Key Features
- 1.27 mm (0.050") pitch dual-row terminal strip with 84 positions supporting high-density signal interconnects in space-constrained PCB designs
- Tiger Eye contact technology delivering high normal force and reliable low-resistance mating across thousands of insertion cycles
- Low-profile SMT construction with dual-row layout enabling dense board-to-board or board-to-cable connections in compact electronic assemblies
Applications
The TFM-142-23-LM-D is suited for high-density board-to-board interconnects in aerospace, defense, and high-reliability industrial electronics where connector failure is not acceptable. Its 1.27 mm pitch and 84-position dual-row layout efficiently routes large signal buses in rack-mount equipment, FPGA development boards, and test instrumentation. The Tiger Eye contact design withstands repeated mating cycles common in field-serviceable modules.

Frequently Asked Questions
How many positions and what pitch does the TFM-142-23-LM-D provide?
The TFM-142-23-LM-D is a dual-row terminal strip with 84 total positions (42 per row) arranged on a 1.27 mm (0.050") pitch. This tight pitch supports high signal density while keeping the connector footprint compact, making it ideal for space-constrained PCBs in industrial or defense applications.
What makes the Tiger Eye contact technology in TFM-142-23-LM-D suitable for high-reliability designs?
Tiger Eye contacts provide an elevated normal force at the contact interface, ensuring stable electrical connection with contact resistance below 20 mΩ even after repeated mating cycles. This design is particularly valuable in applications experiencing vibration or thermal cycling between -55°C and +125°C where intermittent contact is unacceptable.
In which board-to-board spacing scenarios is the TFM-142-23-LM-D a good choice over wider-pitch alternatives?
The 1.27 mm (0.050") pitch of the TFM-142-23-LM-D is preferred when routing 84 signals would require excessive board area using 2.54 mm pitch connectors. Applications such as FPGA mezzanine cards, where 84 I/O lines must pass between stacked boards separated by 8 mm to 20 mm, benefit from this compact footprint and robust Tiger Eye retention.
