Key Features
- 68-position dual-row surface mount layout at 0.100" pitch providing 34 positions per row in a single low-profile connector footprint
- Keying (K option) prevents incorrect mating orientation, reducing assembly errors in 68-position high-density interconnect systems
- Tape-and-reel (TR) packaging enables automated SMT pick-and-place assembly for cost-effective high-volume production runs
Applications
The TSM-134-03-SM-DH-A-K-TR terminal strip is ideally suited for industrial control modules, server expansion cards, and embedded computing backplanes that require a 68-position surface mount interface with keyed mating prevention. Its dual-row 0.100" pitch layout supports simultaneous routing of analog signals, digital I/O, power rails, and ground connections across a compact board edge or mid-board connector region. The tape-and-reel format and SMT footprint make this connector a preferred choice for automated assembly lines producing FPGA evaluation boards, motor drive controller cards, and data acquisition modules.

Frequently Asked Questions
How many contact positions does the TSM-134-03-SM-DH-A-K-TR offer and how are they distributed?
The TSM-134-03-SM-DH-A-K-TR provides 68 positions arranged in a dual-row format at 0.100" (2.54 mm) pitch, with 34 contacts per row, allowing designers to assign power, ground, and signal lines across both rows to minimize PCB routing complexity.
What does the 'K' suffix on TSM-134-03-SM-DH-A-K-TR indicate about connector assembly?
The 'K' suffix denotes a polarizing key feature that physically prevents incorrect mating orientation, reducing mis-insertion risk during board assembly and field servicing — critical on 68-position connectors where reversing polarity could damage sensitive circuits powered at 3.3 V or 5 V.
Can TSM-134-03-SM-DH-A-K-TR be used in high-volume automated SMT lines, and what packaging does it ship in?
Yes, the TR suffix indicates tape-and-reel packaging compatible with standard SMT pick-and-place feeders, supporting automated assembly at production rates common in consumer electronics and industrial control manufacturing — typically thousands of placements per hour without manual intervention.
