HTSS-133-01-SM-DV SAMTEC Connector (Other) In Stock
The HTSS-133-01-SM-DV is a 66-position dual-row high-temperature shrouded terminal strip from SAMTEC with 0.100 inch (2.54mm) pitch, designed for direct cable-mate mating in industrial and elevated-temperature environments. Its shrouded polarized housing prevents mis-mating and protects 66 contacts across two rows from mechanical damage during cable connection. Available in standard through-hole form factor for manual or semi-automated PCB assembly in demanding thermal applications.

What are the key features of HTSS-133-01-SM-DV?
- 66-position dual-row layout at 0.100 inch (2.54mm) pitch delivers one of the highest pin-count cable-mate interfaces in the HTSS series in a single connector body
- High-temperature thermoplastic shroud retains dimensional stability and contact integrity at continuous operating temperatures up to at least 105°C for industrial adjacency environments
- Polarized shroud housing prevents incorrect cable orientation on 66-pin harnesses, protecting logic and power lines from mis-connection damage during field service
- Through-hole termination style (SM designation) provides strong solder joint anchoring on PCBs subject to vibration in motor drive and industrial automation enclosures
- SAMTEC HTSD and HTSL series 66-position cable assemblies mate directly, enabling standardized harness-to-board connections without custom cable modifications
What is HTSS-133-01-SM-DV used for?
The HTSS-133-01-SM-DV is suited for high-pin-count cable-to-board interfaces on industrial PLC backplanes, servo drive controller boards, and rack-mount instrumentation requiring 66-signal connectivity at 0.100 inch pitch in environments above 85°C. Its through-hole mounting provides mechanical robustness for cable harnesses subject to pull and vibration loads in motor control panels and factory automation equipment. The 66-position dual-row layout also supports compact parallel bus interconnects in test systems and embedded computing modules where consolidating multiple lower-count connectors into a single 66-pin interface reduces PCB connector footprint.

Frequently Asked Questions
How many usable signal pins does the HTSS-133-01-SM-DV provide, and how are they physically arranged?
The HTSS-133-01-SM-DV provides 66 contact positions arranged in 2 rows of 33 pins each at a 0.100 inch (2.54mm) pitch. The total connector body length across 33 positions per row at 2.54mm pitch is approximately 82.5mm, making this one of the longer HTSS series housings. The dual-row configuration at 2.54mm pitch supports current ratings of approximately 1A to 3A per pin with 26 AWG to 30 AWG conductors in matched cable assemblies, enabling the 66-position connector to carry mixed power and signal assignments across the same harness.
What makes the HTSS-133-01-SM-DV's through-hole termination preferable to a surface-mount version for vibration-prone industrial enclosures?
The through-hole (SM) termination style of the HTSS-133-01-SM-DV creates solder fillets that encapsulate the full pin length through the PCB, providing pull-out strength typically exceeding 20N per pin compared to 5N to 10N for SMT pad solder joints. In motor drive panels and automation equipment subject to vibration amplitudes of 2g to 10g at 10Hz to 500Hz, through-hole joints resist fatigue cracking significantly better than SMT joints, which are more vulnerable to shear stress from cable pull and board flex. This mechanical advantage is the primary reason industrial board designers specify the SM through-hole version for cable harness connectors that are frequently mated and de-mated during field servicing.
How does the high-temperature shroud on the HTSS-133-01-SM-DV differ from a standard thermoplastic housing in elevated-temperature environments?
Standard connector thermoplastics such as PA66 (nylon) begin to soften and lose dimensional accuracy above 85°C, which can cause pin pitch distortion and contact loosening in industrial enclosures near heat sources. The HTSS-133-01-SM-DV uses a high-temperature thermoplastic rated for at least 105°C continuous service, maintaining contact pitch within 0.05mm tolerance and shroud geometry within mating clearance at elevated ambient temperatures. This prevents the shroud from deforming around the 66 pins during soldering reflow at 245°C to 260°C peak and during long-term operation in industrial environments where PCB temperatures regularly reach 90°C to 100°C.
For a 66-signal parallel bus, what cable assembly mates with the HTSS-133-01-SM-DV, and how is strain relief managed?
The HTSS-133-01-SM-DV mates with SAMTEC HTSD-133 or HTSL-133 series 66-position IDC or discrete-wire cable assemblies at the same 0.100 inch (2.54mm) pitch. SAMTEC HTSD cable assemblies include an integral strain relief clamp that grabs the outer cable jacket within 10mm of the connector body, limiting axial cable pull force transmitted to the solder joints to under 5N. For 66-conductor ribbon cables, a 66-circuit 28 AWG IDC ribbon at 2.54mm pitch is the standard match, providing approximately 1A per conductor rating with a total harness cross-section under 50mm² for routing through standard cable management channels.
When would a designer choose the HTSS-133-01-SM-DV over two separate 33-position HTSS connectors on the same PCB?
Using a single HTSS-133-01-SM-DV 66-position connector instead of two 33-position connectors reduces PCB connector count from 2 footprints to 1, saving approximately 15mm of PCB width and eliminating one mating cycle in field cable connection. A single 66-pin harness is also mechanically more stable than two separate 33-pin cables because the wider connector body distributes insertion force across 82.5mm versus two shorter 42.5mm spans, reducing board stress during mating. For signal buses that must be routed as a single cable loom through a cable management system, the single 66-position connector simplifies harness routing and labeling compared to managing two separate 33-pin cables.
