Key Features
- 70-position dual-row shrouded terminal strip on 0.100 inch (2.54 mm) pitch for very high-density cable-to-board signal interconnection
- High-temperature housing rated for continuous operation up to approximately 125°C, preventing warpage near power components or in hot enclosures
- Through-hole mount (TM) termination style provides maximum mechanical retention strength on PCBs subject to cable pull-out forces
- Dual-voltage (DV) variant enables split-supply or mixed-signal wiring harnesses to connect through a single polarized 70-pin interface
- Shrouded polarized housing eliminates mis-mating risk across all 70 contacts, critical for high-count cable harnesses in field-serviceable systems
Applications
The HTSS-135-01-TM-DV is well suited for high-density cable-to-board wiring in industrial programmable logic controllers, defense avionics backplanes, and server rack management cards where 70 or more signals must be reliably interconnected through a single polarized connector. Its through-hole mount termination provides superior pull-out strength for cable harnesses in vibrating environments such as motor control panels and vehicle electronics. The high-temperature housing and 0.100 inch pitch compatibility with IDC ribbon cables make it a practical choice for both prototype development and volume production of telecom and embedded computing systems.

Frequently Asked Questions
How does through-hole mounting of HTSS-135-01-TM-DV improve mechanical retention compared to surface-mount alternatives in vibrating environments?
Through-hole mount (TM) termination anchors each of the 70 pins into drilled PCB holes and solders them on the opposite side, providing mechanical pull-out resistance of several kilograms per pin versus less than 1 kg for typical SMT solder joints under lateral cable tension. In vibrating environments such as vehicle electronics or motor drive panels, through-hole mounting reduces the risk of connector solder joint cracking under cyclic stress loads above 10 G vibration amplitude, making it the preferred termination for cable-mate connectors subjected to repeated plug-and-pull operations.
For a 70-channel PLC I/O wiring harness, what PCB span does HTSS-135-01-TM-DV require and how does it affect board layout?
With 35 positions per row at 0.100 inch (2.54 mm) pitch in a dual-row arrangement, the HTSS-135-01-TM-DV spans approximately 3.5 inches (88.9 mm) in length, requiring a keepout zone of 88.9 mm plus at least 5 mm on each end for shroud walls and cable clearance. PCB layout must allocate this length on one board edge and route 70 through-hole vias on a 0.100 inch grid, typically requiring 3 or more routing layers to fan out all signals within the connector footprint.
Which cable assemblies are compatible with HTSS-135-01-TM-DV for rapid prototype harness wiring?
HTSS-135-01-TM-DV mates with standard 0.100 inch pitch dual-row IDC socket housings and 70-conductor flat ribbon cables, rated at 300 V and 1 A per conductor for low-current signal and auxiliary power wiring. Mass-terminated IDC assemblies can be crimped to 70-conductor ribbon cables using standard IDC tooling, enabling rapid harness prototyping without custom tooling. Samtec and other connector vendors also offer discrete-wire housing options for custom harness lengths.
At what ambient temperature does HTSS-135-01-TM-DV begin to risk housing deformation, and what applications push it to that limit?
The high-temperature housing of HTSS-135-01-TM-DV is rated for continuous operation at approximately 125°C, which is the threshold at which most standard nylon or PBT housings rated to 85°C begin to warp and lose pin registration. Applications that approach this limit include servo drive controller PCBs mounted in sealed metal enclosures where internal temperatures reach 100°C to 120°C, and aerospace avionics bays with limited forced-air cooling where ambient temperatures can exceed 85°C during maximum power operation.
