What are the key features of HTSS-128-01-LM-DV-P-TR?
- 56-position dual-row configuration at 2.54mm (0.100 inch) pitch provides a high-density cable-mate interface on a standard footprint
- High-temperature rated shrouded body protects contacts and ensures reliable mating in elevated ambient conditions up to industrial temperature limits
- Polarized shroud with dual-row housing prevents reversed insertion, reducing assembly errors in high-volume automated production
What is HTSS-128-01-LM-DV-P-TR used for?
The HTSS-128-01-LM-DV-P-TR is used in industrial control panels, test and measurement equipment, and embedded computing backplanes where a large number of signal lines must be routed reliably from board to cable in high-temperature operating environments. Its dual-row 56-position layout at 0.100 inch pitch allows engineers to consolidate many signal and power lines into a single polarized connector, simplifying wiring harness management and reducing assembly errors in automated manufacturing.

Frequently Asked Questions
How many positions and what pitch does the HTSS-128-01-LM-DV-P-TR provide, and how does this affect connector density?
The connector provides 56 positions arranged in 2 rows at a 2.54mm (0.100 inch) pitch. This dual-row layout at 0.100 inch spacing means 56 signal lines occupy roughly the same PCB length as 28 single-row contacts, halving the linear footprint needed for a given channel count compared to single-row 0.100 inch strip connectors.
What makes this connector suitable for high-temperature environments compared to standard shrouded headers?
The HTSS series from SAMTEC uses high-temperature thermoplastic housing materials rated for elevated ambient conditions beyond the typical 85°C limit of standard connectors. This makes the HTSS-128-01-LM-DV-P-TR appropriate for applications near heat sinks, power electronics, or enclosed equipment bays where internal temperatures can reach 105°C or higher during sustained operation.
Does the polarized shroud on this connector prevent incorrect cable installation, and how?
Yes. The shroud includes a keying feature and physical polarization tab that allows the mating cable connector to insert in only one orientation. This prevents the 56-pin cable harness from being installed 180 degrees reversed, which would short signal lines to ground or apply reverse voltage across sensitive ICs. Polarization is especially valuable in field service scenarios where technicians may be swapping cables in low-visibility enclosures.
What packaging format does the HTSS-128-01-LM-DV-P-TR come in, and why is that beneficial for SMT production lines?
The TR suffix indicates tape-and-reel packaging, which feeds the connector into pick-and-place machines at standard 0.100 inch carrier pitch increments. Tape-and-reel eliminates manual part loading, reduces handling damage, and supports automated optical inspection (AOI) placement verification. For high-volume PCB assembly producing thousands of units, tape-and-reel can cut per-board connector assembly time by 30–60 seconds compared to tube or tray formats.
