What are the key features of HTSS-126-01-TM-DV-P-TR?
- 52-position dual-row layout at 0.100 inch (2.54mm) pitch provides high-density signal connectivity in a single connector footprint, reducing board connector count
- High-temperature shroud construction maintains dimensional stability and contact retention at operating temperatures up to 105°C or higher, suitable for industrial and automotive adjacency environments
- Polarized shroud prevents incorrect cable-mate mating orientation, protecting signal lines from mis-connection damage during field installation and maintenance
- Tape-and-reel (TR) packaging enables automated pick-and-place SMT assembly for high-volume production with consistent placement accuracy
- SAMTEC cable-mate compatibility ensures direct coupling with matching HTSD or HTSL series cable assemblies for reliable harness-to-board interconnection
What is HTSS-126-01-TM-DV-P-TR used for?
The HTSS-126-01-TM-DV-P-TR is used in industrial control systems, test and measurement equipment, and power distribution boards where a high-density 52-position cable-to-board interface at 0.100 inch pitch is required in elevated-temperature environments. Its shrouded polarized design suits rack-mount servers, motor drive panels, and PLC backplanes that need repeatable, keyed connections for field-installable ribbon cable harnesses. The tape-and-reel SMT form factor also makes it suitable for high-volume board assembly in telecommunications infrastructure and automation equipment.

Frequently Asked Questions
How many positions does the HTSS-126-01-TM-DV-P-TR provide, and how are they arranged across the connector body?
The HTSS-126-01-TM-DV-P-TR has 52 positions arranged in a dual-row (DV) configuration at 0.100 inch (2.54mm) pitch, giving 26 pins per row. This dual-row layout at 2.54mm pitch provides a compact 52-signal interface in a connector body approximately 32.5mm long, making it practical for high-density cable harness connections on backplane PCBs, industrial I/O modules, and embedded computing boards where parallel signal buses require a reliable multi-position connector.
What is the pitch of the HTSS-126-01-TM-DV-P-TR and how does it affect cable assembly compatibility?
The HTSS-126-01-TM-DV-P-TR uses a 0.100 inch (2.54mm) contact pitch, which is the standard pitch for IDC ribbon cable assemblies and discrete wire harnesses using 26 AWG to 30 AWG conductors. This pitch directly mates with SAMTEC's HTSD and HTSL series 52-position cable assemblies, and is also compatible with industry-standard 52-pin ribbon cable connectors from other manufacturers at the same 2.54mm pitch. The 2.54mm spacing allows current ratings of approximately 1A to 3A per pin depending on conductor gauge and ambient temperature.
What temperature rating does the HTSS-126-01-TM-DV-P-TR's high-temp shroud provide, and which applications benefit from this?
The high-temperature shroud in the HTSS-126-01-TM-DV-P-TR is constructed from a thermoplastic rated for continuous operation at temperatures up to at least 105°C, with short-term tolerance above 125°C during soldering reflow. This rating suits industrial motor drive enclosures, power electronics cabinets, and automotive underhood-adjacent applications where ambient temperatures exceed the 85°C limit of standard thermoplastic connectors. The elevated temperature rating prevents shroud deformation and contact loosening in environments where heat from nearby power components raises local PCB temperature above standard connector limits.
How does the polarized shroud on the HTSS-126-01-TM-DV-P-TR prevent mis-mating in field-installed cable harnesses?
The shroud on the HTSS-126-01-TM-DV-P-TR includes a mechanical key or asymmetric polarization feature that aligns with the matching key slot on the SAMTEC cable-mate housing, preventing the 52-position connector from being inserted in the wrong orientation or offset by 2 rows. On a 52-pin dual-row connector at 2.54mm pitch, a single-row offset mis-connection would cross 26 signals, which could damage ICs operating at 3.3V or 5V logic levels. The polarization eliminates this risk during field service where technicians may connect harnesses without referencing pin-1 markers.
Is the HTSS-126-01-TM-DV-P-TR suitable for automated SMT production, and what reel format does it ship in?
Yes, the HTSS-126-01-TM-DV-P-TR ships in tape-and-reel (TR) format for automated SMT pick-and-place assembly, with a carrier tape pitch and pocket size matched to the connector body dimensions for reliable feeder operation. Tape-and-reel packaging allows placement rates consistent with other SMT components at 2,000 to 5,000 components per hour on standard SMT lines, and the consistent component orientation in the tape ensures that pin 1 is always positioned correctly for automatic polarity alignment. This format supports JIT production scheduling for board builds in quantities from a few hundred to tens of thousands of units.
