What are the key features of TSM-123-02-SM-DH-A-K-TR?
- 46-position dual-row layout on standard 0.100 inch (2.54 mm) pitch provides 23 contacts per row for broad mating connector compatibility with SAMTEC SFM and equivalent socket families
- Surface-mount tape-and-reel packaging enables automated SMT pick-and-place and reflow soldering for high-volume industrial and telecom PCB assembly
- SAMTEC TSM series high-reliability construction supports repeated mating cycles with consistent low contact resistance across the 46-pin interface
What is TSM-123-02-SM-DH-A-K-TR used for?
TSM-123-02-SM-DH-A-K-TR is designed for high-density board-to-board and daughter-card signal interconnects in embedded computing, industrial automation, and telecommunications equipment requiring 46 parallel signal lines. Its 0.100" pitch dual-row configuration mates with SAMTEC SFM-123 or equivalent socket strips, supporting reliable data bus and power routing between mezzanine modules and main backplanes. The tape-and-reel format integrates into automated SMT assembly lines for consistent placement of the high-pin-count connector in production environments.

Frequently Asked Questions
How many contacts and rows does TSM-123-02-SM-DH-A-K-TR have, and what pitch does it use?
TSM-123-02-SM-DH-A-K-TR has 46 contacts in a dual-row configuration with 23 contacts per row on a standard 0.100 inch (2.54 mm) pitch. This pin count and pitch make it compatible with a broad range of SAMTEC SFM series socket strips and third-party 2.54 mm pitch mating connectors used in board-to-board and daughter-card interconnect applications.
Can TSM-123-02-SM-DH-A-K-TR be assembled using automated SMT pick-and-place equipment?
Yes, TSM-123-02-SM-DH-A-K-TR is a surface-mount connector supplied in tape-and-reel (TR) format, fully compatible with automated pick-and-place equipment. It supports standard SMT reflow soldering, enabling consistent placement of the 46-position connector body at 2.54 mm pitch across high-volume PCB production runs in industrial and telecom manufacturing.
For a 46-pin data bus interface between a carrier board and a mezzanine module, what socket mates with TSM-123-02-SM-DH-A-K-TR?
TSM-123-02-SM-DH-A-K-TR is designed to mate with SAMTEC SFM-123 series dual-row socket strips on a 0.100 inch (2.54 mm) pitch. The 46-position SFM-123 socket accepts all 46 contacts and provides a secure board-to-board stack height that can be specified with different stacking heights to accommodate mezzanine module clearance requirements.
When is a 46-position SMT terminal strip preferred over a through-hole equivalent for an industrial backplane design?
A 46-position SMT terminal strip like TSM-123-02-SM-DH-A-K-TR is preferred when the backplane PCB is assembled entirely by reflow soldering, eliminating the need for through-hole drilling and wave solder processes. The SMT footprint also reduces connector height above the PCB by several millimeters compared to through-hole alternatives, aiding vertical clearance in compact chassis with standard 1U or 2U rack heights accommodating 46-pin signal interfaces.
