Key Features
- High-reliability Tiger Eye dual-row terminal strip on 0.050" (1.27 mm) pitch with 58 total positions
- Latching contact system (LC) provides positive retention to prevent accidental disconnection under vibration or shock
- Low-profile mounting (LM) minimizes vertical stack height in tight board-to-board assemblies
- Designed for demanding mil/aero and industrial applications requiring reliable signal integrity over extended service life
Applications
The TFM-129-01-LM-D-LC serves high-reliability board-to-board interconnect needs in military, aerospace, and rugged industrial systems where 0.050" pitch, 58-position dual-row connections must remain secure under mechanical shock and vibration. The latching contact system ensures positive retention in avionics modules, defense electronics, and field-replaceable units subject to environmental stress. Its low-profile mounting variant suits tightly stacked PCB assemblies in rack-mount and portable equipment enclosures.

Frequently Asked Questions
What does the LC (latching contact) suffix mean for the TFM-129-01-LM-D-LC in vibration-prone environments?
The LC suffix indicates a latching contact system that mechanically locks the mating connectors together once engaged, preventing accidental disconnection under vibration or mechanical shock. This is critical in avionics, military ground vehicles, and industrial machinery where a 58-position, 0.050" pitch board-to-board connection must remain reliable across thousands of operating hours in environments with significant vibration or shock loads.
How does the low-profile mounting (LM) option of the TFM-129-01-LM-D-LC benefit PCB stack height in compact designs?
The low-profile mounting (LM) designation means the connector's mated stack height is minimized, typically reducing board-to-board spacing to just a few millimeters compared to standard-height Tiger Eye connectors. This is essential in portable electronics, rack-mount equipment, and avionics boxes where every millimeter of PCB stack height affects enclosure size and thermal management for the 58-position dual-row interconnect.
For which high-reliability application sectors is the TFM-129-01-LM-D-LC typically specified instead of commercial-grade 0.050" connectors?
The TFM-129-01-LM-D-LC is specified in military, aerospace, and harsh industrial sectors where commercial-grade 0.050" (1.27 mm) pitch connectors lack adequate vibration resistance or cycle-life ratings. The Tiger Eye high-reliability contact system combined with the latching mechanism makes it suitable for defense electronics, avionics LRUs, downhole instrumentation, and any application demanding high pin density at 58 positions with guaranteed retention over 200 or more mating cycles.
