What are the key features of TSM-135-04-SS-DH-A-K-TR?
- 70 positions in dual-row SMT layout on 0.100" (2.54 mm) pitch providing high pin-count board interconnect
- Stainless steel (SS) hardware for enhanced mechanical retention strength and corrosion resistance
- Dual-height (DH) body enabling compatibility with multiple mating connector stack heights
- Tape-and-reel (TR) packaging for seamless integration with automated high-volume SMT assembly equipment
- RoHS compliant design with tin-based SMT termination for lead-free solder compatibility
What is TSM-135-04-SS-DH-A-K-TR used for?
The TSM-135-04-SS-DH-A-K-TR is designed for high-reliability board-to-board signal routing in industrial automation controllers, server backplanes, and communications hardware requiring 70-position dual-row SMT connectors with strong mechanical retention. The stainless steel hardware adds pull-out resistance for boards subject to vibration or repeated mate-and-unmate cycles in field-serviceable equipment. Tape-and-reel delivery supports continuous high-volume PCB manufacturing without manual feeder intervention.

Frequently Asked Questions
What role does the stainless steel (SS) hardware play in TSM-135-04-SS-DH-A-K-TR for vibration-prone industrial environments?
The stainless steel retention hardware significantly increases pull-out force on the 70-position dual-row connector body, making TSM-135-04-SS-DH-A-K-TR more resistant to mechanical shock and vibration than standard plastic-body variants. This is critical for industrial control boards and server systems where 0.100 inch pitch connectors may experience repeated mate-unmate cycles.
How does TSM-135-04-SS-DH-A-K-TR differ from TSM-135-02-SM-DH-A-K-TR in connector hardware and procurement considerations?
TSM-135-04-SS-DH-A-K-TR adds stainless steel (SS) locking hardware compared to the standard TSM-135-02 variant, increasing mechanical retention across all 70 positions. Procurement teams selecting between these MPNs should factor in the higher unit cost of SS hardware against the reduced risk of connector pull-off failures in production.
Is TSM-135-04-SS-DH-A-K-TR compatible with lead-free reflow solder profiles used in modern SMT lines?
Yes, TSM-135-04-SS-DH-A-K-TR uses tin-based SMT termination contacts that are compatible with standard lead-free reflow profiles up to 260°C peak temperature. The stainless steel hardware retains its dimensional stability across standard reflow oven thermal cycles, ensuring the 70-position body stays coplanar during soldering.
For a 70-position dual-row requirement, what stack-height flexibility does the DH designation provide?
The dual-height (DH) designation on TSM-135-04-SS-DH-A-K-TR allows it to mate with headers of two different board-to-board stack heights on the 0.100 inch (2.54 mm) pitch footprint, giving system designers flexibility to accommodate different PCB spacings in stacked module or mezzanine card designs without altering the PCB layout.
