What are the key features of TFC-133-02-LM-D-A?
- 66-position dual-row LM (low-profile mating) configuration at 0.050" (1.27 mm) pitch minimizes vertical stack height in constrained assemblies
- Tiger Eye contact geometry delivers dual-beam wiping action, maintaining contact resistance below 20 mΩ over extended mating cycles
- Cost-effective terminal strip reduces per-circuit connector spend, ideal for high-volume industrial and embedded designs
What is TFC-133-02-LM-D-A used for?
The TFC-133-02-LM-D-A targets low-profile board-to-board signal routing in compact embedded systems, handheld instrumentation, and miniaturized industrial control modules where vertical height is strictly limited. Its LM low-profile mating at 1.27 mm pitch allows 66 circuits to be connected within an assembly height of a few millimeters, supporting slim form-factor product designs. The Tiger Eye contact reliability makes it a dependable choice for instrumentation and data-logger applications operating across wide temperature ranges.

Frequently Asked Questions
What does the LM suffix indicate about the mating height of the TFC-133-02-LM-D-A compared to a standard TFC variant?
The LM suffix designates a low-profile mating stack height for the TFC-133-02-LM-D-A. Compared to standard TFC variants that may mate at full pin-field height, the LM variant reduces the mated assembly height to just a few millimeters, enabling use in slim enclosures and tight PCB stackups. This makes the 66-position 1.27 mm pitch connector suitable for applications where vertical clearance is under 10 mm and a full-height terminal strip would not physically fit.
For a handheld industrial data-logger with 66 signal channels, why would an engineer select the TFC-133-02-LM-D-A over a higher-pitch option?
A handheld data-logger demands both high channel density and a thin PCB stack, and the TFC-133-02-LM-D-A satisfies both constraints. Its 1.27 mm pitch packs all 66 circuits into a connector body under 55 mm long, roughly half the length of an equivalent 2.54 mm pitch strip. The low-profile mating height keeps the two mated boards within a few millimeters of separation, and the Tiger Eye contacts perform reliably from -55°C to +125°C — covering the full outdoor operating range of portable industrial instruments.
How does the cost-effective terminal strip design of the TFC-133-02-LM-D-A affect procurement decisions for a 10,000-unit production run?
For a 10,000-unit production run, the cost-effective terminal strip construction of the TFC-133-02-LM-D-A delivers a meaningfully lower price per circuit compared to premium board-to-board connectors with identical 1.27 mm pitch and 66-position count. SAMTEC's TFC series is designed to reduce BOM cost without downgrading contact reliability, so production teams benefit from Tiger Eye contact performance — rated for over 200 mating cycles and contact resistance under 20 mΩ — at a price point closer to commodity headers.
