What are the key features of TFM-120-01-S-D-A-P-TR?
- 20-position single-row dual-beam Tiger Eye terminal strip with 0.050" (1.27 mm) pitch for high-reliability signal board-to-board connections in space-constrained SMT designs
- Dual-beam (D) contact design provides two independent contact points per pin, doubling redundancy and ensuring stable signal path even with minor co-planarity variations
- Tape-and-reel (TR) packaging with anti-vibration (-A) feature enables precise automated pick-and-place at ±0.05 mm accuracy on fine-pitch 0.050" SMT pads
What is TFM-120-01-S-D-A-P-TR used for?
The TFM-120-01-S-D-A-P-TR is designed for high-reliability single-row signal interconnects in instrumentation modules, compact embedded processors, and sensor fusion boards that require 20-pin 0.050" pitch connections with dual-beam contact redundancy. Its tape-and-reel format supports automated assembly in high-volume consumer, medical, and industrial electronics manufacturing. The dual-beam contact design is particularly valuable in safety-critical applications such as medical diagnostic equipment and avionics where single-point contact failure cannot be tolerated.

Frequently Asked Questions
What does the dual-beam contact design in TFM-120-01-S-D-A-P-TR mean for signal reliability compared to single-beam alternatives?
The dual-beam (D) contacts in TFM-120-01-S-D-A-P-TR provide 2 independent contact points per pin, so a signal path remains intact even if one beam experiences a slight misalignment or contamination. This redundancy reduces contact resistance variation across all 20 positions and is critical in medical imaging, avionics sensor buses, and 5G RF front-ends where signal dropouts at 3.3 V or 5 V logic levels cannot be tolerated.
For a 20-pin sensor interface, how does 0.050" pitch on TFM-120-01-S-D-A-P-TR compare to 0.100" pitch alternatives in PCB area?
A 20-position single-row connector at 0.050" (1.27 mm) pitch spans approximately 24.4 mm in body length, while an equivalent 20-position connector at 0.100" (2.54 mm) pitch would span roughly 48.3 mm. TFM-120-01-S-D-A-P-TR thus saves approximately 24 mm of PCB board space along the connector axis, enabling more compact sensor board designs without reducing the number of signal lines.
Does TFM-120-01-S-D-A-P-TR's anti-vibration feature affect its suitability for automotive or transportation system PCBs?
The anti-vibration (-A) suffix on TFM-120-01-S-D-A-P-TR indicates added mechanical retention features that resist connector disengagement under vibration profiles per IEC 60068-2-6, making it suitable for automotive telematics modules, railway control boards, and drone flight controllers subjected to continuous vibration in the 10 Hz to 500 Hz range. This feature complements the dual-beam contacts to maintain reliable 20-pin signal connections even in high-shock environments.
