What are the key features of TSM-114-04-F-DH-P-TR?
- 28-position dual-row configuration at 0.100-inch (2.54 mm) pitch for versatile mixed-signal and power board connections
- Friction-lock (F) housing prevents accidental disconnection under vibration in industrial and automotive environments
- Polarized dual-header (DH) shroud ensures correct mating orientation and prevents reverse insertion errors
- Tape-and-reel (TR) packaging enabling automated high-volume SMT pick-and-place assembly at 3 A per pin
What is TSM-114-04-F-DH-P-TR used for?
The TSM-114-04-F-DH-P-TR is ideal for industrial control systems, robotics, and embedded computing boards requiring secure 28-position dual-row connections where accidental disconnection or misorientation must be prevented. The friction-lock and polarized housing combination is particularly valuable in field-serviced equipment such as PLC expansion modules and motor controller interface boards where technicians connect and disconnect cable harnesses repeatedly. Its surface-mount termination at 2.54 mm pitch and tape-and-reel packaging support efficient automated assembly in medium-to-high volume PCB manufacturing runs.

Frequently Asked Questions
How does the friction-lock (F) feature of the TSM-114-04-F-DH-P-TR protect connections in vibrating industrial equipment?
The friction-lock housing requires a deliberate extraction force of several Newtons to disengage the mated connector pair, preventing the 28-position assembly from backing out under vibration frequencies common in motor drives and conveyor systems operating at 50 Hz to 200 Hz. This is a critical advantage over standard unshrouded headers where vibration can cause intermittent contact resistance increases and signal dropouts.
What does the polarized dual-header (DH) designation mean for technicians installing cable harnesses on the TSM-114-04-F-DH-P-TR?
The DH (dual-header) shroud includes a polarization key that physically prevents the mating connector from being inserted in the wrong orientation. For the 28-position assembly, this eliminates a common wiring error that could apply reversed voltages (for example 5 V on a ground pin) or swap differential signal pairs, protecting sensitive downstream circuits from damage during field service or initial board bring-up.
What current per pin does the TSM-114-04-F-DH-P-TR handle, and for which voltage rails is it commonly used?
Each of the 28 pins supports 3 A of continuous current, giving a total capacity of 84 A across all positions. In typical embedded and industrial designs, the connector carries a mix of 3.3 V and 5 V digital signal lines alongside 12 V or 24 V auxiliary power pins, leveraging the full 3 A rating on power positions while signal pins draw under 0.5 A.
Is the TSM-114-04-F-DH-P-TR well-suited for reflow SMT assembly in high-volume production?
Yes, the -TR suffix confirms tape-and-reel packaging for automated pick-and-place SMT equipment, and the 0.100-inch (2.54 mm) pitch surface-mount pads conform to IPC-7351 land pattern standards. The connector is rated to withstand lead-free reflow profiles peaking at 260°C, ensuring reliable solder joint formation across all 28 positions in high-volume production runs.
