What are the key features of TFM-146-13-SM-D?
- 92 positions in a dual-row 0.050" pitch layout delivers ultra-high density for edge-card and board-to-board stacking
- Tiger Eye contact technology applies consistent normal force across all 92 pins for reliable mating retention and low contact resistance
- Straddle-mount (SM) termination style allows the connector to mount on the PCB edge for space-efficient card-edge interfaces
- High-reliability design rated for thousands of mating cycles in demanding industrial, aerospace, and communications applications
What is TFM-146-13-SM-D used for?
The TFM-146-13-SM-D is designed for high-reliability board-to-board and card-edge interconnect applications in FPGA development boards, high-speed data acquisition systems, and communications backplanes requiring 92 connections at 0.050" pitch. Its straddle-mount termination places the connector on the PCB edge, enabling compact stacking configurations in modular embedded computing and server blade designs. The Tiger Eye contact design ensures consistent mating force across all 92 positions, supporting reliable operation in aerospace avionics, military electronics, and high-cycle industrial test equipment.

Frequently Asked Questions
What does straddle-mount (SM) termination mean for the TFM-146-13-SM-D, and how does it differ from surface mount?
Straddle-mount termination means the TFM-146-13-SM-D connector body straddles the PCB edge with contacts on both sides of the board, mechanically clamping onto 0.050" pitch pads rather than sitting on a single PCB surface. This provides both 92-pin electrical contact and strong mechanical retention without requiring a separate housing, unlike a standard surface mount connector that attaches to only one PCB face.
How many positions does the TFM-146-13-SM-D provide, and what SAMTEC socket series does it mate with?
The TFM-146-13-SM-D provides 92 total positions in a dual-row 0.050" pitch configuration (2 rows of 46 pins each). It mates with SAMTEC SFM series female socket strips at the same 0.050" pitch, and the Tiger Eye contacts on both connectors ensure a consistent normal force across all 92 mating pairs for high-reliability signal integrity.
Why choose the TFM Tiger Eye series over standard TFC connectors for a high-cycle test fixture at 0.050" pitch?
The TFM Tiger Eye series is rated for significantly more mating cycles than the cost-optimized TFC series, typically exceeding 500 mating cycles with consistent contact force across 92 positions at 0.050" pitch. For test fixtures that mate and unmate boards hundreds of times, the TFM series' beryllium copper contacts and Tiger Eye geometry maintain stable contact resistance below 20 mΩ, whereas TFC contacts may degrade more rapidly under repeated mechanical stress.
