Frequently Asked Questions
How does the right-angle orientation of the TSM-125-03-SS-DH-A-K-TR affect PCB layout compared to a vertical strip?
The right-angle (A) configuration routes the 50 mating pins parallel to the PCB surface, allowing the connector to exit from the board edge on a 0.100" (2.54 mm) pitch. This reduces vertical clearance requirements inside enclosures and enables front-panel cable or daughtercard access without increasing board-to-board stack height.
What does the key-lock feature on the TSM-125-03-SS-DH-A-K-TR prevent during field maintenance?
The K (key-lock) option adds a polarization key to the 50-pin housing that physically blocks incorrect connector insertion. This prevents pin-1 reversal and mis-mating on the 0.100" pitch interface, protecting signal integrity and avoiding damage to connected circuits during equipment maintenance or connector swap-out in the field.
Can the TSM-125-03-SS-DH-A-K-TR be used in applications requiring operation from -40°C to +85°C?
Yes, SAMTEC TSM-series connectors are designed for industrial temperature ranges. The TSM-125-03-SS-DH-A-K-TR's housing and contact materials support reliable operation from -55°C to +125°C, comfortably covering the -40°C to +85°C range required by most industrial control and automation standards.
How does the tape-and-reel format of the TSM-125-03-SS-DH-A-K-TR support lean production line management?
Tape-and-reel (TR) packaging provides the TSM-125-03-SS-DH-A-K-TR in industry-standard carrier tape, allowing direct loading onto SMT pick-and-place machines without manual singulation. At production volumes above 500 boards per run, this reduces placement cycle time and minimizes connector handling errors across all 50 positions per device.
