Key Features
- 70-position dual-row (2×35) SMT terminal strip at 0.100" (2.54 mm) pitch for high-density backplane and module interfaces
- 4.0 mm through-hole tail (TL) combined with kinked tail (K) option delivering maximum solder joint pull strength for vibration-prone applications
- Tape-and-reel (TR) packaging enabling automated pick-and-place placement in high-volume SMT production lines
- Gold-plated contacts available for low-resistance mating in 70-position signal-intensive interconnect designs
Applications
The TSM-135-02-TL-DH-A-K-TR serves high-density PCB interconnect needs in backplane assemblies, embedded computing modules, and industrial control cards where 70 dual-row positions at 0.100" pitch are required. The kinked through-hole tail construction makes it especially suitable for rugged environments subject to mechanical shock or vibration, such as automotive test equipment racks, server expansion boards, and defense electronics subassemblies.

Frequently Asked Questions
What is the pin configuration and pitch of the TSM-135-02-TL-DH-A-K-TR, and how does it compare to smaller TSM variants?
The TSM-135-02-TL-DH-A-K-TR provides 70 positions in a 2×35 dual-row layout at a 0.100" (2.54 mm) pitch, spanning approximately 88.9 mm along the row axis. This makes it one of the larger TSM series strips, offering 14 more positions than the TSM-129 variant while using the identical 0.100" mating system.
How does the kinked tail (K) option improve mechanical retention compared to a standard straight tail?
The kinked tail creates a press-fit retention feature that grips the through-hole barrel before soldering, holding the 70-position connector in place during reflow and preventing tombstoning. After soldering, the kinked geometry increases solder joint peel strength by up to 30% compared to a straight tail, benefiting vibration-rated assemblies at shock levels exceeding 10 G.
Which backplane or module applications are best matched to this 70-position dual-row terminal strip?
A 70-position (2×35) strip at 0.100" pitch suits VME, cPCI, and custom backplane card-edge interfaces carrying 60 to 70 signal lines alongside dedicated power and ground contacts. It is also used on FPGAs and DSP evaluation boards where 70 I/O pins must break out to standard 0.100" header footprints for daughtercard expansion.
Does the tape-and-reel packaging support automated placement, and what reflow temperature is supported?
Yes. The TR (tape-and-reel) suffix confirms EIA-481 compliant packaging for automated pick-and-place at standard SMT feeder stations. The TSM-135-02-TL-DH-A-K-TR supports Pb-free reflow soldering with a peak temperature of 260°C per J-STD-020, compatible with modern lead-free production lines processing boards at standard 30-second dwell times at peak.
