What are the key features of TSM-134-04-L-DH-A-K-TR?
- 68-position 0.100" pitch double-row SMT terminal strip with keyed polarization to prevent mis-mating
- Double-height (DH) body provides over 8.5 mm clearance above PCB for daughter-card or cable connections
- Tape-and-reel (TR) format with gold-plated contacts supports high-reliability automated SMT production
What is TSM-134-04-L-DH-A-K-TR used for?
The TSM-134-04-L-DH-A-K-TR is used in high-density computing modules, industrial backplane assemblies, and embedded control systems requiring 68 surface-mount contacts at 0.100" pitch with reliable keyed polarization. Its double-row double-height layout maximizes contact density while providing clearance for daughter-card mating above the PCB. Tape-and-reel packaging ensures efficient pick-and-place integration for volume production environments.

Frequently Asked Questions
What does the keyed (K) option on TSM-134-04-L-DH-A-K-TR provide in a 68-position board connector?
The keyed (K) option on TSM-134-04-L-DH-A-K-TR adds a physical polarization feature that prevents incorrect mating orientation across the 68-position 0.100 inch pitch double-row terminal strip. This mechanical key ensures the mating connector inserts in only one direction, eliminating reverse-polarity connection errors in industrial control boards, computing backplanes, and mixed-signal I/O modules where mis-mating could damage circuits or corrupt data.
How does a 68-position double-row layout at 0.100" pitch compare to a single-row 68-position connector for PCB area?
A double-row layout on the TSM-134-04-L-DH-A-K-TR arranges 68 contacts across 2 rows of 34 positions each at 0.100 inch pitch, reducing the connector length to approximately 1.7 inches versus 3.4 inches for an equivalent single-row 68-position connector at the same pitch. This nearly 50% reduction in board edge length is critical for dense PCB designs in compact industrial controllers, computing modules, and rack-mount backplane systems.
In which production scenario does TSM-134-04-L-DH-A-K-TR tape-and-reel packaging yield the greatest cost saving?
Tape-and-reel packaging on TSM-134-04-L-DH-A-K-TR yields the greatest cost saving in automated SMT production runs of 1000 units or more, where pick-and-place throughput for 68-pin connectors typically reaches 300 to 500 placements per hour versus fewer than 50 placements per hour with manual insertion. Eliminating manual placement reduces labor cost per board by approximately 15 to 30 seconds for each 68-position connector installed.
What mating connector series is compatible with TSM-134-04-L-DH-A-K-TR for a keyed board-to-board interface?
TSM-134-04-L-DH-A-K-TR mates with SAMTEC SSW or TSW series receptacle strips at 0.100 inch pitch that include a compatible keying feature, supporting board-to-board mating heights from 8.5 mm to 15 mm above the PCB surface. Selecting the keyed mating receptacle ensures 68-position alignment on the first insertion, reducing assembly errors in high-mix industrial production where multiple connector variants of similar size share the same line.
