Key Features
- 70-position dual-row surface mount strip with 0.100" (2.54mm) pitch for maximum signal density in a compact footprint
- Dual-height (DH) body provides additional board clearance for stacked connector assemblies or taller adjacent components
- Tape-and-reel (TR) packaging with key polarization (K) option prevents incorrect mating during automated and manual assembly
Applications
The TSM-135-03-H-DH-A-K-TR is used in FPGA daughter boards, processor modules, and high-channel-count data acquisition systems where 70 signals must traverse a board edge or stacking interface on a 0.100" grid. The key polarization feature also makes it suitable for manufacturing environments where accidental reversed connector insertion must be prevented, such as in military, industrial automation, or medical device assembly.

Frequently Asked Questions
What is the position count and row configuration of TSM-135-03-H-DH-A-K-TR?
The TSM-135-03-H-DH-A-K-TR has 70 positions arranged in a dual-row layout on 0.100" (2.54mm) pitch, providing 35 contacts per row. This dual-row 70-position configuration is suited for FPGA expansion headers, SoM carrier boards, or any interface bus requiring more than 60 signal pins in a standard 2.54mm grid connector.
How does the key polarization (K) feature on TSM-135-03-H-DH-A-K-TR prevent connector assembly errors?
The K suffix on TSM-135-03-H-DH-A-K-TR indicates a polarization key that physically blocks incorrect mating orientation. In manufacturing lines or field installation scenarios where a 70-position connector could otherwise be inserted reversed, the key pin blocks a keyed position in the mating receptor, preventing all 70 contacts from making incorrect electrical connections and protecting downstream circuits.
When should TSM-135-03-H-DH-A-K-TR be selected over the 66-position TSM-133 for a new board design?
TSM-135-03-H-DH-A-K-TR with 70 positions is the appropriate choice when a design needs more than 66 signal pins in a single connector, such as when routing a 64-bit data bus plus control, power, and ground signals requiring at least 68–70 contacts. The additional 4 positions compared to TSM-133 also allow designers to include spare or ground pins within the same 0.100" pitch footprint without adding a second connector.
What tape-and-reel packaging details does TSM-135-03-H-DH-A-K-TR offer for SMT production?
The TR suffix confirms TSM-135-03-H-DH-A-K-TR is packaged in carrier tape and reel, compatible with standard automated pick-and-place machines operating on 0.100" component pitch grids. This packaging format reduces handling time, supports reel-to-feeder loading for SMT lines, and maintains component orientation consistency for all 70 contacts during high-volume PCB assembly.
