What are the key features of TSM-134-04-TL-DH-A-P-TR?
- 68-position dual-row (DH) configuration on 2.54 mm (0.100 inch) pitch delivers high pin-count connectivity within a single compact surface mount footprint
- Anti-wicking (A) termination option prevents solder from wicking up contact tails during reflow, ensuring clean solder joints across all 68 positions in automated assembly
- Low-profile (TL) body with polarization peg (P) minimizes stack height and prevents rotational mis-placement in high-density SMT PCB designs
What is TSM-134-04-TL-DH-A-P-TR used for?
The TSM-134-04-TL-DH-A-P-TR is suited for high pin-count board-to-board and board-to-wire interfaces in embedded computing, FPGA development boards, and industrial automation controllers where 68-pin connectivity at 2.54 mm pitch is needed. Its anti-wicking termination and low-profile design ensure manufacturing quality and reduced height in high-density PCB assemblies for data acquisition systems, motor control drives, and communication infrastructure equipment. The tape-and-reel format supports efficient automated pick-and-place production for high-volume electronics manufacturing.

Frequently Asked Questions
What does the anti-wicking (A) termination option on the TSM-134-04-TL-DH-A-P-TR do during reflow soldering?
The anti-wicking (A) termination option applies a solder-resist treatment to the contact tails above the soldering zone, preventing molten solder from wicking upward along the 68 contact pins by capillary action during SMT reflow. Solder wicking into the contact body can immobilize spring contacts and degrade mating force, so the anti-wicking feature ensures reliable solder joints at the pad interface without compromising contact elasticity across all 68 positions.
How does the 68-position count of the TSM-134-04-TL-DH-A-P-TR compare to lower pin-count TSM connectors for high-density designs?
With 68 positions arranged in a dual-row layout at 2.54 mm (0.100 inch) pitch, the TSM-134-04-TL-DH-A-P-TR provides 34 pins per row, making it one of the highest pin-count options in the TSM series. Compared to an 18-position TSM-109 or a 30-position TSM-115, this 68-pin connector consolidates what would otherwise require multiple smaller connectors into a single footprint, simplifying PCB routing for complex multi-signal interfaces in FPGA development boards and embedded computing modules.
For a compact PCB enclosure with strict height limits, how does the low-profile (TL) variant of the TSM-134-04-TL-DH-A-P-TR help?
The TL (low-profile) designation on the TSM-134-04-TL-DH-A-P-TR indicates a reduced above-board connector body height compared to standard TSM series variants. This lowers the total PCB assembly height, making it compatible with slim enclosure designs and closely spaced board stacks where standard-height 68-pin connectors would exceed the available clearance. For reference, SAMTEC's low-profile TSM variants typically reduce mated stack height by 1 mm or more compared to their standard counterparts.
How does tape-and-reel (TR) packaging of the TSM-134-04-TL-DH-A-P-TR benefit high-volume PCB production?
Tape-and-reel (TR) packaging feeds individual connectors into compatible pick-and-place machines automatically, enabling consistent component placement across all 68 positions without manual handling. For high-volume production runs, tape-and-reel reduces placement cycle time, minimizes handling damage to fine-pitch contacts, and supports continuous automated assembly without stopping to manually load connectors. This is especially important for a 68-pin component where manual placement accuracy would be difficult to maintain across thousands of units.
