Frequently Asked Questions
What is the contact pitch and total pin count of the TFM-140-03-S-D-RA, and how does this affect PCB routing density?
The TFM-140-03-S-D-RA features a 0.050" (1.27 mm) pitch with 80 total contacts arranged in a dual-row configuration of 40 pins per row. This fine pitch allows high-density signal routing on compact PCBs, making it suitable for embedded control boards where space is limited and signal count is high.
What is the right-angle orientation of TFM-140-03-S-D-RA suitable for in panel-mount or edge-access connector applications?
The right-angle (RA) configuration of the TFM-140-03-S-D-RA orients the 80 contacts at 90 degrees to the PCB surface, enabling edge-access connections in panel-mount enclosures. This is ideal for industrial modules and embedded systems requiring front-panel or side-wall connector access at 1.27 mm pitch without vertical stacking.
How does TFM-140-03-S-D-RA compare to straight-through versions of the TFM series in terms of board-to-board stacking?
Unlike straight-mount TFM variants that support vertical board-to-board stacking with stack heights as low as 2 mm, the TFM-140-03-S-D-RA's right-angle orientation directs all 80 contacts horizontally. This makes it a better fit for cable-to-board or panel-to-board connections at 1.27 mm pitch rather than direct board-to-board mating.
What current capacity does each contact in the TFM-140-03-S-D-RA support for mixed power and signal designs?
Each contact in the TFM-140-03-S-D-RA is rated at approximately 1 A, with contact resistance typically under 20 mΩ. In a mixed power-and-signal design with 80 contacts, designers can allocate dedicated power rails while keeping signal contacts isolated, supporting logic levels from 1.8 V to 5 V across industrial modules.
