Key Features
- 50 positions in dual-row 0.100" (2.54 mm) pitch offering high-density connectivity on a compact SMT footprint
- Female socket (FM) contact style enabling mating with standard 0.100" male headers for versatile board-to-board connections
- Gold-plated contacts (K option) ensuring low contact resistance and long-term corrosion resistance in demanding environments
Applications
The TSM-125-01-FM-DH-A-K-TR is designed for backplane interconnect systems, development boards, and modular embedded computing platforms where 50 signal channels are needed across a 2.54 mm pitch dual-row layout. Its female socket contact design mates reliably with standard 0.100" male headers, supporting quick board-to-board assembly and field serviceability. This connector is commonly specified in industrial automation, instrumentation, and telecommunications equipment requiring high pin-count, space-efficient surface mount connections.

Frequently Asked Questions
What is the position count and contact arrangement of the TSM-125-01-FM-DH-A-K-TR?
The TSM-125-01-FM-DH-A-K-TR provides 50 positions arranged in 2 rows on a 0.100" (2.54 mm) pitch. This dual-row female socket surface mount terminal strip supports high-density signal routing on compact PCBs, making it suitable for embedded computing and communications applications.
Which connector series can mate with the TSM-125-01-FM-DH-A-K-TR?
The TSM-125-01-FM-DH-A-K-TR uses female socket (FM) contacts at 0.100" (2.54 mm) pitch, which mate with standard SAMTEC TSM or TSW series 0.100" male headers. This compatibility allows for direct board-to-board stacking with up to 50 signal connections, simplifying modular system design.
Why does the TSM-125-01-FM-DH-A-K-TR include gold-plated contacts and what benefit does this provide?
The K option specifies gold-plated contacts, which deliver contact resistance below 20 milliohms and resist oxidation over thousands of mating cycles. Gold plating is critical in instrumentation and telecom applications where consistent low-resistance connections must be maintained across wide temperature ranges of -55°C to +125°C.
