Key Features
- 82-position dual-row right-angle female socket (LM) at 0.050 inch (1.27 mm) pitch for right-angle board-to-board or card-edge interconnection
- Tape-and-reel (TR) packaging enabling automated pick-and-place assembly for high-volume production with consistent placement accuracy
- Keyed (K) connector design providing polarized mating to prevent incorrect insertion across all 82 positions in the dual-row layout
- Cost-effective Tiger Eye construction delivering reliable 82-channel interconnection at a competitive price point for volume PCB production
Applications
The TFC-141-02-LM-D-K-TR is designed for right-angle board-to-board or board-to-backplane connections in embedded computing systems, industrial automation controllers, and telecommunications equipment where 82-position dual-row keyed connectivity is needed. The tape-and-reel packaging optimizes its use in automated SMT manufacturing lines for mid-to-high volume production of server line cards, industrial I/O modules, and FPGA expansion boards. Its keying feature ensures correct board orientation during daughtercard insertion, preventing assembly errors in field-replaceable module architectures.

Frequently Asked Questions
What does the LM suffix on TFC-141-02-LM-D-K-TR indicate about connector orientation?
The LM suffix on TFC-141-02-LM-D-K-TR designates a right-angle female socket interface, meaning the 82-position dual-row connector body sits parallel to the PCB surface with contacts exiting at a 90-degree angle. This right-angle orientation is used for card-edge or board-to-backplane connections where the mating direction is parallel to the PCB plane, common in server line cards, industrial modular systems, and FPGA development boards at 0.050 inch pitch.
How does the K keying option on TFC-141-02-LM-D-K-TR prevent connector mismating?
The K keying option on TFC-141-02-LM-D-K-TR adds a physical polarization feature to the 82-position dual-row connector body that matches only with correspondingly keyed male headers, preventing incorrect 180-degree insertion or mismating with similar but non-keyed connectors. This is critical in field-replaceable module systems, server blades, and industrial daughterboards where incorrect insertion of an 82-pin connector could cause signal shorts or permanent damage to the PCB and components.
Why is the TR tape-and-reel packaging important for TFC-141-02-LM-D-K-TR in production environments?
The TR (tape-and-reel) packaging of TFC-141-02-LM-D-K-TR is essential for high-volume automated SMT production lines where pick-and-place machines must handle thousands of connectors per shift. Reel packaging ensures consistent connector orientation and spacing for reliable robotic pick-up at the 82-position dual-row 0.050 inch pitch size, reducing placement errors, minimizing manual handling, and lowering total assembly cost per board compared to tube or tray packaging for large production runs.
For which industrial or embedded computing applications is TFC-141-02-LM-D-K-TR a strong fit over a vertical connector alternative?
TFC-141-02-LM-D-K-TR is a strong fit for applications where board height constraints require a low-profile right-angle connector, such as chassis-mounted industrial controllers, rack-mounted server blades, and embedded computing modules that slide into card guides with limited vertical clearance. The right-angle 82-position dual-row design at 0.050 inch pitch reduces board height above the PCB while maintaining 82-channel signal and power routing capability, offering a space-efficient alternative to vertical connectors in height-constrained enclosures.
