What are the key features of TFM-146-12-H-D-A-P-TR?
- High-reliability Tiger Eye dual-beam contacts at 0.050 inch pitch delivering low contact resistance across thousands of mating cycles
- 92 total dual-row contacts (-D) with -H stack height option for optimized board-to-board mezzanine spacing in embedded systems
- Tape-and-reel (-TR) and polarized (-A-P) configuration preventing misalignment errors during automated high-volume PCB assembly
What is TFM-146-12-H-D-A-P-TR used for?
The TFM-146-12-H-D-A-P-TR is designed for high-density board-to-board mezzanine interconnects in ruggedized embedded computing, defense electronics, and industrial automation platforms. With 92 contacts at 0.050 inch pitch in the -H stack height, it supports dense signal and power routing between processor boards and expansion daughtercards in compact chassis designs. The Tiger Eye contact system and polarization keying ensure reliable, error-free mating in production environments with high assembly throughput requirements.

Frequently Asked Questions
What contact count and pitch does the TFM-146-12-H-D-A-P-TR provide for mezzanine board interconnects?
The TFM-146-12-H-D-A-P-TR provides 92 total contacts in a dual-row configuration at 0.050 inch (1.27 mm) pitch. This high contact density supports extensive signal and power routing between stacked boards in embedded computing and industrial platforms, enabling complex system integration while keeping the overall connector footprint compact enough for space-constrained mezzanine card designs.
How does polarization keying (-A-P) in the TFM-146-12-H-D-A-P-TR prevent assembly errors?
The -A-P polarization feature incorporates a physical key on the connector body that prevents insertion in an incorrect orientation, making it impossible to mate the 92-position dual-row connector backwards during assembly. This is critical in high-volume automated SMT production where a reversed 0.050 inch pitch connector could damage 92 contact pairs, cause board failures, or require costly rework in aerospace and defense electronics manufacturing environments.
What stack height does the -H option provide, and how does it compare to low-profile alternatives in chassis-constrained designs?
The -H stack height in the TFM-146-12-H-D-A-P-TR designates a taller mated board separation, typically around 12 mm, compared to -L low-profile or -S standard options. This additional clearance accommodates components mounted on either mating board that require more vertical space, such as through-hole capacitors over 10 mm in height, transformers, or heat sinks on processor daughtercards in enclosed rack-mount or ruggedized chassis assemblies.
