What are the key features of TSM-120-03-L-DH-A-K-TR?
- 40-position dual-row surface mount terminal strip with 0.100" (2.54 mm) pitch for standard-density PCB board-to-board and wire-to-board connections
- Tape-and-reel (TR) packaging for compatibility with automated pick-and-place equipment in high-volume SMT PCB assembly lines
- Dual horizontal (DH) contact orientation providing low-profile SMT termination suitable for compact PCB designs with height constraints
What is TSM-120-03-L-DH-A-K-TR used for?
The TSM-120-03-L-DH-A-K-TR terminal strip is used in industrial control panels, embedded computing systems, and test and measurement equipment where 40 signal connections are needed across a 0.100" pitch SMT interface. Its dual-row layout concentrates 40 contacts in half the linear board space of a single-row equivalent, benefiting PLC I/O modules and sensor interface boards with tight edge dimensions. Tape-and-reel supply makes it an efficient choice for automated high-volume production of telecommunications and automation equipment.

Frequently Asked Questions
What row configuration and pitch does TSM-120-03-L-DH-A-K-TR use to achieve 40 positions in a compact SMT footprint?
The TSM-120-03-L-DH-A-K-TR features 40 positions in a dual-row (2x20) layout with 0.100" (2.54 mm) pitch. This dual-row design reduces the connector's linear PCB length to approximately 50.8 mm (20 positions at 2.54 mm each), compared to 101.6 mm for a single-row 40-pin strip, enabling compact board designs in industrial automation, data acquisition, and embedded processing applications.
How does the horizontal (DH) contact orientation of TSM-120-03-L-DH-A-K-TR affect PCB height and mating connector selection?
The dual horizontal (DH) orientation means the contacts exit the connector body horizontally relative to the PCB surface, providing a lower overall mated height compared to vertical configurations. This is beneficial in enclosures with less than 10 mm of vertical clearance above the PCB, such as slim rack-mount industrial controllers and panel-mount modules where height-profile is constrained to less than 8 mm above the PCB surface.
For a PLC I/O expansion module requiring 40 connections, when should TSM-120-03-L-DH-A-K-TR be preferred over screw-terminal connectors?
TSM-120-03-L-DH-A-K-TR with its 0.100" (2.54 mm) pitch SMT design is preferable to screw-terminal blocks when the PLC I/O module requires automated assembly, board-to-board rather than wire-to-board connections, or a lower PCB footprint than the typical 5.08 mm or 3.81 mm pitch of screw terminals. For 40-channel interfaces where module weight, size, and production volume above 500 units per run are constraints, the SMT terminal strip enables faster assembly at lower per-unit cost.
