mm) standard pitch
- Right-angle (L) through-hole tails with dual-height (DH) insulator for board-edge mounting
- Polarization key (K option) and gold-plated contacts ensure correct mating and low contact resistance
- Tape-and-reel (TR) format enables high-volume automated pick-and-place SMT assembly
Applications
The TSM-122-04-L-DH-A-K-TR is suited to board-edge signal headers in embedded computing, industrial I/O panels, and test instrumentation where a right-angle 44-position 0.100-inch connector routes signals parallel to the PCB surface. Its dual-height insulator provides standoff clearance for routing traces beneath the connector body, and the key option prevents incorrect mating during field maintenance. High-volume manufacturing benefits from the tape-and-reel format and compatibility with standard IDC ribbon cable assemblies.

Frequently Asked Questions
What does the L suffix mean in TSM-122-04-L-DH-A-K-TR and how does it affect board layout?
The L suffix in TSM-122-04-L-DH-A-K-TR designates a right-angle lead style, meaning the through-hole tails exit at 90 degrees relative to the insulator body. This right-angle orientation places the mating direction parallel to the PCB plane, making it ideal for board-edge connectors in enclosures where vertical mating height is limited to less than 10 mm.
How many signal positions does TSM-122-04-L-DH-A-K-TR offer and how is it laid out across rows?
TSM-122-04-L-DH-A-K-TR provides 44 positions arranged as 2 rows of 22 pins on a 0.100-inch (2.54 mm) pitch. This dual-row configuration allows 44 signals in the same board footprint length as a single-row 22-pin header, making it a space-efficient choice for industrial control boards and backplane expansion connectors.
Can TSM-122-04-L-DH-A-K-TR mate with standard 2.54 mm IDC ribbon cable assemblies?
Yes, the TSM-122-04-L-DH-A-K-TR is compatible with standard 44-pin IDC ribbon cable connectors on 2.54 mm pitch. The polarization key (K suffix) ensures correct insertion direction when mating with a corresponding keyed IDC socket, reducing risk of reversed connections. Maximum current per pin is rated for signal-level loads typical of 3.3 V or 5 V digital I/O lines carrying up to several hundred milliamps.
Is TSM-122-04-L-DH-A-K-TR an alternative to TSM-122-04-TL-DH-A-K-TR, and what changes?
TSM-122-04-L-DH-A-K-TR differs from TSM-122-04-TL-DH-A-K-TR only in the tail orientation: the L version uses right-angle tails while TL denotes a vertical through-hole tail configuration. Both have the same 44-position, 2.54 mm dual-row layout and identical electrical ratings; the choice depends on whether the cable or mating connector exits perpendicular or parallel to the PCB surface.
