Key Features
- 66-position dual-row 0.100" pitch SMT layout with 33 contacts per row for dense signal and power routing on embedded interface boards
- Keyed (K) mating option prevents incorrect polarity insertion, critical for protecting circuits operating at 3.3 V, 5 V, or mixed-voltage rails
- Tape-and-reel (TR) packaging supports automated SMT pick-and-place lines, minimizing per-unit assembly time in high-volume production
Applications
The TSM-133-04-S-DH-A-K-TR terminal strip is suited for industrial I/O expansion modules, FPGA evaluation boards, and data acquisition cards that require a 66-position dual-row connector with polarized keying to prevent mis-mating. Its 0.100" pitch layout accommodates simultaneous digital, analog, and power signals across 66 contacts, simplifying cable harness design for multi-signal interface applications. Engineers in industrial automation and embedded computing routinely specify this part for motherboard-to-daughter-board connections where SMT assembly efficiency and secure connector orientation are equally important.

Frequently Asked Questions
How does the 66-position count of TSM-133-04-S-DH-A-K-TR compare to standard 64-position dual-row connectors?
TSM-133-04-S-DH-A-K-TR provides 66 positions (33 per row at 0.100" pitch) versus common 64-position alternatives, giving designers 2 additional contacts to assign as extra ground returns or spare I/O lines without increasing the connector's physical row count or changing the 0.100" pitch standard footprint.
What keying benefit does the 'K' option provide on a 66-position connector like TSM-133-04-S-DH-A-K-TR?
The K keying option includes a physical polarizing key that blocks insertion in the wrong orientation, preventing the reverse-polarity mating that could damage 66-position dual-row bus interfaces operating at 5 V or 3.3 V logic levels — an important safeguard on high-density connectors where visual orientation cues are small.
For an industrial I/O module design, what is the signal capacity advantage of using TSM-133-04-S-DH-A-K-TR over two separate 33-position single-row connectors?
A single TSM-133-04-S-DH-A-K-TR consolidates all 66 positions into one dual-row footprint measuring approximately 82.5 mm in row length, whereas two separate 33-position single-row connectors would require twice the board real estate and two separate mating operations, increasing both PCB area consumption and assembly time.
