Key Features
- 70-position dual-row .100" (2.54 mm) pitch surface mount terminal strip with stainless steel shell for robust EMI shielding
- Gold-plated contacts rated at 3A per pin provide low-resistance connections suitable for both signal and light power distribution
- Tape-and-reel (TR) packaging supports high-volume automated pick-and-place SMT assembly processes
Applications
The TSM-135-01-SS-DH-A-K-TR is targeted at industrial control systems, ruggedized computing boards, and high-frequency signal processing equipment where both connector density and EMI shielding are critical. Its stainless steel shell provides mechanical protection and shielding continuity across the 70-position dual-row interface. The .100" pitch dual-row layout is compatible with standard DIP and card-edge header footprints used in industrial backplanes.

Frequently Asked Questions
How does the stainless steel shell of TSM-135-01-SS-DH-A-K-TR improve performance compared to standard TSM variants without a shell?
The stainless steel (SS) shell on the TSM-135-01-SS-DH-A-K-TR provides a grounded enclosure that reduces electromagnetic interference ingress and egress across the 70-position contact array. In high-frequency environments above 100 MHz, the shell can attenuate radiated noise by 10 dB or more compared to unshielded connectors of similar pin count, improving signal integrity in dense PCB assemblies.
What is the total current capacity of the TSM-135-01-SS-DH-A-K-TR when all 70 contacts carry current simultaneously?
With each of the 70 contacts rated at 3A, the TSM-135-01-SS-DH-A-K-TR can theoretically carry up to 210A in aggregate when all pins are used for power distribution. In practice, designers derate to 70–80% of rated current per contact, yielding a practical capacity of approximately 147A to 168A for thermally stable continuous operation.
For a ruggedized industrial backplane, what mounting and assembly benefits does the TSM-135-01-SS-DH-A-K-TR offer?
The TSM-135-01-SS-DH-A-K-TR is surface mount compatible with tape-and-reel delivery for automated SMT placement, achieving accurate 0.1 mm positioning tolerances on a standard .100" (2.54 mm) grid. The stainless steel shell mechanically locks to the PCB pad, increasing pull-out resistance above 50 N to withstand vibration in industrial rack-mount or vehicle-mounted systems.
How does the dual-row DH configuration of TSM-135-01-SS-DH-A-K-TR affect PCB routing compared to a single-row variant?
The dual-row DH layout places 35 contacts per row, reducing the total connector body length to approximately 88.9 mm (35 × 2.54 mm) versus 177.8 mm for a single-row 70-pin part. This halved footprint length frees PCB routing channels on both sides of the connector, simplifying escape routing for dense 6-layer or 8-layer backplane designs.
