What are the key features of TSM-125-02-TM-DH-A-K-TR?
- 50-position dual-row SMT terminal strip at 0.100" (2.54 mm) pitch providing 50 connections on the industry-standard grid spacing compatible with a wide range of mating connectors and cable assemblies
- Keyed (-K) housing prevents incorrect mating orientation across all 50 positions, eliminating reverse-insertion damage in field-assembled or frequently connected systems
- Tape-and-reel (-TR) packaging enables automated high-speed SMT pick-and-place assembly at production throughput rates, reducing per-unit placement cost versus tube or tray packaging
What is TSM-125-02-TM-DH-A-K-TR used for?
The TSM-125-02-TM-DH-A-K-TR is used in backplane and mid-plane interconnects, development boards, and industrial control panel wiring where 50 signals must be reliably connected via the standard 0.100" pitch grid. Its keyed dual-row configuration is common in embedded computing expansion interfaces, PLC I/O modules, and test fixture wiring harnesses where connector polarity must be enforced mechanically. The SMT format with tape-and-reel packaging makes it suitable for volume production of consumer electronics and network hardware where automated assembly is required.

Frequently Asked Questions
How does the keyed housing of the TSM-125-02-TM-DH-A-K-TR protect a 50-position interface from incorrect mating?
The -K key on the TSM-125-02-TM-DH-A-K-TR adds a mechanical polarization feature to the 50-position dual-row housing that physically blocks insertion in any orientation other than the correct pin-1 alignment. This prevents reverse-polarity mating that could short supply rails, damage signal drivers, or destroy components connected across all 50 pins in power-on field-service or laboratory scenarios.
For a 50-signal backplane interface at 0.100" pitch, how does the TSM-125-02-TM-DH-A-K-TR compare to a through-hole version?
The surface-mount TSM-125-02-TM-DH-A-K-TR eliminates the need to drill 50 pairs of through-holes (100 holes at 0.100" grid), saving PCB fabrication cost and allowing signal routing on inner layers where the via barrels would otherwise block traces. SMT placement also integrates with the standard reflow solder process, removing the separate wave-solder or hand-solder step that through-hole connectors add to the production workflow.
What mating connectors are compatible with the TSM-125-02-TM-DH-A-K-TR for cable-to-board applications?
The TSM-125-02-TM-DH-A-K-TR is a 0.100" (2.54 mm) pitch dual-row terminal strip that mates with standard IDC ribbon cable connectors and discrete wire housing assemblies in the same 2×25 pin format. Compatible mating options include SAMTEC's FTS or FTSH series female housings, as well as generic 50-pin IDC cable connectors, allowing the same board connector to accept multiple cable assembly styles in prototyping and production environments.
