What are the key features of TSM-134-01-LM-DH-P-TR?
- 68-position configuration on a standard 0.100" (2.54 mm) pitch providing broad compatibility with SAMTEC mating socket strips
- Dual-height (DH) and polarized (P) design preventing mis-mating across a 68-pin interface in field-serviceable assemblies
- Low-profile SMT tape-and-reel packaging enabling automated pick-and-place assembly without through-hole drilling
What is TSM-134-01-LM-DH-P-TR used for?
The TSM-134-01-LM-DH-P-TR is designed for embedded computing expansion boards, industrial PLC backplanes, and test-and-measurement modular assemblies requiring 68 contacts at 0.100" pitch. Its dual-height polarized feature prevents reversed insertion in high-contact-count connectors where a single mis-seating could damage 3.3 V or 5 V digital bus lines. The surface mount low-profile construction and tape-and-reel packaging reduce manufacturing cost in volume SMT production runs.

Frequently Asked Questions
How many pins does the TSM-134-01-LM-DH-P-TR carry and what is the connector pitch?
The TSM-134-01-LM-DH-P-TR is a 68-position terminal strip on a 0.100" (2.54 mm) pitch. This standard pitch ensures direct compatibility with a wide range of SAMTEC and third-party socket strips, ribbon cable IDC headers, and test fixture sockets that use the 0.100" grid as their baseline.
How does the low-profile (LM) male pin height of the TSM-134-01-LM-DH-P-TR compare to a standard-height pin and what clearance does it require?
The LM (low mating height) designation on the TSM-134-01-LM-DH-P-TR means the pin extends a shorter distance above the PCB surface than standard-height variants, typically 2 mm to 3 mm versus 5 mm or more. This reduced pin height demands a corresponding low-profile mating socket and results in a board-to-board stack height under 6 mm, which is beneficial for compact embedded modules and slim panel-mount industrial controllers with limited chassis depth.
In a 68-pin bus connection, how does the polarized (P) feature of the TSM-134-01-LM-DH-P-TR reduce assembly errors compared to a non-polarized header?
For a 68-pin 0.100" pitch connector, the polarized (P) feature introduces a mechanical asymmetry, such as a missing pin or keyed housing slot, that blocks 180° reverse mating. Without polarization, a technician assembling a backplane with 68 contacts could easily seat the mating socket inverted, applying 5 V or 12 V logic signals to ground pins and potentially damaging the connected ICs. The polarization feature makes this error physically impossible, reducing rework and field-failure rates in production and service environments.
