Frequently Asked Questions
How many signal positions does the TST-110-05-H-D provide, and what cable assembly type does it mate with?
The TST-110-05-H-D provides 20 positions in a dual-row layout at 0.100 inch (2.54 mm) pitch. It mates with standard 20-conductor IDC ribbon cable assemblies using 0.100 inch dual-row IDC plugs, available in 28 AWG or 26 AWG flat ribbon cable. This compatibility with widely stocked cable assemblies makes the 20-position TST-110-05-H-D easy to integrate into both production wiring and prototype builds for microcontroller I/O boards and industrial sensor modules.
In a microcontroller development board design, what advantage does the shrouded housing of the TST-110-05-H-D offer over an unshrouded 20-pin header?
The shrouded housing on the TST-110-05-H-D physically prevents a 20-conductor ribbon cable from being inserted in reverse orientation, protecting the microcontroller and connected peripherals from reversed power and signal connections. On unshrouded 20-pin headers, a reversed cable insertion at voltages as low as 3.3 V or 5 V could permanently damage GPIO pins or external ICs, making the shrouded version the safer choice for educational boards, field instruments, and any design where non-expert users may handle cable connections.
For a high-vibration industrial automation panel, does the through-hole design of TST-110-05-H-D outperform surface-mount alternatives?
Yes, the through-hole design of the TST-110-05-H-D creates solder joints that anchor 20 pins through the PCB substrate, providing significantly higher mechanical retention than surface-mount pads. In high-vibration industrial automation panels subject to accelerations of 5 g or more from nearby motors and actuators, through-hole solder joints resist fatigue cracking that can affect surface-mount joints, maintaining stable contact resistance below 20 mΩ per pin throughout the product service life.
